Anthropic Raises $65B at $965B Valuation — Surpasses OpenAI

Anthropic closes a $65B Series H at $965B post-money, leapfrogging OpenAI's $852B. Run-rate revenue hits $47B. The round includes $15B from hyperscalers (Amazon $5B) and strategic infrastructure partners (Micron, Samsung, SK Hynix). IPO prep underway.


The Number That Changes Everything

$965 billion. That's not a typo. On May 28, Anthropic announced a $65 billion Series H that values the company at $965 billion post-money — surpassing OpenAI's last known valuation of $852 billion (March 2026) and making Anthropic the world's most valuable private AI company.

For context: Anthropic was valued at $183 billion in February (Series F). That's a 5.3x step-up in three months. The $65 billion raise is the largest private financing round in tech history, eclipsing even the most aggressive sovereign wealth fund deployments.

Where the Money Comes From

The cap table tells the real story. The round was led by Altimeter, Dragoneer, Greenoaks, and Sequoia, with Coatue and ICONIQ as co-leads. But the strategic signal is in the infrastructure partners: Micron, Samsung, and SK Hynix — the memory and storage supply chain — bought in. So did Amazon with $5 billion (part of a previously committed $15 billion from hyperscalers), on top of their earlier $8 billion.

This isn't financial engineering. It's compute procurement disguised as equity. Anthropic has committed to spending over $100 billion on Amazon's cloud over the next 10 years. The equity round funds the down payment; the infrastructure partners ensure supply.

The Revenue Reality

Anthropic disclosed run-rate revenue of $47 billion — up from effectively zero two years ago. That's a revenue multiple of ~20x, which is aggressive but not insane for a company growing 3x year-over-year in the hottest category in tech.

The revenue driver: Claude Code. Enterprise adoption of Anthropic's coding agent has been the single fastest product ramp in the company's history. While OpenAI pivoted to enterprise after ChatGPT consumer saturation, Anthropic built for developers first, enterprises second — and the order matters.

IPO Watch

Reuters reports Anthropic is "preparing for a public listing, possibly as quickly as this year." The $65 billion round structured with significant previously-committed hyperscaler capital ($15B) looks like a pre-IPO bridge: clean up the cap table, secure 10-year compute contracts, show $47B+ run-rate, go public.

If they IPO in 2026, it would be the largest tech listing since... arguably ever.

Strategic Signal

Three things this tells us about where the market is going:

  1. Model labs are becoming infrastructure companies. The $100B Amazon commit + Micron/Samsung/SK Hynix equity = Anthropic is vertically integrating compute supply chain, not just training models.
  2. Coding agents are the killer app. Claude Code revenue trajectory forced OpenAI's enterprise pivot (Codex) and now Microsoft/Google's competitive response. The $30B AI coding market (26% CAGR) is the beachhead.
  3. The duopoly is now a triopoly. Microsoft/OpenAI, Google, Anthropic. Three full stacks. Everyone else is a feature, not a platform.

What to Watch

  • S-1 filing timeline — "this year" means H2 2026
  • Whether $47B run-rate sustains or shows seasonal enterprise budget flush
  • If OpenAI responds with its own mega-round (rumored $100B+)
  • Amazon's total Anthropic exposure: $8B + $5B + $100B cloud commit = $113B+

The Bottom Line

Anthropic just fired the starting gun on the public-markets phase of the AI arms race. $965B valuation, $47B revenue, $100B compute commit, IPO imminent. The private-market era is ending. The fire just went public. 🔥
