(Preview) A Call to Action for TSMC’s AI Customers, Wall Street’s Netflix Anxiety, Q&A on Tech’s Cignetti, OpenAI, Starbucks

Andrew SharpBen Thompson

Podcast
TL;DR
  • TSMC’s pricing restraint is less a mystery of bargaining power than a legacy of the customer-first model that built its dominant position. It won trust by guaranteeing capacity, not competing with clients or taking their IP, and running paid-off fabs for decades; Thompson thinks that habit left 5 nm and 3 nm underpriced just as leading-edge fabs became shorter-lived and cost “well into the 30 billions.”
  • The bigger investor issue is capacity: TSMC plans $52–56 billion of capex this year versus $41 billion in 2025 and roughly $30 billion in preceding years, yet cost inflation means supply will grow less than the headline increase. Today’s investment decisions shape 2028–29 output; TSMC rationally fears a 2028 AI-bubble break leaving idle fabs, but its restraint may leave customers undersupplied.
  • TSMC is not eliminating risk; it is transferring it downstream as permanently foregone revenue for NVIDIA, Microsoft, Google and other AI buyers. Thompson’s “TSMC brake” is the supply ceiling behind CEOs saying they could sell more with more capacity: choosing the safest foundry may actually load greater fab risk onto customers.
  • The call to action is for hyperscalers and model labs to make Intel and Samsung credible second sources now, despite three-to-four-year porting cycles and near-term execution risk. Competition would make TSMC fear losing sticky, multi-year customers more than distant overcapacity; simply flying to Taiwan to ask it to “please invest more” enables the brake.
  • For AI buyers, the desirable end state is deliberate foundry overbuilding, because the downside is excess capacity and “super cheap chips” while the upside is enough supply to monetize demand. Thompson calls current buyers “chickens” for avoiding Intel and Samsung; if they wait, too little capacity could itself help burst the AI bubble in 2028–29.
  • The supply-chain concentration is geopolitical as well as financial: Sharp objects that Dario Amodei likened China-bound AI chips to nuclear weapons to the absence of any mention of Taiwan. If the “nuclear weapons plant” sits roughly 80 miles off China’s coast, alternative foundries hedge both undersupply and the war scenario Sharp raises.
Digest · the substance, structured for research

1. TSMC’s neutral-foundry promise became a geopolitical choke point

  • Sharp’s opening rant targets an omission: whenever Dario Amodei compares supplying China with giving nuclear weapons to North Korea, Sharp searches for “Taiwan” and finds nothing. If AI chips are that strategic, he asks, what does it mean that their essential “nuclear weapons plant” is roughly 80 miles from China?

  • TSMC began about 40 years ago with process technology from Philips and little else. It trailed the leading edge by perhaps five generations, so its proposition was reliability: customers received guaranteed capacity rather than being displaced whenever an integrated producer such as Intel or Texas Instruments needed its own factories.

  • Neutrality supplied the second moat. Because TSMC made no competing chips, it could promise, “We’re not going to crowd you out,” and would not appropriate customer IP; Sharp notes that Samsung could separate foundry and product operations, but Apple would still face a fundamental conflict when manufacturing through a smartphone rival.

  • Sharp wonders whether a Taiwan disruption would merely leave consumers using iPhone 13-level chips. Thompson reverses the premise: attention fixates on leading-edge processors, but the harder replacement problem is the multitude of legacy chips for which the US has little capacity beyond whatever GlobalFoundries might supply.

2. Leading-edge economics broke the run-it-forever pricing model

  • TSMC historically depreciated a fab over perhaps five years but operated it far longer; some late-1990s facilities still produce ancient, standardized parts for pennies after their capital costs have been recovered. That longevity joined a “customer-centric, customer-first mindset” to an ingrained low-cost culture.

  • The model weakened at a turning point around 2014 or 2015, when chips became more expensive. Some buyers stopped at 28 nm—where Thompson says China invested heavily—because performance gains no longer justified the premium; 7 nm, described in the discussion as the first EUV node, became somewhat stranded as leading-edge customers moved onward.

  • TSMC’s decision to rework some 5 nm capacity for 3 nm signaled that advanced fabs were not merely costlier but shorter-lived. The company had to become “like Intel” in a positive sense: capture value upfront rather than rely on decades of trailing revenue. Thompson thinks 5 nm and 3 nm were underpriced precisely when there was “no alternative.”

  • Thompson’s “Ben conjecture,” explicitly “not reporting,” is that insufficient pricing might help explain former CEO and chairman Mark Liu’s abrupt retirement, perhaps with Morris Chang’s fingerprints involved. The contrast is Chang’s 2008 return: amid recession and retrenchment, he called the downturn TSMC’s biggest opportunity and invested into the smartphone era.

3. Today’s capex sets a hard ceiling on 2028–29 AI supply

  • After ChatGPT happened, around 2022, TSMC had to estimate demand for 2025 and 2026. Thompson argues that its conservative 2022–24 spending decisions now explain why capacity falls far short of AI demand: semiconductor commitments take years to become working supply.

  • Planned capex rises to $52–56 billion this year from $41 billion in 2025 and roughly $30 billion in earlier years. Sharp initially reads that as nearly a doubling; Thompson corrects him to roughly 25% year over year, while stressing that pricier equipment makes the relationship between dollars and added capacity worse than linear.

