How it actually resolves
The written rules below decide this market — not the headline.
Rules risk: Resolves on "credible reporting", which leaves room to argue; the end date has passed and it is still open; a result has been proposed and is in the challenge window.
Full rules from Polymarket
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.
