The $3 Trillion Quarter
On April 1, 2026, around midnight New York time, twenty-one banks hung up simultaneously after a conference call that left them with heavy shoulders. Morgan Stanley, Goldman Sachs, JPMorgan, Bank of America, Citigroup as leads. Sixteen others in supporting roles. Twenty-one banks for a single IPO — that’s almost unprecedented. Most of the historic mega-IPOs mobilized three to five.
They’re working on a deal with a codename: Project Apex.
What they’re preparing is the public listing of SpaceX. Target valuation: $1.75 trillion. Raise: $75 billion. And here, I want you to pause for a second. Because that number, “75 billion,” slides right off the page when you write it. But it’s 2.5 times what Saudi Aramco raised in 2019. Aramco, at the time, was already considered the largest IPO in human history. Not of the year. Not of the decade. Of humanity.
SpaceX is preparing to do it 2.5 times bigger.
And here’s why I’m writing this edition today: SpaceX isn’t the event. It’s just the opening scene.
In September, Anthropic files its S-1. Listing target October, valuation $400-500 billion, raise $60 billion minimum. In Q4, OpenAI follows. Target $1 trillion. Raise probably $30-50 billion.
Add it up. Three trillion dollars of market cap hitting public markets in six months. For scale: the entire US IPO market raised $469 billion across the whole decade from 2016 to 2025. PitchBook estimates the 2026 cohort alone will need to absorb between $432 and $576 billion in a single quarter. More than the entire prior decade. In 90 days.
And while all this is being prepared behind the scenes, in Omaha, last Saturday May 2, a 95-year-old man sat in the audience of his own annual meeting for the first time in sixty years. Warren Buffett no longer runs Berkshire but remains chairman. And when he was asked why his company has accumulated $397.4 billion in cash — the largest corporate cash pile ever assembled in history — he leaned into his microphone and said:
“The market feels like a church with a casino attached. We’ve never had people in a more gambling mood than now.”
Buffett isn’t predicting a crash. He’s doing something more subtle. He’s positioning for one. And he isn’t alone.
The thing nobody is telling you
OK, here’s where I want us to go together.
Almost every analysis you’ll read about these IPOs frames the topic as a question of personal investment. Should I buy SpaceX at the IPO? Is Anthropic overvalued? Can OpenAI hold a trillion? These are fine questions for your portfolio. But they’re not the question.
Here’s the real question, and it’s pure macro: where is the money going to come from?
Because SpaceX, OpenAI, and Anthropic don’t create capital when they go public. They redirect it. Every dollar that buys an Anthropic share is a dollar that left somewhere else. Every institutional allocation toward OpenAI is a rebalancing that empties another pocket of the portfolio. And by the way — hold onto your seat for this one — Reuters reports that Elon wants to reserve up to 30% of the SpaceX IPO for retail investors. Unheard of. Standard retail allocation on a deal this size is 5-10%. Here we’re talking about mobilizing tens of billions of dollars from household savings, largely funded by selling other positions those households already hold.
Now add two things commentators systematically ignore:
The US Treasury needs to issue more than $2 trillion in net new debt over the next twelve months. The fiscal deficit is running at 6-7% of GDP. That debt is drawing from the same global liquidity pool as SpaceX and OpenAI. The Treasury and Elon are negotiating — without speaking to each other — for the same wallets.
Nasdaq just passed a new rule, “Fast Entry,” effective May 1. Mega-IPOs can now join the Nasdaq-100 after just 15 trading days, instead of the historical one-year wait. S&P Dow Jones is considering the same thing for the S&P 500, at six months. You see where I’m going with this? When SpaceX enters the Nasdaq-100 in mid-July, every passive fund tracking the index has to buy SpaceX. Mechanically. Without thinking. And to buy, they sell other index positions, proportionally. So Apple, Microsoft, Nvidia get trimmed at the margin — not because their fundamentals changed, but because room had to be made.
There. That’s what Buffett was describing when he said “casino attached.” Not that the companies themselves are casinos — Starlink has 10 million subscribers, Anthropic just passed OpenAI at $30 billion in ARR, these are real businesses. The casino is the mechanism through which the system absorbs these IPOs.
Ultra-low float (2-5% of equity listed instead of the historical 15-25%) → artificial scarcity → first-day pop → “successful IPO” headlines → retail FOMO → and then 12 months later, the lock-up expires and 95% of the company suddenly becomes tradable in a short window. PitchBook puts the potential sell pressure from the 2026 cohort at $1.4 to $1.6 trillion within 12 months of listing.
