Resolution rules: read both before trusting a gap

Polymarket

This market will resolve to “Yes” if Benjamin Netanyahu ceases to be Prime Minister of Israel for any period of time between market creation and the specified date (ET). Otherwise, this market will resolve to “No”. An announcement of Benjamin Netanyahu'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. The resolution source for this market will be official information from Benjamin Netanyahu and the government of Israel; however, a consensus of credible reporting may also be used.
