The closely contested 51% implied probability for passage of Colorado's Initiative 109 reflects active campaigning on both sides ahead of the November 3, 2026, vote. Protect Kids Colorado qualified the measure by gathering over 168,000 signatures, defining school and college athletic teams by biological sex based on reproductive systems and restricting participation accordingly. Opposition groups such as Hands Off Colorado and Rocky Mountain Equality are mobilizing voters in the blue-leaning state, framing the initiative as exclusionary while supporters emphasize fairness in women's and girls' sports. Similar measures appear on ballots in Arizona and Washington, and a companion Colorado initiative targets medical procedures for minors. Upcoming fall campaign spending, turnout efforts, and any late polling shifts on this issue could alter the balance before election day.
