Anthropic has closed a $65 billion Series H round at a $965 billion post-money valuation, co-led by Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Coatue, and others, with strategic participation from Samsung, SK Hynix, and Micron. The round includes $15 billion in previously committed hyperscaler investments, among them $5 billion from Amazon. Altimeter founder Brad Gerstner said Claude’s adoption among demanding enterprise customers positioned Anthropic to lead the next phase of AI innovation.
The raise arrives as Anthropic reported annualised run-rate revenue crossing $47 billion and projected a 130% revenue surge that would deliver its first operating profit. The company plans to deploy the capital toward safety research, expanded compute, and scaling Claude’s enterprise products.
On the same day, Anthropic released Claude Opus 4.8 — just 41 days after Opus 4.7 — responding to competitive pressure from OpenAI’s Codex and Google’s Gemini Flash. The new model emphasises honesty and self-correction, with early testers at Bridgewater Associates noting its tendency to proactively flag input and output issues that previous models left for users to catch. Alongside the model, Anthropic launched Dynamic Workflows in research preview, enabling Opus to coordinate complex tasks across hundreds of parallel subagents for large-scale code migrations.
Adding further complexity to the news cycle, Elon Musk publicly contradicted SpaceX’s own SEC filing over the terms of a $1.25 billion-per-month compute deal with Anthropic, with the filing describing a three-year agreement running to May 2029 while Musk characterised it as a short-term arrangement.
