Resolution rules: read both before trusting a gap
Polymarket
This market will resolve to "Yes" if Israel announces it has withdrawn all ground forces from Lebanon by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". For this market to resolve to "Yes" it is sufficient that Israel announces its ground forces have withdrawn from all Lebanese territory, regardless of if some Lebanese territory remains under their control or ground incursions by Israeli forces continue. However, an announcement of a planned or future withdrawal will not suffice. The Shebaa Farms area is considered Israeli territory for the purposes of this market and will not be considered toward its resolution. The primary resolution source for this market will be information from the Israeli government, however an overwhelming consensus of credible reporting confirming that Israel has withdrawn may also be used.
Kalshi
If the Federal Reserve announces an increase in the target range or target level for the federal funds rate after market Issuance and on or before Dec 31, 2026, then the market resolves to Yes.
