1️⃣ Anthropic Raises $65B — Surpasses OpenAI at $965B Valuation
- What: Anthropic closed a $65B Series H round — expected to be its last private raise before an IPO — at a $965B post-money valuation.
- Why it matters: The round makes Anthropic the most valuable private AI company in the world, eclipsing rival OpenAI for the first time.
- Key number: $47B — Anthropic's annualised revenue run rate as of May 2026.
The round was co-led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, with further participation from Capital Group, Coatue, GIC, Blackstone, Fidelity, Temasek, and others. It folds in $15B of previously committed hyperscaler investments, including $5B from Amazon.
Anthropic says it will use the funds to advance safety and interpretability research, expand compute, and scale its product suite. The company projects a 130% revenue surge this year and expects its first operating profit, setting the stage for a public market debut. Both Anthropic and OpenAI are reported to be eyeing an IPO as soon as 2026 to fund the compute needed for the next generation of frontier models.
