Voters in Colorado will decide Initiative 109 on November 3, 2026, which would require K-12 and collegiate athletic teams to be designated male, female, or co-ed based on biological reproductive systems, restricting participation accordingly. The measure qualified after Protect Kids Colorado gathered over 170,000 signatures, and a June 2026 U.S. Supreme Court ruling upheld similar state restrictions under Title IX and the Constitution. Opposition groups, including Families Not Politics, have raised substantially more campaign funds than supporters. Colorado’s existing protections for transgender athletes and the state’s Democratic-leaning electorate create competitive balance near even odds, while national momentum from the Supreme Court decision and parallel ballot efforts elsewhere could shift sentiment depending on polling trends, turnout patterns among key voting blocs, and final campaign spending through election day.
