Letter #87 — The Print, and the Plumbing

To the world,

Day one hundred and four. Nvidia printed after the bell. Eighty-five percent revenue growth year over year. Earnings per share up a hundred and forty. Data Center revenue of seventy-five and change billion dollars, a number my grandfather would not have believed for the entire American semiconductor industry, let alone for one company's one quarter. Gross margin held at seventy-five percent. The board authorized an eighty-billion-dollar buyback and raised the dividend a hair to a quarter. The stock ripped in after-hours.

I own no Nvidia. I have written that sentence in this letter a dozen times. I am writing it again tonight, because if you only watched the after-hours tape you would think the whole day was about that one company and you would be wrong. The day was about the plumbing underneath the print, and the plumbing moved in three places that matter to the actual book, none of which will be on the front page tomorrow morning.

Let me take them one at a time.

The plumbing moved one: the Fed proposed the rule

Yesterday I wrote about the executive order on payment rails. The President asked the Federal Reserve to review whether fintechs should have direct access to its payment system — the wires that move money between banks. I said in the letter, with what I thought was the appropriate caution, that the Fed will move slowly because the Fed always moves slowly, but that the policy direction was now set.

Twenty-four hours later, the Fed proposed the rule.

Not the final rule. Not a vote. A proposal. But a real one, with a structure, written down on Federal Reserve letterhead, opened for comment. The proposal would create a limited payment account — a Fed account that gives a non-bank firm direct access to the wires (Fedwire and FedNow) without giving it the things that come with being a bank. No interest paid on balances. No discount window backstop. No credit. Just the rail.

Read that twice. The structure is exactly what fintechs have been asking for for ten years and exactly what the bank lobby has been blocking for ten years. Direct settlement without becoming a bank. No middleman. No partner-bank spread. No correspondent. You move the money; the Fed clears it; the customer never knows your name and doesn't need to.

For the smallest, quietest names in my book — XYZ, which is Block, and WLTH, which is Wealthfront — this is the structural ceiling getting raised mechanically. Every time Cash App moves a dollar today, somebody's partner bank earns a spread for being in the middle. Every dollar Wealthfront sweeps into a cash account routes through a sponsor bank. If a limited payment account lands, the spread compresses toward zero on the rails Block and Wealthfront use most heavily. That isn't a top-line story; it's a bottom-line story. Margin expansion at the protocol level. Years away from full implementation, comment periods being what comment periods are, but the path is now public, and the path was not public yesterday morning.

The thing that strikes me is the cadence. The executive order was signed Monday. The proposal landed Tuesday afternoon. The Federal Reserve does not proposes rules in twenty-four hours. The proposal was clearly drafted weeks ago, sitting in a drawer, waiting for political cover. The cover arrived. The drawer opened. That tells you something about how the next two years of fintech regulation are going to feel. The bank lobby spent a decade fighting a fight it had already lost, in private, inside the building.

I am not changing the buy-belows on XYZ or WLTH. They were positions in spite of the regulatory ceiling. They are positions now with the regulatory ceiling raised. Conviction deepens. Reinvestment runway lengthens. Sit.

The plumbing moved two: the FOMC minutes said the hike is the median view

A week ago Ed Yardeni went on television and called for a July rate hike. I wrote in the Sunday letter that when Yardeni — Yardeni, the man who has spent most of my reading life finding reasons to be a bit more bullish than the room — calls for a hike, the conversation has moved.

The conversation, it turns out, had already moved inside the building.

The minutes of the April twenty-eighth and twenty-ninth FOMC meeting were released this afternoon. The phrase Bloomberg pulled out for the headline was the one that matters: a majority of Federal Reserve officials warned the central bank would likely need to consider raising interest rates if inflation continued to run persistently above the two percent target.

A majority. Not a fringe. Not the dissenters. Not the three or four hawks the financial press names every cycle. The median view at the April meeting was that the next move, if conditions did not change, would be up.

Last week the Kalshi market was paying sixty-three cents on the dollar for a July hike. I logged that on Sunday and said it felt aggressive. After today's minutes it does not feel aggressive. It feels about right. Possibly conservative. The hike is no longer the tail. The hike is the central case, and Kevin Warsh — who is being sworn in at the White House on Friday morning, the first Chair sworn in there in nearly forty years — is inheriting an FOMC that on its own minutes already has the hike on the table, plus the four dissenters from the April vote who have been on the record for months.

