Anthropic IPO

Anthropic officially filed to go public on June 1, 2026, submitting its IPO paperwork for one of the biggest IPOs in history. The IPO timeline has shifted, with the listing now delayed from the original October 2026 target to November 2026. As of late September 2026, the S-1 filing that was expected after Labor Day has not yet arrived, indicating continued preparation work. The company is seeking a dual-class voting structure that would give 50.1% voting control to seven co-founders (similar to Palantir's structure), as reported by The Information on September 24, 2026. The IPO is being closely watched as a test case for trillion-dollar listings, with market speculation around valuations ranging from $300 billion to $2 trillion. Nvidia is reportedly weighing a $10 billion stake in the IPO. Morgan Stanley and Goldman Sachs remain confirmed as lead underwriters, with Freshfields Bruckhaus Deringer serving as legal advisor. Ahead of the IPO, Anthropic has been aggressively ramping up dealmaking and shoring up investor confidence. The company was in talks to acquire Decart AI (reported August 13, 2026) as part of pre-IPO strategic moves and cleared a major regulatory hurdle in early July when the U.S. lifted export controls on Claude AI Fable and Mythos models. Anthropic strengthened its financial position with billions more in bank credit lines (mid-July 2026) and is expanding internationally with plans for Australian data centres. The company launched Claude Science on June 30th to expand revenue streams and released Claude Sonnet 5 at a steep discount. Trading interest remains exceptionally strong, with multiple platforms including Kraken, OKX, Coinbase, and STARTRADER offering pre-IPO trading products with leverage up to 5x. The IPO will reveal exact stakes for major investors Amazon and Google, who have invested billions in the company.
