Will Anthropic or OpenAI IPO first?

Traders currently price "Anthropic" at 85% for "Will Anthropic or OpenAI IPO first?". The market has traded $279K in total volume and resolves Dec 31, 2027. Anthropic’s earlier confidential S-1 filing on June 1, 2026, and reports of a potential Nasdaq listing as soon as October or fall 2026 underpin the strong trader consensus favoring it to reach public markets first. OpenAI filed its own confidential registration several days later and has since signaled a possible delay until 2027 amid internal deliberations over timing and market conditions. Both artificial intelligence companies continue scaling large language model offerings amid intense competition for capital and talent, but Anthropic’s procedural lead and firmer near-term window give it a clear edge in the current filing race. Upcoming catalysts include any public updates on underwriter selections, valuation targets near $1 trillion, or shifts in broader market sentiment following recent high-profile tech listings.