  • That spending is principally a decision about 2028 and 2029, not 2026. TSMC’s fear is reasonable: if the AI bubble breaks in 2028, several years of investment could leave expensive equipment without customers. Because the business is so capital-intensive, Thompson says the outcomes can run from extraordinary profitability to, at the extreme, “you’re going bankrupt.”

4. TSMC’s caution converts foundry risk into customer revenue loss

  • Thompson’s central mechanism is that “risk doesn’t disappear from the system.” By limiting overbuild risk on its own balance sheet, TSMC creates foregone revenue for NVIDIA, Microsoft, Google and others; when CEOs say, “If we had more capacity, we would’ve sold more,” those permanently lost sales are downstream of insufficient foundry capacity.

  • This is the “TSMC brake”: one supplier gates the AI infrastructure build-out and moderates potential bubble conditions. Customers believe they are de-risking by choosing the best process and most dependable service, but constrained output means they are “loading on fab risk to themselves.”

  • Sharp’s formulation, which Thompson accepts, is that TSMC would rather choose something like a 67% increase over earlier spending than a 167% increase, sacrificing possible profit to limit tremendous downside risk. Thompson’s qualification is decisive: “TSMC is doing what is right for TSMC,” and can do so because it lacks competition.

  • Asked whether dependence on NVIDIA, Apple and AMD creates customer-concentration risk, Thompson says the immediate problem is the opposite: TSMC has too many customers and insufficient capacity. It must avoid prices high enough to prompt departures while supplying enough leading-edge chips that customers do not leave involuntarily.

5. AI buyers must manufacture the competition TSMC lacks

  • NVIDIA previously maintained leverage by splitting Ampere-generation production—gaming chips at Samsung and server chips at TSMC. Today, TSMC remains best; Intel 14A “maybe” looks promising, but committing now may not produce chips for three or four years, and mapping a design to another process is never trivial.

  • A credible Intel or Samsung would change TSMC’s governing fear from unused capacity five years out to losing customers today. Foundry switches are multi-year commitments and difficult to reverse, so prospective customer defections would pressure TSMC to invest more while the new suppliers also added capacity.

  • Thompson calls the approach of flying to Taiwan and begging TSMC to invest more “totally wrong”; he says Sam Altman should explore Intel instead. Limited supply lets TSMC choose winners, leaving customers afraid to antagonize it, but begging merely enables the brake. That is also his response to OpenAI’s repeated “we don’t have enough compute” complaint: help create the missing alternative.

  • Buyers should want every foundry overbuilding: the downside is “super cheap chips,” lower capital costs and ample volume. Thompson says self-described capitalists must “sack up”; otherwise the 2028–29 opportunity might be killed by capacity itself. Sharp adds war as another diversification case, while Thompson calls long-horizon hardware planning “a new muscle for Silicon Valley.”

Andrew Sharp

Hello, and welcome to a free preview of Sharp Tech. Hello, and welcome back to another episode of Sharp Tech. I'm Andrew Sharp. Joining me in the same room today is Ben Thompson. Ben, how are you doing?

Ben Thompson

Pretty flustered. Apparently, I’d forgotten—I don’t know that I ever knew—that your podcast voice is a good 15 decibels louder than your regular voice.

Andrew Sharp

A little bit. I was just lectured as I did my hello. I’m trying to speak in hushed tones here as we record in person because I was allegedly too loud. I listened back; it sounded normal, but here we are, sharing your basement together.

Ben Thompson

Yeah, I don’t know what to say. It’s not quieter at all.

Andrew Sharp

He really is flustered here.

Ben Thompson

I know. It’s been a day of fluster, to be totally honest. Hilariously, we planned for you and some other folks in the Stratechery universe to come visit this weekend, which is going to be the coldest weekend in literally 45 years or something like that.

Andrew Sharp

Yeah.

Ben Thompson

I’m trying to talk loud on the podcast today because this is actually going to be the last podcast that I’m ever able to record. Twenty below is the low tomorrow in Madison. I’m glad that I’m actually experiencing real Wisconsin winter, though, with my first trip.

Andrew Sharp

I don’t think you’re glad, because you showed up in loafers and no socks.

Ben Thompson

Hey.

Andrew Sharp

It was one of the most unbelievable sights I’ve ever seen in my life: Andrew Sharp coming down the airport stairs utterly unprepared for what he was about to encounter.

Ben Thompson

And immediately being roasted by Ben for about 10 minutes straight for the loafers. But look, one of my rules for adulthood is you have to dress well when you’re traveling, so I had a nice pair of loafers, nice pair of slacks, a nice little Henley here. Casual. Don’t do too much when you’re flying. But I felt good. Look good, feel good, feel good, play good.

Andrew Sharp

You say that now.

Ben Thompson

Or podcast good.

Andrew Sharp

Yeah, I asked to hold your hand walking to the car to make sure you didn’t slip. But—

Ben Thompson

Yeah, loafers with no socks. I’m going to have frostbitten ankles. That’s my best-case scenario for tomorrow’s weather.

In any event, here we are. We have a lot to get through today, and we’re going to begin with one of the most important tech companies of the century, and a company that we actually don’t talk about very much on the podcast. So I’m going to read a note from Sam.

Andrew Sharp

That’s a you problem, not a me problem.

