Anthropic’s next round could value it at $900B+ and it’s moving fast

Anthropic is moving fast on its next fundraise. Sources familiar with the matter tell me the company has given investors a 48-hour window to submit allocation requests for what could be a $900B+ valuation round. That’s not a typo—nine hundred billion, with a B.

For context, that would put Anthropic in the same valuation stratosphere as companies like SpaceX and ByteDance, and well above most publicly traded tech giants. The speed of this ask is unusual even by AI startup standards. Most mega-rounds take weeks of back-and-forth, not two days.

What’s driving this? Two things, I think. First, demand for frontier AI models is still insatiable. Anthropic’s Claude has carved out a real niche in enterprise and safety-conscious markets, and the company has been shipping products at a pace that makes OpenAI look almost leisurely. Second, the timing feels strategic—maybe they want to close before some market shift or competitor announcement.

The $900B+ figure is higher than I expected. Anthropic was valued around $60B just over a year ago. A jump like that doesn’t happen unless investors are betting on something transformative—either revenue growth that justifies the multiple, or a belief that whoever wins the AI race will capture trillions in value. I’m skeptical of the latter, but the market clearly disagrees.

There’s also the question of who’s writing these checks. Anthropic has deep ties with Amazon and Google, but at these numbers, you’d expect sovereign wealth funds, pension funds, and maybe some Middle Eastern capital to come in. The 48-hour deadline suggests they already have anchor investors lined up and are just filling out the allocation.

One thing I’d watch: the terms. At this valuation, later-stage investors usually demand protections—liquidation preferences, anti-dilution clauses, board seats. If Anthropic is giving those up, it signals confidence in their trajectory. If they’re not, the round might be more about optics than substance.

Either way, this is a signal that the AI funding frenzy isn’t cooling off. If anything, it’s accelerating. I’ll be curious to see who blinks first—the investors who submit in 48 hours, or the skeptics who think this is peak froth.
