**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 when done in response to a minor’s perception of sex or gender, while also barring state or federal funds, Medicaid reimbursements, and insurance coverage for such procedures.** It includes narrow exceptions for disorders of sex development or certain acquired conditions but excludes routine male circumcision. The measure qualified after supporters gathered well over the required signatures and was certified alongside a related sports eligibility initiative. Trader consensus around 61.5% for passage appears driven by the measure’s straightforward statutory language, alignment with restrictions already enacted in multiple other states, and public debate over irreversible interventions for those under 18, even as opposition campaigns highlight parental rights and existing medical access. The election outcome remains subject to turnout and concurrent ballot items.