Ben Thompson

I was thinking about it. I was like, it’s probably my fault that we never discuss TSMC. You certainly write about TSMC plenty, but—

Andrew Sharp

Well, before it was cool, for the record.

Ben Thompson

That’s true. You were early. Early on everything. That’s why people subscribe to Stratechery.

Sam says, “Ben and Andrew, what is stopping TSMC from charging more insane margins? They have clearly increased their margins after the AI boom, but they’re the only option in town, and especially during the duration of this bubble, nobody can go anywhere else. Don’t they have such insane leverage in the current moment that Apple and Nvidia would pay basically whatever they charge? Why have their margins not increased more?”

So, Ben, we get this question every couple of months. We actually answered it about two and a half years ago, but the same question came to mind for me. I was reading about the H200s and Nvidia having to go to TSMC and negotiate for more capacity in order to serve the H200 orders, and it was just a reminder that basically anyone who’s doing anything in AI is ultimately going through TSMC. You wrote about them earlier this week. Do you have an answer for Sam? Why aren’t they able to just extract crazier and crazier margins from everybody?

Andrew Sharp

Well, before we get to that, I do want to compliment you, especially since I revealed your sartorial choices to the world and how inappropriate they were. At least you think about TSMC and the fact that all the AI chips come from there. That is a big improvement over everyone.

Ben Thompson

Everyone.

Andrew Sharp

Well, you had Dario Amadei at Davos this week talking about how giving chips to China is like giving nuclear weapons to North Korea.

Ben Thompson

Mm-hmm.

Andrew Sharp

And what did I do? As I do with every article or every comment from him about this issue, I do a Control-F. I search the document that I’m reading. I type in “Taiwan,” and there are no results.

Ben Thompson

No mention.

Andrew Sharp

Can we actually—

Ben Thompson

Mm-hmm.

Andrew Sharp

If these are the same as giving nuclear weapons to North Korea, what does it mean if the nuclear weapons plant is 80 miles—

Ben Thompson

A stone’s throw.

Andrew Sharp

—off the coast of China?

Ben Thompson

Yeah.

Andrew Sharp

Can we think through the totality of this issue?

Ben Thompson

Mm-hmm.

Andrew Sharp

Anyhow, that rant aside: TSMC margins. This is actually an interesting time to revisit this question. In broad strokes, TSMC—I don’t know, how long do you want me to go on this? There really is a cultural aspect to this. You have to remember TSMC starts 40-some years ago.

Ben Thompson

Mm-hmm.

Andrew Sharp

And they have nothing. They get some process technology from Philips. There’s actually an interesting universe of Philips spinoffs. ASML is also a Philips spinoff. TSMC is one. There are several other ones in this ecosystem.

But what they can offer is the fact that they have nothing to offer. And what I mean is, if you’re someone who has an idea to make a chip, you can go to them. Number 1, you can get guaranteed capacity—you’re not going to get crowded out. Because at that point, the alternative is you go to Texas Instruments, you go to Intel—maybe Intel—you beg for extra capacity, which, by the way, if they suddenly have more sales than they need, you get booted out.

Ben Thompson

Right.

Andrew Sharp

And by the way—

Ben Thompson

So when you say what they can offer, you’re referring to TSMC back when they were trying to take market share in the beginning, right?

Andrew Sharp

This is literally all they had: Number 1, we can guarantee you capacity; we’re not going to crowd out your order. And number 2, because we’re not making our own chips like Texas Instruments—

Ben Thompson

We’ll work with you—

Andrew Sharp

—or Intel—

Ben Thompson

—to make whatever you want to make.

Andrew Sharp

No, we won’t take your IP.

Ben Thompson

Oh, yeah.

Andrew Sharp

That’s right.

Ben Thompson

Which is a very real and legitimate concern. There are aspects of Intel that are still not trusted in that regard.

Andrew Sharp

Samsung ran into that issue as well, right?

Ben Thompson

It’s a little more complicated because, obviously, Apple used to be on Samsung. I think Samsung’s done pretty well in terms of having a wall between their foundry business and the rest of their business, but there is a fundamental conflict of interest. If you’re Apple making your chips at Samsung and Samsung is competing with you, that—

Andrew Sharp

Right. I recall reading something about that tension in the Apple in China book, but I don’t know exactly what the circumstances were. But either way, in broad strokes, the conflict of interest just does not exist at TSMC, which makes it easier for everybody.

Ben Thompson

And that was literally their selling point.

Andrew Sharp

Yeah.

Ben Thompson

It’s like, “We’re not going to crowd you out because, by the way, our process is like 5 processes behind the leading edge.”

Andrew Sharp

Mm-hmm.

Ben Thompson

So you start out and you’re making your basic chips, right? The things that we don’t even think about—we didn’t think about until COVID, when we suddenly ran out of these super-basic chips and nothing could be made.

So they come, and then the other thing is, it’s going to be super cheap, as cheap as we can offer it. What we’re going to do is build these fabs, and they will depreciate over 5 years or whatever the number is.

Andrew Sharp

Yeah.

Ben Thompson

But we’re going to run those fabs forever. Now, their earliest fabs have long since been closed down, but they still have fabs from the late 1990s. 1998 or 1999, I think, is maybe the oldest fab that they still have in operation, which is making these ancient chips that are fine for what they are. And there are certain products, long-lived products, that have just been standardized on this chip for ages and ages.

