This market will resolve to "Yes" if Anthropic shares are listed on a public securities exchange and open for trading by 11:59 PM ET on the listed date. Otherwise, this market will resolve to "No." If Anthropic is acquired by another company that is already public, this market will immediately resolve to "No." The primary resolution source for this market is official filings and announcements from Anthropic and the relevant securities exchange on which the shares are listed, including SEC filings (e.g., Form S-1, Form 8-A), exchange listing confirmations, and official press releases from Anthropic; however a consensus of credible reporting may also be used.Anthropic’s confidential SEC S-1 filing on June 1, 2026, following its record $65 billion Series H round at a $965 billion post-money valuation in late May, serves as the dominant catalyst shaping trader views on an IPO timeline. Run-rate revenue exceeding $47 billion and sustained enterprise adoption of Claude underpin the near-trillion-dollar valuation, while the filing explicitly preserves flexibility tied to market conditions rather than committing to a date. With SEC review underway and reports pointing to a potential September or early-fall window, alongside OpenAI’s parallel filing, sentiment reflects high implied probability of a 2026 debut if equity markets remain receptive to large AI offerings. Key swing factors include Treasury yield stability, overall IPO volume, and any regulatory feedback on the registration statement.