You see the trap? The IPO itself isn’t the risk. It’s what comes after.
My thesis, no hedge
Here’s what I really think, and it’s why I’m writing this edition today rather than two months from now.
The current market isn’t concentrated. It’s fragile. The top 10 stocks of the S&P 500 weigh 40.7% of the index. That’s an absolute record, higher than the dot-com peak of 2000. The Shiller CAPE ratio sits at 39.4 — a level previously reached just before the 2000 crash. The effective N of the index (the equivalent number of equally-weighted stocks) has dropped below 54. You think you own an index of 503 stocks? You own 54 bets.
Now add SpaceX, Anthropic, and OpenAI to that basket over six months. What do you do? You add three new monumental bets, all on the same thesis (AI, or AI-adjacent in SpaceX’s case via xAI). In total, 96% of the 2026 IPO pipeline by valuation is exposed to AI. We’re not diversifying. We’re amplifying.
And what really worries me isn’t that the market is going up. It probably will go up, at least at first. What worries me is what happens in the rest of the market while it goes up. The capital fleeing toward those three IPOs doesn’t come back to profitable mid-caps, to emerging markets, to European equities, to non-tech investment-grade credit. Everything outside the top twenty market caps is going to slowly drain. Not in a crash — just in a drying out.
And when the first lock-up expires — around June 2027 for SpaceX — we’re going to discover that the liquidity pulled from everywhere to absorb these IPOs hasn’t come back. The market will be more concentrated, more passive, more mechanical, and more fragile than it is today.
The parallel that haunts me: 2000. Not for the easy “tech bubble that pops” analogy. For something more precise. In 2000, the top 10 stocks represented 23% of the S&P. Today: 40.7%. The one factor that makes today look better than 2000 is that fundamentals are stronger — the Mag-7 are massively profitable, which Cisco and Nortel were not. But the market structure is more extreme than back then. Lower float, more passive dominance, higher concentration. The fragility isn’t in the companies. It’s in the plumbing.
Buffett knows this. That’s why he’s sitting on $400 billion in cash. He’s waiting for a fuse to blow so he can buy what gets violently sold when one fund — maybe just one — needs to derisk in a hurry.
What you should be asking yourself this week
Honestly? If you’re not a professional investor, I’m not telling you to “sell everything.” Far from it. I’m telling you to understand what’s happening, because it’s going to reshape your investments for years without you noticing.
Three questions you should be asking now, not three months from now:
First, your passive allocation. If you hold an S&P 500 or Nasdaq ETF, you’re going to mechanically buy SpaceX, Anthropic, and OpenAI in the weeks following each IPO, at inclusion prices that will be near peak sentiment. You decided nothing. The system decided for you. Are you OK with that?
Second, your exposure to the rest of the market. Which sectors are not in the Mag-7 and not in the 2026 pipeline, and at risk of suffering from a capital drain? Do you own any? Do you want to? These might be the most asymmetric bets of the next 18 months — precisely because everyone is looking elsewhere.
Third, the calendar. SpaceX roadshow week of June 8. Retail event June 11. Pricing likely right after. You have four weeks before the machine starts turning. That’s not much.

Here’s what I’ve put together for subscribers. Concrete stuff, no commentary:
→ The capital flow map — where the money funding these IPOs is actually coming from, which assets are getting sold to fund them, and where rotation is already happening (I have data that hasn’t surfaced in the press yet).
→ The cliff calendar — exact lock-up expiration dates for each IPO, projected sell-pressure volumes, and the weeks where volatility is going to spike.
→ The index-inclusion arithmetic — which Nasdaq-100 and S&P 500 names are going to get mechanically sold by passive funds to make room. Tickers, weights, dates.
→ The four under-priced sectors I’ve identified as asymmetric bets over 18 months — and why they’ll benefit precisely from the fact that everyone is looking the other way.
→ The Buffett mechanic — how to build a Berkshire-style optionality posture without sitting in cash for a decade. Concrete instruments, allocation percentages, deployment conditions.
→ The daily dashboard — the 9 leading indicators I personally track (lock-up countdown, Oracle CDS, float ratios, Buffett Indicator, secondary-market pricing on Forge and Hiive, etc.) to anticipate the turn.