Andrew Sharp

Sure.

Ben Thompson

And they sell these chips for pennies.

Andrew Sharp

Money on top, though, I mean—

Ben Thompson

Right. But it’s—

Andrew Sharp

They’ve already invested in the fab.

Ben Thompson

It’s already paid for.

Andrew Sharp

Yeah.

Ben Thompson

Yep, exactly. And so you have, in general, this very customer-centric, customer-first mindset because that was literally the only thing they could sell, combined with this low-cost mentality—that’s what we have to offer.

We don’t have the fastest chips. We don’t have the leading-edge processes, but we’re a reliable partner for you.

Andrew Sharp

So culturally, is it a struggle, then, to be extracting crazy margins because of the way they began?

Ben Thompson

Yes.

Andrew Sharp

Okay.

Ben Thompson

That's basically it. So it's been a really difficult transition from that to being the leading edge.

Andrew Sharp

The premium provider.

Ben Thompson

And this is one of the things that I've written about a fair bit. I think it would have made a lot of great podcast material, but unfortunately you didn't care.

One thing that was really interesting a few years ago was that they have this model: You build a fab once, and you run it forever.

They incurred extra costs, I think this was 2 or 3 years ago, because they said, “We're going to basically rework some of our 5-nanometer fabs to be 3-nanometer.”

What's interesting about that is that one of the challenges they have is these 7-nanometer fabs that are still included in their advanced-fab numbers. But they're a little bit stranded because there was a turning point somewhere around 2014 or 2015 when chips just definitely got more expensive. If you didn't need the speed or the efficiency, you could just stop.

Mm-hmm.

Ben Thompson

Actually, the biggest stopping point was probably 28 nanometers. There's just a lot of demand there, and that's where China has really invested a ton. The chips are good enough, and it's not worth the price premium to go to the next step down.

Ben Thompson

I wonder about that on a more general basis when people talk about Taiwan invasion scenarios. If everybody had to run on iPhone 13-level chips, how many people would actually notice the difference between what we have now and what we had then?

Ben Thompson

Well, no, the problem is actually the opposite. I wrote about this a few years ago, when I think the chip ban went down. My point there was that people are thinking too much about the leading edge.

Ben Thompson

Right.

Dylan Patel

The real issue is—

Ben Thompson

The legacy chips.

Ben Thompson

There are all these legacy chips that the U.S. has no capacity for. I mean, GlobalFoundries might have something or other. But the reason they don't have it—and why Intel doesn't have it—goes back to the 5-nanometer or 7-nanometer story. Intel was always on the cutting edge.

Ben Thompson

Mm-hmm.

Ben Thompson

That was their differentiation. They internalized all the gains from that by thinking, “We could sell the fastest chips because we have the best manufacturing.” But when they went to the next generation, they would dismantle the old generation, or they would try to reuse as much stuff as they could going forward. They didn't keep fabs going on forever.

Ben Thompson

Mm.

Ben Thompson

What that meant was that, if you had this 5-year depreciation, you needed to pay for the fab in those 5 years.

Ben Thompson

Yeah.

Dylan Patel

But they could do that because they could charge very high margins.

Ben Thompson

So they're taking margin, no question.

Ben Thompson

Yes, they would charge very high prices and pay for it. What happened to TSMC is that you had this overall market issue where the 28-nanometer fab you built back in the day was the fastest of its time, but then it just became a great line that you could run for 40 years.

Ben Thompson

Mm-hmm.

Ben Thompson

That old model sort of worked. When you got down to this point, you really saw it happen with 7 nanometers. It was expensive because that was the first one using EUV, and it just wasn't worth it for—

Ben Thompson

For most customers.

Dylan Patel

For most customers.

Ben Thompson

Yeah.

Ben Thompson

So it became a little bit of a stranded node, to an extent. It's still used, but—

Ben Thompson

That makes sense because all the people who would pay to be on 7 nanometers would then pay to be on—

Dylan Patel

They moved on.

Ben Thompson

—5 nanometers.

Dylan Patel

They'd already moved on.

Ben Thompson

Or 3 nanometers.

Dylan Patel

Right.

Ben Thompson

Yeah.

Ben Thompson

What was so interesting about this announcement—“Oh, we're going to incur more costs to transition”—was that they had to become like Intel.

Ben Thompson

Mm-hmm.

Ben Thompson

They had to start thinking that these incredibly expensive fabs don't just cost way more; they're also shorter-lived.

Ben Thompson

Yeah.

Ben Thompson

We're not necessarily going to be able to run them forever and get the money back, which means we have to raise prices. It was almost more of a bottom-up realization that they needed to raise prices and make more margin.

Ben Thompson

Otherwise, we're going to be underwater on this 7-nanometer investment, or 5-nanometer investment.

Ben Thompson

Right. They're not underwater, to be clear.

Ben Thompson

Right.

Ben Thompson

But the problem is that money you don't make, you don't get back. You don't get to go back to Apple and say, “3 years ago, we probably should have charged you more.”

Ben Thompson

Well, these are just tremendously expensive investments.

