Shaw Ventures, DST Global and Fidelity. Strategic infrastructure partners Samsung, SK Hynix and Micron also participated. The company said $15 billion of the round comprised previously committed hyperscaler investments — including $5 billion from Amazon. Anthropic released Claude Opus 4.8 on the same day and said it will use funds to expand safety research, compute for Claude, and scale products and partnerships. The startup reported a run-rate revenue above $47 billion and expects profitability following a projected revenue surge.
Anthropic Now World's Most Valuable AI Startup

The round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia and sits on top of earlier hyperscaler commitments of roughly $15 billion (about $5 billion from Amazon).
