This market will resolve based on the calendar month (ET) in which Anthropic's initial public offering (IPO) occurs. The resolving month will be the calendar month (ET) containing the first day on which Anthropic shares are listed and open for regular-way trading on a public securities exchange. An IPO refers to Anthropic shares becoming listed and open for trading on a public securities exchange, whether through a traditional initial public offering or a direct listing. If Anthropic goes public through a merger, acquisition, or absorption by an entity that is already publicly traded, including a special purpose acquisition company, this market will resolve to "No IPO before 2028". If no IPO occurs by December 31, 2027, 11:59 PM ET, the market will resolve to "No IPO before 2028". Announcements, filings, or scheduling of an IPO will not suffice; this market will resolve after public trading has begun. Resolution will be based on information from the primary exchange.Anthropic's confidential S-1 filing with the SEC on June 1, 2026, after a $65 billion Series H round that valued the large language model developer at $965 billion, has anchored trader expectations for an October 2026 listing. Recent reports confirm active investor meetings and preparations with lead banks targeting a September or early October window, consistent with standard post-filing review and roadshow timelines for major AI companies. Competitive pressure from OpenAI's parallel filing and the broader rush of AI firms to public markets adds momentum, while factors like SEC comment resolution, market conditions, and lockup structuring introduce limited scope for slippage into November or later. This setup explains the market's pronounced tilt toward October as the consensus outcome backed by real capital.