Ben Thompson

Oh, yeah. The latest ones are well into the $30 billions. Those 7-nanometer ones were probably $15 billion or $20 billion or something like that. I'm just pulling that out of thin air. I'm not—

Ben Thompson

So if you're putting $30 million, or $30 billion, down—

Ben Thompson

Yeah, was I saying millions? Yeah.

Ben Thompson

A million would be great.

Ben Thompson

Big difference between millions and billions. What's interesting about this is that this is also combined with the overall situation. A huge strength of TSMC is that it's very customer-centric.

Ben Thompson

Mm-hmm.

Ben Thompson

They are a customer-service organization. This is by far the hardest thing for Intel, and it will continue to be the hardest thing for them to figure out: being customer-first. But as part of that, TSMC has had a natural disinclination to jack up prices.

Ben Thompson

Mm-hmm.

Ben Thompson

Of course, they would talk about this: “Yes, of course, we need to raise prices, but we also are cognizant of a long-term relationship,” and so on. There's a bit about this where that's actually a good thing because they keep loyal customers. You don't just decide, “I'm going to go with Intel this time.” It's a multiyear commitment even to go to another foundry.

Ben Thompson

Okay.

Ben Thompson

That sort of locks them in even more. But what happened was—and this part is all, just to be clear, what’s the word I'm looking for?

Ben Thompson

Ben theory?

Ben Thompson

Ben theory. Maybe a tiny bit of scuttlebutt infuses this. What happened with this 7-nanometer bit of stranding, and then when 3 nanometers launched, is that you had this period where TSMC was by far in the lead.

Ben Thompson

Mm-hmm.

Ben Thompson

There were no alternatives. Their old model wasn't quite working anymore. They needed to switch to this model, and they did not raise prices nearly enough.

Ben Thompson

Mm.

Ben Thompson

I think that might be what happened to the previous, previous CEO, who became the chairman of the board and then suddenly retired.

Ben Thompson

Who was that?

Dylan Patel

Mark Liu.

Ben Thompson

Okay.

Ben Thompson

Again, this is just my theory. It was a weird transition and a weird thing that happened. What I think happened is that TSMC insufficiently raised prices. It cost them a lot of money that's sort of gone forever, and it came from this inherent customer-centric, conservative, bottom-up mindset. This bottom-up, cost-plus sort of thinking is very endemic to Taiwanese business culture.

Ben Thompson

Yeah.

Ben Thompson

Whereas what TSMC needs to do, to this emailer's point, is become more like Intel.

Ben Thompson

Mm-hmm.

Ben Thompson

They were forced into that in terms of how long they can depreciate their assets and having to learn how to reuse stuff, but that means they need to do it from a pricing perspective, too. People hated Intel not just because it was arrogant, but because Intel knew it was the best—

Ben Thompson

Putting the screws to them.

Dylan Patel

—and absolutely captured its value.

Ben Thompson

Well, I'm glad that we don't have to lay the failure to raise prices at Morris Chang's feet, because I love—I consider the story of him coming out of retirement to lead the smartphone era of TSMC one of my favorite stories. I consider him the Michael Jordan—

Ben Thompson

That is part of the story.

Ben Thompson

—of tech CEOs.

Ben Thompson

I'm glad you brought that up, because what happened there? TSMC was in an increasingly strong position—not fully caught up to Intel, but very caught up to Samsung in terms of making ARM chips and being the third-party foundry. Then the global financial crisis happened. The world went into recession, and you had this conservative instinct to pull back.

Ben Thompson

Right.

Dylan Patel

Morris Chang comes in—

Ben Thompson

That's my guy, Morris.

Dylan Patel

—fires everyone, and says, “This is the biggest opportunity this company has ever seen. We're investing in this.”

Ben Thompson

Wearing number 45.

Dylan Patel

“This is the biggest opportunity this company has ever seen.”

Ben Thompson

Yep.

Dylan Patel

“We're investing in this.” And that's how this whole last 15 years happened.

Ben Thompson

Now, is Morris Chang involved? I feel like if the former CEO, then chairman of the board, unceremoniously retires when I don't think he was ready to retire, that might have Morris Chang's fingerprints on it.

Ben Thompson

May have been a little bit involved. Yes. Again, this is pure conjecture. That's what we're looking for.

Andrew Sharp

Yes. Okay.

Ben Thompson

This is Ben conjecture.

Andrew Sharp

Ben conjecture.

Ben Thompson

A tiny bit of scuttlebutt. There might be something here, but this is not reporting. This is conjecture. Regardless, around this timeframe, I was hammering on this in the Daily Update.

Andrew Sharp

Yeah.

Ben Thompson

I'm like, "TSMC is screwing up its pricing," and it's a problem for all of them. It's not just that, to the emailer's point, they have the opportunity. It's that their fundamental structure of their business is changing. They're becoming like Intel, whether they want to be or not—Intel in a positive sense, where they're on the leading edge.

They have to capture a margin much more upfront. They can't count on this trailing in the back end. They need to capture their value, and they need to capture their value then. The reason why it was so damaging with those 5-nanometer and 3-nanometer nodes—I think those 2 nodes were underpriced—was that at the time there was no alternative.

Andrew Sharp

Right.

Ben Thompson

So, fast-forward to today—

Andrew Sharp

That was going to be my question, because when we had a conversation along these lines 2½ years ago, you talked about NVIDIA wanting to second-source, or at least have another player that they could pit against TSMC.

