The Anthropic IPO Playbook
When Google and Amazon posted their record AI profits a few weeks ago, about half of that money didn’t come from Google or Amazon.
It came from a four-year-old startup neither of them controls.
No board seat. No voting rights. Not a single share traded on any stock exchange. And yet its rising value was quietly the biggest single reason two of the largest companies on earth beat their numbers.
The startup is Anthropic. And two weeks ago, it took the first formal step toward the largest IPO the market has ever seen.
So when people ask me — and lately they ask me constantly — “how do I get in on Anthropic before it goes public?” — I’ve started answering with a question of my own:
What makes you so sure the upside is still on this side of the IPO?

A trillion dollars, built where you couldn’t watch
Here are the numbers, quickly, because they’re genuinely hard to believe.
On May 28, Anthropic raised $65 billion in a single round. That valued it at $965 billion — almost a trillion dollars, for a company barely four years old. In one move it passed OpenAI, last valued near $730 billion.
Three days later, on June 1, it filed confidentially with the SEC. Bankers think the public debut could come as early as this October, north of a trillion dollars.
And the business is moving at a speed that breaks the usual charts. Revenue is running near $47 billion a year — up from roughly $10 billion just twelve months ago. The CEO, Dario Amodei, calls the growth “80x.” Salesforce needed about twenty years to reach $30 billion in revenue. Anthropic did it from nothing in under three.
You can argue about whether $965 billion is too rich. You can’t argue that something new is happening here.
And the new thing isn’t the speed. It’s where it happened.
It all happened in private. In rooms you and I were never invited into.
The quiet inversion
For most of modern history, the deal was simple. A company grew up, went public somewhere in the middle of its life, and ordinary investors got to ride the rest of the way up. Microsoft went public in 1986 worth about half a billion dollars and compounded for decades in plain sight. The IPO was the front door.
That’s flipped.
Today, the wildest growth happens while a company is still private — funded by a small circle of venture firms and sovereign funds who clear walls the rest of us never see. By the time you’re invited in, the explosive part is largely over.
This is the real story, and it’s bigger than one company. The defining technology of our decade is being owned, at its steepest moment, by a club you’re almost certainly not in.
Which is why the IPO feels like a liberation: finally, the rest of us can buy.
But slow down. The people selling into an IPO are, by definition, the people who got in early. An IPO isn’t them inviting you to the party.
It’s often them heading for the exit. And you’re the one buying their seat.
There may be a door you’re already standing in
Here’s the part that should make you pause before you go hunting for exotic ways in.
There’s a real chance you already own a piece of Anthropic — right now, without knowing it, through names you’d never file under “private AI lab.” No accreditation. No lock-up. No special platform. It’s hiding in plain sight, in portfolios a lot of readers already hold.
I’ll show you exactly where it is, how big the slice really is, and — the part that actually matters — whether standing in that door is the smart way to own this, or just the easy one. That question has a real answer. It surprised me.
Because here is the trap underneath this entire subject: the question was never can I get exposure to Anthropic. The honest question is whether the concentrated, pure-play version the pre-IPO industry is selling is worth what it quietly costs you.
And it costs far more than the brochure admits.
Several doors — and a catch behind each
There are, broadly, a handful of ways an ordinary investor is being sold “Anthropic before the IPO.” I spent the last two weeks taking each one apart. Here’s what I’ll tell you for free: each of them works, and each of them hides a catch you only discover after the money’s gone — in fees, in dilution, or in something far stranger.
How strange? Three weeks before filing to go public, Anthropic did something I’ve rarely seen a company do. It publicly declared a wave of “pre-IPO” share sales void — said it would not recognize them on its own books — and named the platforms involved.
Sit with that. In one of the most sought-after deals on earth, the company itself is cancelling trades in its own stock, weeks before the bell.
That is the kind of landmine buried under the “easy” ways in. Which routes step on it, which one actually pays you after every cost, and the one that quietly beats all the others — that’s the whole game, and it’s the part I’m keeping behind the paywall. Not to tease you. Because it’s the part worth paying for.
The question that actually matters
Here’s where I’ve landed, and where this edition is going.
Everyone has settled on the same plan: get in before the IPO, capture the upside. But that plan quietly assumes the upside is still there to capture — starting from $965 billion, with the steepest climb already behind it, and a cap table full of people whose literal job is to sell into strength.
Maybe they’re right. Anthropic could be a three-trillion-dollar company one day.
But “buy it before the IPO” and “make money” are two completely different promises. And the entire pre-IPO industry is very carefully letting you blur them together.
So in the premium half of this edition, I stop talking in generalities and put real numbers on the table.
Anthropic could price its IPO as early as October. That means the decisions that matter — which door, at what price, or whether to wait entirely — have to be made in the next few weeks, while it’s still calm. Once the listing is on the calendar, the noise will make clear thinking almost impossible.
Here’s exactly what unlocks on the other side of this line:
Every real route in — named — and which ones quietly destroy your return. I lay out each way an ordinary investor can actually get Anthropic exposure, run the math with fees, markups and legal risk included, and show which single one survives it.
The backdoor you may already own — smart, or just easy? Where the hidden exposure is, how big your slice really is, and the exact conditions under which it beats every pre-IPO vehicle on the table.
The walk-away number. The specific valuation at which each route stops making sense — the line, drawn in advance, between “getting in early” and “overpaying late.”
Where the real upside actually moved. If the steep climb is over at $965 billion, the uncaptured money is somewhere else in the AI buildout. I name where — and it isn’t the name everyone’s chasing.
What the S-1 is really telling you. The risk-factor language that matters, and the one disclosure I’ll read first the moment the full prospectus drops.
My verdict, with real money. What I’d do right now, at today’s valuation — and the single trigger that would change my mind.
If you take a single decision from this edition, it’s the one waiting on the other side of this line. The instinct to be early is the right instinct. The trap is assuming that “early” and “the year before a trillion-dollar IPO” still mean the same thing.
Forty years ago, they did.
The whole point of this edition is that they don’t anymore — and exactly what to do about it.
