Colorado Initiative 110 is a ballot measure scheduled to appear in the statewide general election currently scheduled for November 3, 2026, which would prohibit healthcare professionals from providing surgeries to minors for the purpose of altering biological sex characteristics and prohibit state and federal funding from being used for these procedures. 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”. Subsequent litigation or any failure to implement the measure will have no impact on the resolution of this market. This market will resolve based on a consensus of credible reporting. If there is ambiguity, this market will resolve solely based on official information from the State of Colorado, including the Colorado Secretary of State (https://www.sos.state.co.us/). **Proposition 135**, a citizen-initiated statute on Colorado’s November 3, 2026 ballot, would prohibit healthcare professionals from performing surgeries on minors to alter biological sex characteristics and bar state, federal, Medicaid, or insurance funding for such procedures. It qualified in March 2026 after Protect Kids Colorado submitted nearly 165,000 signatures, exceeding the roughly 124,000–125,000 valid signatures required. The measure joins a companion initiative on school and college sports participation based on biological sex, with both backed by the same sponsors amid national debates over age limits for medical interventions. Similar restrictions have passed in 25 states, while Colorado previously enacted laws protecting access to gender-affirming care. Traders’ 66.5% implied probability for passage reflects the measure’s ballot qualification, signature momentum, and voter patterns on comparable policies elsewhere, though final outcomes depend on turnout and campaign spending in the remaining weeks.