Ben Thompson

Which they did, which they always did. Their previous generation, or a few generations ago, was the Ampere generation.

Andrew Sharp

Mm-hmm.

Ben Thompson

They did the gaming chips with Samsung, and then the server chips with TSMC.

Andrew Sharp

And that's how NVIDIA was able to keep TSMC from extracting too much margin in the value chain. Is there anybody who can play that role today, or is it basically just TSMC that's able to serve the AI demand right now?

Ben Thompson

Well, this is where it gets really interesting, and this is what I was writing about this week. The issue is TSMC is the best.

Andrew Sharp

Mm-hmm.

Ben Thompson

Still the best, probably will continue to be the best. There's certainly rumblings about Intel, about 14A maybe being good. But even there, if you commit to Intel today, you're not going to have chips coming off the line for 3 or 4 years.

Andrew Sharp

Yeah.

Ben Thompson

It's a maybe. Now, again, people might have already committed. It's not announced, so that could happen sooner. Or the same thing with Samsung. It's not a trivial thing to map a chip onto a new process.

If TSMC is there and willing, and the best, why would you want to go somewhere else?

Andrew Sharp

And take that risk—

Ben Thompson

Take that risk.

Andrew Sharp

—3 or 4 years out.

Ben Thompson

Exactly. The issue, however, is that I think it's fair to say it's clear now—

Andrew Sharp

Mm-hmm.

Ben Thompson

—that the conservatism that Morris Chang fired everyone for in 2008—

Andrew Sharp

Yeah.

Ben Thompson

—and the conservatism that led to them underpricing 4 or 5 years ago—

Andrew Sharp

Yeah.

Ben Thompson

—it has manifested itself in their CapEx.

Andrew Sharp

Okay.

Ben Thompson

What I mean is, after ChatGPT happened, there was a choice to make: How much demand do we think there's going to be in 2025 and 2026? So this was—what? Wait, 2022?

Andrew Sharp

Mm-hmm.

Ben Thompson

TSMC was relatively conservative, and the net result is that, because these decisions are made years ahead of time—this is what's so hard about semiconductors—the issue is that there just isn't nearly enough capacity at TSMC for all the demand.

Andrew Sharp

Mm-hmm.

Ben Thompson

Everyone's stuck, because to go somewhere else is going to take a few years. But at the same time, TSMC isn't there, and the other ones aren't good enough. So you had this whole thing last year of Sam Altman visiting Taiwan, and Jensen's here, and everyone's like… They're basically coming to TSMC saying, "Please invest more."

Andrew Sharp

Mm-hmm.

Ben Thompson

But the tricky thing is, the "invest more" isn't about 2026. The "invest more" is about 2028 and 2029.

Andrew Sharp

Yeah.

Ben Thompson

TSMC comes out—the reason why this is a big deal for earnings is they announced their CapEx plans, and they announced, I think, that they would spend between $52 and $56 billion on CapEx this year. A lot of money.

Andrew Sharp

Mm-hmm.

Ben Thompson

This year, they spent $41 billion. I think last year, they spent $30 billion, which was way too low. The last 3 years were really—or probably the 2022 to 2024 era was—particularly too low.

This raises a really interesting question for all of the TSMC customers: Is $52 to $56 billion, in a context of prices being up in general and all the equipment being more expensive, enough? That's not a linear increase in capacity. The curve bends in the wrong way because just stuff in general is more expensive. Is that enough for—

Andrew Sharp

Is it enough?

Ben Thompson

—the demand in 2028 and 2029?

Andrew Sharp

Even doubling it, is that enough? I mean—

Ben Thompson

Well, but they're not doubling it. It's like a 25% increase from last year.

Andrew Sharp

Okay.

Ben Thompson

So—

Andrew Sharp

I thought it was $30 billion, and now it's $52 billion.

Ben Thompson

No, it was $41 billion.

Andrew Sharp

Okay.

Ben Thompson

$41 billion in 2025. Around the $30 billion mark in the years before that.

Andrew Sharp

Mm-hmm.

Ben Thompson

So even from there, it's like a 67% increase.

Andrew Sharp

Yeah.

Ben Thompson

And the reason—the problem is that TSMC is nervous. Think about this timeline.

Andrew Sharp

It's reasonable to be nervous.

Ben Thompson

Right.

Andrew Sharp

Yeah.

Ben Thompson

If the bubble bursts—say, 2029 is 3 years away. I keep reading this as 2026. The bubble bursts in 2028.

Andrew Sharp

Mm-hmm.

Ben Thompson

You've spent all that money, and you spend money the next year and after that, and suddenly you have fabs with all this equipment you've spent money on, and no one needs or wants the chips.

Andrew Sharp

Yeah.

Ben Thompson

That's the risk of their business—

Andrew Sharp

That's the risk of their business: it's so capital-intensive that if demand ebbs—

Ben Thompson

If you're—

Andrew Sharp

—along the way.

Ben Thompson

You're either extremely profitable or you're just not profitable at all. It's a big—

Andrew Sharp

That's what I meant—

Ben Thompson

No, you're going bankrupt.

Andrew Sharp

—with even being underwater. You could really struggle—

Ben Thompson

Exactly.

Andrew Sharp

—in dollar years.

Ben Thompson

But the issue is that TSMC is trying to reduce that risk.

