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.**Rapid preparations for a record-setting debut are anchoring trader expectations around an October 2026 listing.** Anthropic confidentially filed its S-1 with the SEC on June 1 and is now preparing a public filing as early as late August, with Morgan Stanley, Goldman Sachs, and JPMorgan leading the effort. Explosive revenue growth—Q2 revenue reached $11.5 billion with an annualized run rate of $65 billion—supports ambitions for a $2 trillion valuation and a raise potentially exceeding SpaceX’s record, giving the company strong momentum ahead of rivals like OpenAI. A September window remains plausible if regulatory review accelerates, but the current timeline and market conditions continue to favor an October Nasdaq debut.
