This market will resolve to “Yes” if this ballot measure is approved as a result of the Colorado statewide general election currently scheduled for November 3, 2026. Otherwise, this market will resolve to “No.” If voting on the specified ballot measure does not occur, or the results thereof are not known definitively, by March 31, 2027, this market will resolve to “No”.