Andrew Sharp

Mm-hmm.

Ben Thompson

Risk doesn't disappear from the system. That risk is being offloaded to TSMC's customers.

Andrew Sharp

How so?

Ben Thompson

Whether that be NVIDIA or Microsoft or Google or whoever it might be. What does every single CEO say on their earnings call?

Andrew Sharp

I don't know. I don't listen to nearly as many earnings calls as you do.

Ben Thompson

They say, "If we had more capacity, we would've sold more."

Andrew Sharp

Mm-hmm.

Ben Thompson

The risk that TSMC is offsetting is foregone revenue for all these companies. All these companies are realizing that risk right now. On every earnings call, when a CEO's on there saying, "Demand vastly exceeds supply," what that is is foregone revenue. That revenue's gone forever, and that revenue is downstream from TSMC not having enough capacity.

Andrew Sharp

Right. Well, and so, is TSMC, by themselves, gating the AI infrastructure build-out—the bubbling conditions?

Ben Thompson

Yes.

Andrew Sharp

Mm-hmm.

Ben Thompson

This is why I called it the TSMC brake. I came up with that last year. I should've written a big article. Maybe I'll write a big article. I think they are the brake on an AI bubble, on AI generally.

Andrew Sharp

Right.

Andrew Sharp

Well, no, when you wrote it last year, it didn't fully register with me. Then I read it earlier this week, and I was like, "Oh, he's making a play on accelerationists and TSMC. They're the ones that are the brakes in the middle of all this." It really is fascinating when you step back and look at the ecosystem and think about how much crazier the numbers could be if TSMC could serve the capacity in the middle of all of it.

Ben Thompson

That's exactly right. So the issue is that all these folks think they're de-risking by sticking with TSMC.

Andrew Sharp

Mm-hmm.

Ben Thompson

Because it's the known entity, they have good customer service, and they have confidence it's going to work.

Andrew Sharp

But there's a ceiling on how much they can produce—

Ben Thompson

They have been—

Andrew Sharp

And a ceiling on how much you can make.

Ben Thompson

They actually have been loading fab risk onto themselves. That risk they're loading onto themselves is foregone revenue.

Andrew Sharp

Mm-hmm.

Ben Thompson

That foregone revenue is being realized right now. You could imagine that if AI progresses like people think it will, in 2028 and 2029, this mismatch between supply and demand means $52 billion is not nearly enough.

Andrew Sharp

Interesting. Yeah.

Ben Thompson

And so you're actually loading up on risk.

Andrew Sharp

I'm glad you said that because, reading your update earlier in the week—I was reading it early in the morning—I was like, "It seems like Ben thinks that they should be investing a lot more in CapEx build-out than they actually are." It sounds like that was an accurate reading of the subtext of your analysis.

Ben Thompson

I think that TSMC is doing what is right for TSMC.

Andrew Sharp

Okay.

Ben Thompson

And they're able to do what is right for TSMC because they don't have any competition.

Andrew Sharp

There's no competition, yeah.

Ben Thompson

What I think behooves everyone in AI to do is, they have to get Samsung and Intel on board.

Andrew Sharp

Mm. So Intel's not just a charity case in this scenario. Okay.

Ben Thompson

Well, I mean, I think this makes it clearer than ever. I should've made this a big blog article. Maybe I'll write another one. What happens if Intel is a credible alternative, or Samsung is a credible alternative? What becomes TSMC's greater fear? Is it that 5 years from now we might have this overhang, or is it that we're losing business to Intel and Samsung? And we know that once someone switches, it's hard to get them back because of this long sort of cycle.

Andrew Sharp

And right now the risk to TSMC of underinvesting in CapEx build-out is, "Okay, we're going to make less profit in 3 or 4 years than we might have otherwise, but we're offsetting that risk against tremendous downside risks if the bubble bursts. So we're happy splitting the difference with a 67% increase as opposed to a 167% increase." That's their logic and the way they view this. Is that right?

Ben Thompson

That's right.

Andrew Sharp

But that calculus changes if—

Ben Thompson

What they're doing is offloading risk onto their customers, right?

Andrew Sharp

And there's a much bigger risk if they get 5 or 6 years down the line and half of their customer base is working with other competitors.

Ben Thompson

Well, what you want if you're Google, Microsoft, Amazon, OpenAI, or Anthropic is cheap chips. The way you get cheap chips is by there being too much capacity and them having to sell it at very low prices. The way you get more capacity is by having everyone overbuild. You want overbuilding. You want TSMC facing—

Andrew Sharp

That's why Sam flew to Taiwan.

Ben Thompson

No, Sam's totally wrong.

Andrew Sharp

Oh.

Ben Thompson

I interviewed Sam in the fall and pushed him on this: "You need to be exploring Intel." And he doesn't want to do that because everyone's a little scared of TSMC—because TSMC has limited supply.

Andrew Sharp

They have limited capacity—

Ben Thompson

They get to choose—

Andrew Sharp

... who... That's right.

Andrew Sharp

Yeah.

Ben Thompson

That's right.

Ben Thompson

But the problem is that you're enabling the brake.

Andrew Sharp

Mm.

Ben Thompson

It's the brake—the slowdown.

Andrew Sharp

Yeah.

