Anthropic just dropped a confidential S-1 with the SEC. The valuation on the filing: $965 billion. If the company goes public at that number — and everything about this filing suggests it will — Anthropic will surpass OpenAI, Stripe, SpaceX, and every other private-turned-public tech company in history on day one. The target date is October 23, 2026, and the underwriters are already circling.
Let that sink in for a second. This is a company that didn’t exist four years ago. A company founded by two people who walked away from OpenAI because they thought Sam Altman was moving too fast. And now Dario Amodei’s safety-first bet is about to be worth nearly a trillion dollars — more than the company he left behind.
The Numbers That Made Wall Street Lose Its Mind
Here’s why every bank on the Street is fighting for a piece of this deal. Anthropic’s run-rate revenue as of May 2026 sits at approximately $47 billion. That’s not a typo. At the end of 2025, the company was doing $10 billion annually. In less than a year, revenue grew by roughly 370%.
And here’s the part that changes the math entirely: Anthropic expects to post its first operating profit — approximately $559 million — in Q2 2026. For context, OpenAI is still burning cash at a pace that makes WeWork look disciplined. Anthropic just proved that you can build frontier AI models and make money doing it. That’s the difference between a company that files an IPO and a company that needs one.
From $900 Billion to $965 Billion in Eight Days
Eight days ago, Anthropic closed a $65 billion funding round at a $900 billion valuation — already the largest private funding round in technology history. But the S-1 filing pegs the valuation at $965 billion. That $65 billion jump in eight days isn’t momentum. It’s demand. The round was so oversubscribed that Anthropic could ratchet up the number before even going public.
Think of it like this: Anthropic raised more money in its last private round than most countries spend on defense. And then the public markets looked at that number and said, we’ll pay more.
Why This IPO Is Different From OpenAI’s
OpenAI filed its IPO paperwork in late May at an $850 billion valuation. On paper, that’s a smaller company. But the real gap isn’t in the valuation — it’s in the trajectory. OpenAI is still bleeding money, still fighting a public lawsuit with Elon Musk (which it just won), still dealing with executive departures, and still trying to convince the world that ads inside ChatGPT are a viable business model.
Anthropic, meanwhile, has a locked-in $100 billion AWS contract with Amazon, a business that’s actually profitable, and a product — Claude — that enterprise customers are paying real money for. The company doesn’t need to go public to survive. It’s going public because the private market literally can’t hold this much value anymore.
That’s the key distinction. OpenAI’s IPO reads like a necessity. Anthropic’s reads like a victory lap.
The Amazon Factor Nobody’s Pricing In
Here’s the part of this story that doesn’t get enough attention. Amazon has committed over $100 billion to Anthropic through a combination of direct investment and AWS compute contracts. That makes Amazon both Anthropic’s largest investor and its biggest customer. When Anthropic goes public, Amazon’s stake could be worth more than its entire Whole Foods acquisition — several times over.
But there’s a second-order effect here. Every enterprise running on AWS now has native access to Claude. That’s not a feature — it’s a distribution moat. OpenAI is available on Azure. Anthropic is available on AWS, Google Cloud, and directly. The multi-cloud strategy means Anthropic doesn’t have a single-vendor dependency. OpenAI does. At nearly a trillion dollars, the market is pricing in that difference.
What $965 Billion Actually Means
If Anthropic lists at this valuation, it would immediately rank among the top 15 most valuable companies on the S&P 500. It would be worth more than JPMorgan, more than Visa, more than Johnson & Johnson. A four-year-old AI company sitting next to banks and pharmaceutical giants that took a century to build.
The filing was submitted under the SEC’s confidential review process, which means we won’t see the full S-1 — the revenue breakdown, the risk factors, the cap table — for weeks. But the number that matters is already out. And it starts with a nine and ends with eleven zeroes.
The Verdict: Safety Sells
Dario Amodei left OpenAI because he believed the company was cutting corners on safety. He founded Anthropic on the premise that you could build powerful AI responsibly and still make money. Wall Street just put a price on that thesis: $965 billion.
The irony is almost too perfect. The company that left OpenAI over principle is now worth more than OpenAI. The company that insisted on slower, more careful development is growing faster than anyone in the industry. The company that bet on safety is about to become the most valuable IPO in technology history.
Every founder who ever got told that “responsible AI” was a competitive disadvantage should bookmark this filing. The market just proved them wrong — to the tune of a trillion dollars.
