Resolution criteria

If Naomi Osaka wins the 2026 US Open Women's Singles professional tennis tournament, then the market resolves to Yes.

ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.
