This market will resolve based on Anthropic's market capitalization at the closing price on its first day of trading. If no IPO occurs by June 30, 2026, 11:59 PM ET, the market will resolve to "No IPO by June 30, 2026". Market capitalization expresses the monetary value of a company’s outstanding shares, stated in its pricing currency. It is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If the relevant value falls exactly between two brackets, then this market will resolve to the higher range bracket. Resolution will be based on the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used. In the event of an interruption in the course of the normal trading session on Anthropic’s first day of trading (e.g., a circuit breaker or half-day), the market will resolve according to the official closing price of the abbreviated session. If no such official closing price is published, the market will resolve according to the next trading day on which an official closing price is published, treating that as the first day of trading for purposes of this market.**Traders assign a 99.6% probability to no Anthropic IPO closing by June 30, 2026, reflecting the early stage of the company’s process and standard regulatory timelines.** Anthropic confidentially filed its draft S-1 registration statement with the SEC on June 1, 2026, shortly after a $65 billion funding round that valued the artificial intelligence developer of the Claude large language models at $965 billion. The company explicitly stated that any public offering would depend on market conditions and completion of the SEC review, with no public filing or pricing details released. Analyst consensus and historical precedents for confidential filings point to a potential debut in the second half of 2026, most likely fall or Q4, after the typical multi-month comment-and-amendment cycle. With only about 12 days remaining until the resolution date, an IPO closing is mechanically implausible absent an unprecedented acceleration that has never occurred for a company of this scale. The slim odds attached to any specific closing market-cap bucket (each at 0.1–0.3%) further underscore that the market views a near-term listing as effectively off the table. A realistic challenge would require an extraordinarily rapid SEC turnaround combined with immediate market readiness—scenarios that remain highly improbable given the complexity of Anthropic’s revenue accounting, AI-safety disclosures, and overall size.
