How it resolves

The rules, word for word as Polymarket publishes them:

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.

How results are settled:
Polymarket markets are typically settled through UMA's optimistic oracle: a result is proposed after the event, can be disputed during a challenge window, and is final once undisputed or decided.

How to read these odds

A share of each outcome costs its chance in cents and pays $1 if it happens, so 93% means about 93¢ a share and roughly 1.08x back if right. On a ladder of dates or levels each rung is its own yes/no market, so the prices don't add up to 100%. Guides: reading Polymarket odds, odds to probability, glossary.

Are prediction market odds accurate?

On heavily traded markets, prices have tracked outcomes reasonably well: events priced near 70% happen roughly 70% of the time. They are a crowd estimate that moves with news, not a forecast, and long shots tend to be overpriced.
