Anthropic has overtaken OpenAI on paper, with a fresh fundraising round valuing the Claude maker at $965 billion post-money. OpenAI’s latest public valuation sits at $852 billion, which means the private leaderboard has flipped, at least until the next round, the next filing, or the next very expensive burst of investor enthusiasm.
That headline is doing a lot of work. Both companies are still private, both rely on giant funding cycles rather than public market pricing, and both are being judged as much by narrative as by earnings. In other words: this is less a clean finish line than a moving target with venture capital attached.
How Anthropic got ahead in the private valuation race
Anthropic said the new round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital. The company also says its business has benefited from a surge in enterprise customers, which helped fuel a sharp revenue jump around the start of 2026.
The timing matters. OpenAI’s most recent valuation was tied to a round from two months earlier, so the gap is not exactly a clean sprint. This is the sort of private-company race where one side can look ahead simply because it has crossed the line a little later with a fatter check.
Profit claims meet massive spending
Anthropic has also been leaning on a more flattering financial narrative, saying it recently turned an operating profit for one quarter. That still comes with plenty of caveats: the reporting leaves room for accounting questions, and the company’s spending plans remain enormous.
- Hundreds of billions of dollars committed to Amazon, Google, and Broadcom over the next decade
- $1.5 billion per month committed to SpaceX for the short term
- Heavy compute demand that could keep profitability shaky
That combination is familiar across the AI sector: booming demand, brutal infrastructure costs, and investors pretending those two things are naturally compatible forever. They may be for a while. They may also become a very expensive problem the moment growth slows.
Private valuations are a slippery scoreboard
There are already signs that the market has been treating Anthropic as the hotter name. Secondary-share pricing on Forge Global reportedly put Anthropic ahead of OpenAI last month, and prediction markets have also leaned in that direction. But those are still estimates built on fragments, not the kind of transparent pricing that public markets provide.
That may change soon. Reports have said OpenAI is preparing an IPO filing, and Anthropic has also been linked to a possible public debut later in the year. Once both companies are trading openly, the ”who’s worth more?” debate gets a lot less theatrical and a lot more literal.
What happens if both companies go public
If the listings happen, the comparison stops being a venture-capital parlor game and turns into an everyday stock price battle. That could also expose a harder truth for the whole AI sector: investors may love the promise of foundation models, but they are going to want a lot more than momentum, enterprise logos, and clever product names before paying infinity-money forever.
For now, Anthropic gets the bragging rights. The smarter question is how long they last once the market starts demanding receipts instead of vibes.
