Anthropic Files for IPO at $965B Valuation After $65B Series H

Anthropic confidentially filed IPO paperwork this week, targeting an October 2026 listing, after closing a $65B Series H at a $965B post-money valuation — surpassing OpenAI's valuation for the first time. The company reported a Q2 revenue run rate of $47B, more than doubling quarter over quarter, driven largely by Claude Code adoption. For engineers: Anthropic's growth means continued heavy investment in coding tools, and an IPO creates pressure to maintain that trajectory. Claude Code is now the market-leading AI coding tool by usage among surveyed developers.
