Ten weeks. That’s how long it took Anthropic to more than double its valuation.
In February, Anthropic closed its $30 billion Series G at a $380 billion valuation — already one of the largest private funding rounds in history. Now, according to multiple sources, the company is raising roughly $50 billion at a valuation exceeding $900 billion, and it could close within two weeks.
If the numbers hold, Anthropic would surpass OpenAI’s $852 billion post-money valuation from its own record-breaking round earlier this year. The AI funding arms race just found a new gear.
The Numbers
According to TechCrunch’s reporting, Anthropic has asked investors to submit allocations within 48 hours. The round is expected to be roughly $50 billion, though given “soaring demand from investors,” the final valuation may exceed the $900 billion target.
CNBC confirmed the talks, reporting that Anthropic is weighing the raise at a valuation that would top OpenAI.
But here’s the detail that caught my eye: some early backers — particularly those who invested in 2024 or earlier — are skipping this round entirely. Instead, they’re waiting to cash out during Anthropic’s anticipated IPO later this year. When investors who know the company best are sitting out a round that’s almost certainly going to be heavily oversubscribed, that’s worth paying attention to.
The Revenue Story
The valuation isn’t coming from nowhere. Anthropic announced this month that its annual revenue run rate has surpassed $30 billion. Sources with knowledge of the company’s financials tell TechCrunch the actual run rate is closer to $40 billion.
That’s significant. In February, when Anthropic raised at $380B, the revenue story was still building. A $900B valuation at $40B run rate is roughly 22.5x revenue — aggressive, but not insane for a company growing this fast. For comparison, OpenAI’s $852B valuation against its revenue metrics tells a similar story of investors betting on the trajectory, not the current number.
This is also likely to be Anthropic’s last private round before going public. The company needs the capital for its massive computing needs — including a reported $50 billion data centre buildout starting in Texas and New York.
What’s Driving the Leap
A 2.4x valuation increase in 10 weeks isn’t normal, even by AI standards. What changed?
Enterprise momentum. Anthropic has been closing the enterprise gap with OpenAI. Claude’s enterprise features, managed agents platform, and partnerships with AWS and Google Cloud have given it a credible enterprise story. When we covered Anthropic closing the enterprise gap, the trajectory was already clear.
The Claude advantage. Claude’s reputation for safety and reliability has become a differentiator in enterprise procurement. Companies that were previously OpenAI-only are now running dual-vendor strategies, and Anthropic is winning the “safe second choice” position.
Compute hunger. AI companies need astronomical compute. Anthropic’s data centre strategy — including the Coatue/Next Frontier partnership — signals to investors that the company is thinking about infrastructure at the scale required. The money isn’t going to model training alone; it’s going to the physical infrastructure that makes model training possible.
IPO anticipation. The last private round before an IPO is often the most competitive. Investors who missed earlier rounds are fighting for position, driving the valuation up.
The Concentration Problem
Here’s what makes me uneasy. A $900 billion valuation puts Anthropic in the same territory as the world’s largest public companies — before it’s profitable, before it’s public, before it’s demonstrated sustainable margins.
The extreme concentration of capital in a handful of AI companies (Anthropic, OpenAI, and to a lesser extent Google DeepMind) creates systemic risk. If any of these companies stumble — a model safety incident, a regulatory crackdown, a competitive surprise — the cascade effects would be enormous. Venture capital is supposed to be diversified bets. Instead, we’re watching it concentrate into fewer and fewer hands at higher and higher multiples.
And there’s the NZ angle. When AI capital concentrates this heavily, small markets like New Zealand get further marginalised. The infrastructure investment, the talent acquisition, the policy influence — it all flows to where the money is, and the money is in San Francisco.
🔍 The Bottom Line
Anthropic raising $50 billion at $900B+ isn’t just a funding round — it’s a statement that the AI arms race has entered a new phase. The valuation leap from $380B to $900B in 10 weeks reflects genuine enterprise momentum and investor FOMO, but it also reflects a market that’s pricing in perfection.
The early investors sitting this out might be the smartest money in the room. They’ve seen Anthropic’s numbers up close, and they’re choosing to wait for the IPO rather than double down at a $900B valuation. That’s not a red flag — but it’s certainly a shade of amber.
One thing is clear: the AI company that was founded on safety-first principles is now one of the most valuable private companies on Earth. Whether those two things can coexist at $900 billion is a question worth watching.
