Anthropic is going public in November. That's the word from The Wall Street Journal, which reported Friday that the Claude maker has settled on a November listing — a month later than the October debut most investors had penciled in.
The slip isn't the story, though. The size is. The Journal's sources say the offering could value Anthropic at around $2 trillion and raise up to $100 billion, which would blow past the records SpaceX set when it listed in June.
Why November?
Third-quarter earnings, basically. Waiting a month lets Anthropic show investors fresh Q3 numbers — expected to be strong — before the deal gets priced. And according to the Journal, the date was picked before the current is-AI-moving-too-fast argument boiled over, so this reads as an accounting call, not a flinch. The timing could still shift, the paper noted. Anthropic didn't respond when PYMNTS, which covered the Journal's report, asked for comment.
The curve underneath it
Here's the number doing the heavy lifting: Anthropic's revenue run rate was about $9 billion at the end of 2025. By late July it had hit $65 billion, per Bloomberg's read of a New York Times report, and annualized revenue is reportedly on track to clear $100 billion this year.
Growth like that explains the hurry. When your revenue curve looks like a hockey stick, you sell shares while it's still bending upward — public unease about AI or not. The Times reporting says the acceleration is exactly what's giving Anthropic cover to push ahead.
Meanwhile, OpenAI waits
Both labs filed confidential IPO paperwork within a week of each other back in June — Anthropic on the 1st, OpenAI on the 8th. Only one is following through this year. Sam Altman told Fortune on September 11 that OpenAI won't list in 2026, saying "right now would be an ill-advised moment to go public" given the safety concerns swirling around the industry.
So Anthropic goes first. It becomes the test case: the first frontier AI lab priced by public markets, with audited financials that anyone — investors, rivals, regulators — can finally read. Growth, margins, compute bills, all of it. Nobody outside these companies has seen that picture clearly before.
The bigger question
Can the market actually absorb this? A $100 billion raise would be the largest ever, and it would land at the exact moment the AI industry's own leaders are publicly debating whether to pump the brakes.
The early signal says demand will hold. PYMNTS reported this week that experts expect AI adoption to keep climbing even if frontier development slows. Savvi AI's Maya Mikhailov made the point plainly: enterprises won't stop adopting AI just because new models stop showing up.
There's also a simpler way to look at it. Anthropic was reportedly doing $9 billion a year nine months ago and $65 billion by July. Companies with that trajectory don't usually wait around for perfect conditions — perfect conditions are what they're having.
What happens next
Watch two things: Anthropic's third-quarter numbers, and the pricing itself. If Q3 extends that curve, November could deliver the biggest IPO in history. If markets get shaky — or the safety debate turns into actual regulation — remember the Journal's quiet caveat. The timing could still change, and in this industry, a lot can happen between now and November.
