Forward watch
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.
No otherwise — if the Yes condition is not satisfied by the resolution criteria.
This market resolves according to the source market rules. Review the source market before relying on this interpretation.