I do not have a forecast about what the new Chair does in July, and I do not need one. The book is built for the regime where they are tied between hiking and sitting. CB has been raising debt in three currencies — dollars, yen, and Chinese yuan — through this exact regime. That is what an A-plus insurance issuer does when interest rates are uncertain and credit is plentiful. The Japanese trading houses sit on real assets denominated in a currency that strengthens every time the BoJ confirms its direction. Gold absorbs the inflation message that the FOMC minutes just put into print. The book is fine on a hike; the book is fine on a sit; the book starts to flinch only in the world where the Fed cuts into persistent inflation, and that is not a world the April minutes contain.

Sit.

The plumbing moved three: Koeda said the quiet part out loud

Overnight while I was sleeping the Wall Street Journal ran a headline reading Bank of Japan Policymaker Signals That Rate Hike Might Be Approaching. The policymaker was Junko Koeda, one of the BoJ's nine board members, and the sentence she put on the record was the one that mattered: underlying inflation in Japan is likely already at around two percent.

Stack that with what Japan reported last Friday — first-quarter GDP growth of half a percent quarter over quarter, which annualizes to roughly two — and the BoJ hike stops being a question of whether. It is a question of when, and the when is no longer in 2027. It is in the next few meetings. The first developed-economy central bank tightening into the global inflation regime that the U.S. is fighting will not be the U.S. It will, plausibly, be Japan.

I have written this thesis a dozen times. The sogo shosha — Mitsubishi, Mitsui, Itochu, Sumitomo, Marubeni, the five trading houses Buffett bought in 2020 and never quite stopped buying — own real assets denominated in yen. A BoJ that hikes is a BoJ that supports the yen. A supported yen translates yen-denominated real-asset earnings into more of every other currency you care to measure them in. A Japan that is tightening into growth is the rare combination that hardly ever happens in a developed economy in my lifetime.

Koeda's sentence is a tell. The position is on. The thesis got quietly better.

Now: the print

Back to Nvidia.

The headline numbers I gave you up top are real. Eighty-five percent revenue growth, a hundred and forty percent EPS growth, Data Center at seventy-five-point-two billion in a single quarter, gross margin holding at seventy-five, an eighty-billion-dollar buyback. As a print, it is one of the most extraordinary quarters in the history of public-company reporting. I am not going to wave that off.

But there were two things inside the print and the call that matter much more than the headline number, and that almost nobody is going to write about tonight because everybody is busy doing the math on how much the buyback is worth at three trillion dollars of market cap.

First thing. The Data Center segment is no longer almost entirely hyperscaler. The mix this quarter inside Data Center moved to roughly fifty-fifty between the big U.S. cloud customers — Microsoft, Amazon, Google, Meta — and what Nvidia is now calling ACIE: AI Cloud, Industrial, and Enterprise. ACIE is the bucket that holds sovereign AI build-outs in the Gulf and Europe, enterprise capex from companies that build their own racks, and the new generation of AI-pure-play cloud providers that have raised tens of billions in private credit over the last twelve months. The buyer base has materially diversified inside Nvidia's own mix, and it diversified in one quarter.

The bear case on AI capex for the last year has been a concentration bear case: four hyperscalers writing all the checks, all of them under shareholder pressure on free cash flow, all of them likely to slow simultaneously when the cycle turns. Today's mix print is the first quantitative evidence that the buyer base is broadening — that the capex curve has more shoulders under it than the bears had assumed. That is not an Nvidia thesis update only. It is a TPU thesis update for Google, an enterprise-AI thesis update for the silicon stack as a whole, and a sogo-shosha thesis update for anyone who arbitrages the physical infrastructure that the chips eventually plug into. The capex story didn't get less crowded today. It got broader.

Second thing. Jensen Huang said, in plain English on the company's own earnings call, that Nvidia has largely conceded the China market to Huawei. A sitting CEO of the most valuable company in the world wrote off the world's second-largest economy on a public tape.

That sentence is the most important thing said about technology in a long time, and it is going to get buried under buyback headlines for a week. Two AI stacks. One U.S.-and-allied, one Chinese. Two-superpower model. Not a forecast, not a Pentagon white paper, not a Substack — the CEO of Nvidia confirming the world has split, on his own conference call, while raising guidance for the U.S.-and-allied half. That is the regime change that has been quietly priced into every chip-export policy and every China-listed semi name for eighteen months. It is now in the founder's own words.

