Anthropic wants out of private.
Or at least, they are looking for the exit door.
Monday morning, the AI developer submitted a confidential Form S-1 to the SEC. It is the standard prelude to an IPO. The company hasn’t set a share count. No price target either. Just a vague nod to “market conditions.”
Why now?
The cash burn is getting loud.
The Big Three
It feels like a relay race.
Anthropic, SpaceX, and OpenAI. Three giants, three trillion-dollar dreams, all eyeing the public market in the same year. Elon Musk’s conglomerate—yes, the one that includes Starlink and that social network with the X logo—filed in May. OpenAI is reportedly next in line.
And then there’s Claude’s maker, trying to beat them to the punch.
Their valuations are, at this point… so high that it’s becoming incredibly impractical to raise more capital privately.
Ed Zitron gets it.
The private pool is full. Investors want liquidity. They want to cash out. Keeping the books closed only works if the hype train stays moving fast enough to ignore the physics.
But AI isn’t free.
The hardware costs are staggering. The electricity bills alone could power a small city. You cannot sustain a deficit on faith alone.
Not forever.
Revenue? Or Illusion?
Here is the ugly part.
The AI sector spends roughly two dollars for every dollar it earns back.
Only Nvidia is making real money. Everyone else is digging a hole.
Critics say the accounting is dressed up. “Annualized” revenue figures. Hidden costs. Margins that don’t exist on paper but sure look pretty in the pitch deck.
Anthropic raised $65 billion last week. Their valuation? $965 billion.
It’s insane.
Rob Lalka, who teaches business at Tulane, called it eye-popping.
They spent it just as fast as they got it.
So what happens next?
A public listing allows pension funds and insurance giants to buy in.
Not just day traders on their phones. Real, sticky, boring capital.
That capital comes with strings.
The Accountability Trap
The SEC wants receipts.
The confidential filing hides the details for now, but that changes quickly. Expect a prospectus in a few weeks.
When that document goes live, it will be brutal.
Financials. Risks. Legal liabilities.
Dario Amodei won’t be able to whisper answers in a back room anymore.
He’ll face analysts.
He’ll have quarterly earnings calls.
Sam Altman will too.
Does the market care if you’re profitable?
Meta lost billions on the Metaverse. Investors shrugged.
Maybe they will shrug at AI.
But history suggests otherwise.
Look at Uber.
They bled for years before stabilizing. If Anthropic does the same, shareholders might get twitchy. They’ll demand focus. Less Sora video apps. More revenue-generating tools.
Or maybe it’s a beauty contest.
People buy the stock not because it’s worth it, but because they think you think it’s worth it.
Patrick Corrigan warns of a “momentum crash.”
Prices rise on sheer adrenaline. Then reality hits.
There’s a WeWork comparison floating around.
A 2019 filing that exposed the rot underneath the glossy slides. The IPO collapsed.
Anthropic’s economics aren’t identical, but the principle stands.
If the bubble pops, it pops hard.
The alternative is a quiet death. Delisting from the Nasdaq. Becoming a niche tool. Getting eaten by Microsoft or Google.
Who wins?
No one knows.
The filing sits there, confidential and quiet.
For now, the party continues.
