When Anthropic becomes publicly traded

My median prediction for Anthropic becoming publicly traded is 16th November 2026, as the company’s internal October target will likely face minor slippage due to the administrative complexity of a trillion-dollar valuation and standard SEC review cycles following its June S-1 filing.

Resolves to the date on which shares of Anthropic (Anthropic PBC, or any successor or parent entity holding substantially all of Anthropic's business) begin trading on a major public stock exchange (NYSE, Nasdaq, or equivalent) following an initial public offering, direct listing, or merger with a publicly listed vehicle. The resolution date is the first day of public trading, not the date of any announcement or regulatory filing, as reported by credible sources (Reuters, Bloomberg, WSJ, FT).