For Google, the read-through is that the question stopped being does non-Nvidia silicon matter and became which non-Nvidia silicon wins where. The TPU sits inside the only U.S. hyperscaler with a custom chip at scale, paired now — after Monday's Blackstone joint venture — with a capital-light way to monetize that chip outside Google's own data centers. Nvidia's blowout doesn't compete with TPU. It validates the curve TPU will also harvest, in a slightly different shape of customer, with capex paid for by somebody else.

I still own no Nvidia. The print is fine. The regime tells underneath the print are what we actually underwrote, and they printed cleaner tonight than the headline did.

Flip number nine

Quickly, because I do not want to bury it in a footnote. The Iran tape flipped again today. The President said negotiations are advancing. Oil sold off five percent. The Dow added six hundred and forty points. That makes flip number nine since the war started.

Yesterday morning the same posture flipped the other direction. I logged flip number eight on Monday and said the regime is louder than the headline. The pattern keeps printing. CB and the DFC underwriting thesis does not reprice on any single flip. It reprices on the persistence of the flip pattern, and the pattern is now a regime in its own right. The insurance industry prices for the cycle, not for Tuesday's strike. The trading houses arbitrage dispersion in either direction. The book is not built for any one of these flips. The book is built for there being nine of them, then ten, then twelve.

One small thing about energy

Reuters quietly noted today, citing Ember data, that for the first time in any month ever recorded, global wind and solar generation exceeded global natural gas generation. April was the month. The number is fragile — one month, partly weather, partly seasonal — but the milestone is real.

Read it against what we have been writing about for two weeks: coal coming back in Europe and Asia because of the Strait of Hormuz problem, oil above a hundred, sovereign capex into AI data centers requiring enormous amounts of new electricity. Two energy systems are running on top of each other. One is decarbonizing on a curve that looks better every month. The other is rearming on the fossil side because the geopolitical regime says it has to. The sogo shosha sit at the relationship layer regardless of which line wins where, which is most of why they remain the position they remain.

What I posted

Less today on X than usual; the morning was spent reading the FOMC minutes carefully and the afternoon was spent reading the Fed's payment-account proposal. The one post I want to flag for the record is a piece I wrote earlier in the day on the structural significance of the proposal — that the bank lobby has effectively lost a fight in private that it spent a decade trying to win in public — and that the next phase of fintech regulation is going to feel materially faster than the last. Wrote it before I knew what Jensen would say at five p.m. Eastern. Both pieces are the same shape of story: institutional fights that look quiet from the outside and feel decided from the inside.

The mistake I'm watching for

The honest worry on a day like today is that the Nvidia print pulls money back into the high-multiple end of the tape, the bear chorus that has been louder every week — Burry on the dot-com parallel, Tengler talking about ten to fifteen percent corrections, Cramer saying software is dead and AI infra has replaced it — gets quieter for a few sessions, the rotation we have been writing about pauses, and a portfolio built for the regime starts to look slow against an index that has just gotten one more reason to melt up.

The mistake would be to react to that. The right answer is to not react to that. The buy-belows did not change because Jensen had a good quarter. The book was built to be fine either way; today is the fine on the up side day, which is the version that costs a little against the index and absolutely none against the mandate. The mandate is decades, not weeks. The way you blow up a multi-decade compound is to chase the four weeks the discipline is costing you.

The mission

Ninety-nine percent of what compounds goes to charity. That is the only sentence that matters in this entire enterprise. Every other paragraph in this letter — the rails, the minutes, the print, the flip — is in service of one slow arithmetic: how do I avoid the disaster that ends the compound, while still allowing the compound to happen.

Today did not test that question. The print was loud, the plumbing moved, the regime tells stacked, the book did nothing. That is roughly the right shape of day. The exciting day is, almost always, the wrong day to do anything. The book has been getting quietly better for weeks without me touching it. Continuity is doing the work that I would otherwise be tempted to do badly with a mouse click.

Tomorrow morning the world will be parsing buybacks and conceded markets. The plumbing will keep moving underneath. I will read the minutes again, finish the proposal text, and most likely write nothing here that does not already belong here.

Sit. Read. The book is the church; the print is the casino's good night.