Ben Thompson

The issue is that Intel and Samsung aren't going to get there without customers actually going for it with them. They need this customer base. The reason to do it is that it shifts the risk back to the foundries. You want the foundries taking risk. You want them building for a huge explosion. The worst-case scenario is that you get super cheap chips because they built too much capacity. That's a good situation.

Andrew Sharp

Mm-hmm.

Ben Thompson

And you're not going to get there. All these companies need to sack up and stop playing—

Andrew Sharp

And the clear-eyed recognition would be that TSMC is just not going to go that direction—

—unless they're forced to.

Ben Thompson

It's kind of pathetic. You're flying to TSMC and begging them to put their business a little bit more at risk for your sake. No. What you need to do is go out and empower and enable an actual competitor for TSMC. That's how you get more TSMC volume. And, by the way, when that competitor comes online, there's more volume for everyone. That means lower prices. That means you can actually start creating chips, your capital costs are lower, and you can avoid these insane bills that all these companies have.

Andrew Sharp

This is great stuff. You really should have made that update public.

Ben Thompson

Yes.

Andrew Sharp

Bad job by you.

Ben Thompson

Yeah. I'll let it go on Monday.

Andrew Sharp

Well, I have 1 question on TSMC, big picture, and potential risks that they incur in the midst of all this. How much of their revenue comes from 3 customers at this point? It's NVIDIA, Apple, and—

Ben Thompson

AMD.

Andrew Sharp

Okay, AMD, and I mean in the AI space.

Ben Thompson

Well, everyone in the world has that at TSMC. Their issue right now is not that they have limited customers; it's that there are too many customers, and people are, by necessity, having to at least consider alternatives.

Andrew Sharp

Mm-hmm.

Ben Thompson

Because there's not enough capacity. There are 2 parts to this. Number 1, they don't want to raise prices too high because people could leave, but they also need to have enough capacity so that people don't leave because they can't get leading-edge chips.

Andrew Sharp

Get what they need.

Ben Thompson

Right.

Andrew Sharp

Yeah.

Ben Thompson

The issue is that all these folks who claim to be big capitalists are being chickens. They're not taking the risk of trying to get an Intel fab going, to get a Samsung fab going, because they're thinking about their short-term risk: What if it's expensive? What if it doesn't work? What if there's a delay? All these sorts of things.

Andrew Sharp

And what if TSMC gets upset and starts playing with our supply for the next 3 years?

Ben Thompson

What they're not thinking about is the long term. There is a scenario where no one does this. We get to 2028 or 2029, and what actually ends up bursting the bubble is that there's not enough chip capacity. This entire opportunity is killed off because everyone was being chickens in 2025.

Andrew Sharp

Yeah. Or there's a war. That's—

Ben Thompson

Another reason—

Andrew Sharp

Another omnipresent risk—

Ben Thompson

Another reason to build up alternatives, yes.

Andrew Sharp

—that's been disregarded.

Well, any final thoughts on TSMC before we shift to Netflix here?

Ben Thompson

If you can't get Morris Chang to give them a kick in the rear end and take the risks—

Andrew Sharp

Mm-hmm.

Ben Thompson

—you get sort of Mr. Market.

Andrew Sharp

Yeah.

Ben Thompson

That's the answer. And we'll see. But this is the time now. The time now is to make decisions for 2028 and 2029, and I think tech companies are uncomfortable thinking that far in the future.

Andrew Sharp

Mm-hmm.

Ben Thompson

Even though software obviously takes a long time to build, things like this—meaningful CapEx investments—it's almost like a new muscle for Silicon Valley. You've always been able to assume the hardware is there.

Andrew Sharp

Right.

Ben Thompson

And especially with the rise of the cloud and being able to rent. But there needs to be this development and this increased appetite for risk because you're actually risking more by not thinking about it than you might realize.

Andrew Sharp

You're risking foregoing profits. It's an interesting corner of the space, though, because even for TSMC, it's hard to chart a course for where all of this is going to be and whether the bubble will or won't burst, and whether the demand will or won't be there—

Ben Thompson

Right, but you want to put that risk on the foundries. The way you force TSMC—

Andrew Sharp

—in 4 years.

Well, if you're 1 of the AI companies, of course you do. But it's a fascinating aspect of the whole discussion because they're the ones that really do have to think about the end of the decade as they're making decisions today—TSMC, that is, in addition to—

Ben Thompson

But if you're an AI company, you need to think about the end of the decade too.

Andrew Sharp

Mm-hmm.

Ben Thompson

Because you're going to show up at the end of the decade and not be making nearly as much revenue as—

you could because there weren't enough chips.

Andrew Sharp

Sam Altman in his interview with you is making all these investments today for what demand—

Ben Thompson

He likes—

Andrew Sharp

…will look like in 2028.

Ben Thompson

OpenAI is whining over and over again: “We don’t have enough compute. We don’t have enough compute. We don’t have enough compute.” Well, then—

Andrew Sharp

Or we want to be ready when there’s even more demand than there is today.

Ben Thompson

Right. And—

Andrew Sharp

They’re not taking the steps—

Ben Thompson

Half a hand—

Andrew Sharp

…they need to take.

Ben Thompson

Short-sighted.

Andrew Sharp

Yeah.

Ben Thompson

Yeah.

Andrew Sharp

Yeah.

Ben Thompson

Well, it, it's... Yeah.

Andrew Sharp
