Colorado’s November 3, 2026 ballot includes three citizen-initiated statutes from the parent coalition Protect Kids Colorado. They were formerly Initiatives #108, #109, and #110. Each passes with a simple majority and would take effect on January 1, 2027. Ballots are going out by mail to voters across Colorado October 2–9, 2026.

This is a plain summary of what each measure says, drawn from the measure text and the Legislative Council’s 2026 Ballot Information Booklet.

Proposition 133: Penalties for Human Trafficking of a Minor

Short title: the “Children Are Not For Sale Act.”

Current law: human trafficking of a minor for sexual servitude is a class 2 felony, with 8 to 48 years in prison and 5 years of mandatory parole.
Under Proposition 133: it becomes a class 1 felony with a mandatory sentence of life in prison without parole. Judges would no longer have sentencing discretion.
It adds a new form of the crime: knowingly trading anything of monetary value to buy or sell sexual activity with a minor. That covers buyers as well as sellers.
The governor’s power to pardon, commute, or grant clemency is unchanged.

Proposition 134: Male and Female Participation in School and Collegiate Sports

Short title: the “Protect Women and Girls Sports Act.”

Every school-based team or sport must be designated male, female, or coeducational. That covers public, charter, private, and religious schools from elementary school through college, including intramural and school-sponsored after-school sports.
Students compete on the team that matches their sex, or on a coed team. A female may join a male team when no female team is offered.
Sex is defined by biology: male means a reproductive system organized around producing sperm, and female means one organized around producing ova (eggs).
No government entity, accreditor, or athletic association may take a complaint, open an investigation, or take adverse action against a school for keeping a separate team for females.
Each school’s governing body must adopt an implementing policy. For public K-12 districts, the Commissioner of Education enforces it.
People born with a disorder or difference of sex development keep all protections and accommodations under federal law.

Background. The Colorado High School Activities Association’s rules have allowed students to play on teams matching their gender identity. At least seven Colorado schools and districts have adopted policies keeping males out of female sports. NCAA rules limit women’s competition to females. In June 2026, the U.S. Supreme Court ruled that states may keep separate male and female sports based on sex.

Campaign ad. On October 7, 2026, Protect Kids Colorado announced a 30-second ad for Proposition 134. In it, Colorado female athletes describe competing against males in volleyball, soccer, and wrestling. It is shown here as a reference for readers following the measure. We Speak Truth does not endorse or oppose ballot measures.

Proposition 135: Prohibit Surgery on Minors in Response to Perception of Sex or Gender

Short title: the “Protect Children From Irreversible Sex Change Surgery Act.”

No health-care professional or other person may knowingly perform, prescribe, administer, or provide any surgery to a minor (under 18) for the purpose of altering biological sex characteristics in response to the minor’s perception of sex or gender.
No state or federal funds, Medicaid reimbursement, or insurance coverage may pay for those surgeries.
Exceptions: male circumcision, and treatment for medically verifiable disorders of sex development or acquired physical or chemical abnormalities.
It does not cover non-surgical interventions such as puberty blockers and cross-sex hormones.
Proponents submitted 164,922 signatures, and the Secretary of State certified the measure for the ballot on March 17, 2026.

According to KFF, as cited by the New York Post, 27 states have laws banning or limiting sex-rejecting surgeries for minors. In February 2026, the American Society of Plastic Surgeons recommended that surgeons delay gender-related breast/chest, genital, and facial surgery until a patient is at least 19.
