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.Recent Reuters reporting that Anthropic has delayed its IPO prospectus to late September while targeting mid-October marketing and a possible listing days before the November U.S. midterms has reinforced trader consensus around October 2026 at 62.5% implied probability. The Claude developer’s rapid revenue growth, pursuit of a $15 billion credit facility, and expectations of a roughly $2 trillion valuation continue to support the tight window, though plans remain subject to regulatory review and market conditions. November holds 35% odds as a fallback if timelines slip, while later months reflect lower trader expectations for any major delays.
