Resolution rules: read both before trusting a gap
Polymarket
This market will resolve to “Yes” if Vladimir Putin ceases to be President of Russia for any period of time between market creation and the specified date (ET). Otherwise, this market will resolve to “No”. An announcement of Vladimir Putin's resignation/removal before this market's end date will immediately resolve this market to "Yes", regardless of when the announced resignation/removal goes into effect. If the specified individual is detained, effectively removed from the specified position, or otherwise permanently prevented from fulfilling the duties of the specified position within this market’s timeframe, it will qualify for a “Yes” resolution. The resolution source for this market will be official information from Vladimir Putin and the government of Russia; however, a consensus of credible reporting may also be used.
Kalshi
If the Federal Open Market Committee announces a reduction in the target range for the federal funds rate at least once after market Issuance and on or before June 30, 2027, then the market resolves to Yes.
