Polymarket — resolution criteria

This market will resolve to "Yes" if the Treasury 30-year yield reaches or is higher than the listed value for any date between September 3, 2026 and September 30, 2026. Otherwise this market will resolve to "No". This market will resolve as soon as the Treasury 30-year yield reaches or is higher than the listed value, or once data is available for September 30, 2026. If no qualifying value is published and data is not available for September 30, 2026 by October 14, 11:59 PM ET, this market will resolve to "No".
