Anthropic Files for IPO After $965 Billion Valuation Surpasses OpenAI
Anthropic, the company behind the Claude AI assistant, has confidentially filed a draft S-1 registration statement with the U.S. Securities and Exchange Commission, officially initiating the process for an initial public offering. The move comes just days after the company closed a staggering $65 billion Series H funding round that pushed its post-money valuation to $965 billion — surpassing rival OpenAI's $852 billion valuation from its March funding round.
The filing positions Anthropic as potentially the first AI company to reach the trillion-dollar mark in public markets. According to reports, the company's run-rate revenue has crossed $47 billion, driven by enterprise adoption of Claude, the launch of Claude Opus 4.8, and a landmark infrastructure deal with SpaceX for access to the Colossus supercomputer.
The IPO is expected to list in the fall of 2026, with Anthropic joining a wave of AI companies testing public market appetite. SpaceX is also preparing its own IPO, and OpenAI is expected to file soon. For developers and businesses, Anthropic's public listing means greater transparency, potential liquidity for early employees, and a more mature competitive landscape among frontier AI providers.
Anthropic's IPO filing marks a turning point for the AI industry — the race is no longer just about model benchmarks, it's about capital markets dominance. With OpenAI and SpaceX also preparing listings, we're entering an era where AI companies compete on Wall Street as fiercely as they do in the lab.
