Will Anthropic shares begin trading on a US stock exchange by December 31, 2026?

Anthropic filed confidentially for an IPO earlier this year and met prospective investors on October 14 to share third quarter numbers. Reuters reports a listing is planned for November, though no date has been confirmed.

How this question entered the record and how it will be resolved.

Resolution criteria

Resolves Yes if shares of Anthropic PBC (or a holding company created for its listing) begin regular trading on the Nasdaq or the New York Stock Exchange on or before December 31, 2026, as shown by the exchange or an effective registration statement on SEC EDGAR. Resolves No otherwise. Private secondary trading does not count.

Expected resolution

• CNBC, October 13, 2026: Anthropic filed confidentially and will disclose Q3 financials to investors; Reuters says it will list in November
• Bloomberg, October 1, 2026: listing targeted as soon as mid November
• Anthropic's prospectus has not yet been made public

Rising interest rates have rattled AI stocks, and other companies have delayed listings this autumn. OpenAI postponed its own IPO, and a large offering can slip by weeks for reasons outside the company's control.

• A public S-1 filing on EDGAR
• Market conditions for AI stocks
• Rate decisions in late October and December
