Resolution rules: read both before trusting a gap
Polymarket
This market will resolve to “Yes” if predict.fun officially launches a governance token by 11:59 PM ET on the date specified in the title. Otherwise, this market will resolve to “No”. The token must be actively and publicly transferable and tradable. Announcements alone do not qualify. The primary resolution source for this market will be information from predict.fun (https://predict.fun/), however a consensus of credible reporting will also be used.
Kalshi
If the WHO identifies any disease as a pandemic after issuance and by Dec 31, 2027, then the market resolves to Yes.
