Colorado Sports Betting Prop Ban Advances Through Senate Committee

Colorado sports betting prop ban legislation is making headlines as Senate Bill 26-131 clears its first major hurdle in the state legislature. The bill, which targets proposition wagers, sportsbook advertising, and daily deposit activity, represents the most aggressive regulatory move Colorado has taken since legalizing online sports betting in 2020. If enacted, SB 26-131 would reshape how operators do business in one of America’s fastest-growing wagering markets.

The measure sailed through the Senate finance committee in late March 2026, drawing support from both sides of the aisle. Sponsors argue that six years of largely unchecked operator activity have produced measurable harm, particularly among younger bettors who came of age alongside mobile sportsbook apps. Colorado reported more than $8.2 billion in total handle during 2025, yet problem gambling referrals in the state jumped 34 percent over the same period.

What the Colorado Sports Betting Prop Ban Would Actually Prohibit

At its core, SB 26-131 takes aim at three pillars of the current sportsbook model. First, the bill would eliminate most proposition bets, the player-specific wagers that have become a cash cow for operators like DraftKings, FanDuel, and BetMGM. Prop bets on individual athlete performance accounted for roughly 29 percent of Colorado’s online handle in Q4 2025, according to the Colorado Division of Gaming.

Second, the legislation introduces sweeping advertising restrictions. Sportsbook ads would be banned between 8 a.m. and 10 p.m. local time and during any live sporting event broadcast. Bonus-style promotional offers, the “bet $5, get $200” campaigns that flood social media feeds, would be prohibited entirely. Operators would also lose the ability to send push notifications or text messages soliciting wagers.

Third, the bill proposes daily deposit caps and bans credit card funding for sportsbook accounts. Bettors would be limited to five deposits per day, and no deposit could be funded through a credit card, overdraft facility, or buy-now-pay-later product. That provision mirrors Sweden’s April 2026 credit gambling ban, which Colorado legislators explicitly cited during committee testimony.

Industry Pushback and Operator Concerns

Sportsbook operators are not taking the colorado sports betting prop ban quietly. The American Gaming Association issued a statement calling SB 26-131 “well-intentioned but dangerously overbroad,” warning that eliminating prop bets would push bettors toward unregulated offshore platforms. DraftKings’ head of government affairs told reporters the ad restrictions alone could cut the company’s Colorado customer acquisition by 40 percent.

Smaller operators fear the deposit caps could make Colorado uneconomical. “You are basically telling casual bettors they can stay, but making it impossible for operators to reach them,” said one regional sportsbook executive who asked not to be named. Industry lobbyists have proposed an alternative framework: tighter age verification, mandatory responsible gambling messaging every 30 minutes of in-app activity, and voluntary ad curfews during youth-oriented programming.

How Colorado Compares to Other States Tightening Rules

Colorado is not alone. Massachusetts passed advertising limits during live broadcasts earlier in 2026, and Connecticut is weighing deposit frequency restrictions of its own. But no state has bundled prop bet elimination, ad curfews, credit bans, and deposit caps into a single piece of legislation the way SB 26-131 does. Analysts at Eilers & Krejcik Gaming called the bill “the most comprehensive state-level sports betting reform package introduced anywhere in the US since PASPA repeal.”

The colorado sports betting prop ban also arrives as regulators in Asia and Europe are moving in similar directions. Malaysia’s evolving regulatory framework is worth watching for bettors tracking global trends.

What Happens Next for SB 26-131

The bill now heads to the full Colorado Senate, where a floor vote is expected before the end of April. Governor Jared Polis has not publicly endorsed or opposed SB 26-131, though his office issued a statement in March noting the administration “supports evidence-based player protections.” If the Senate passes the measure, the House State Affairs committee would take it up in May.

For operators, the next few weeks are critical. Industry groups are reportedly pooling resources for a coordinated lobbying campaign, and at least two major sportsbooks have retained outside counsel to challenge specific provisions on First Amendment grounds should the colorado sports betting prop ban become law. Whether the bill survives in its current form or gets watered down in negotiations, one thing is clear: Colorado’s regulatory honeymoon period for online sports betting is over.

The colorado sports betting prop ban debate will likely influence similar legislative efforts in at least half a dozen other states before the end of the 2026 session cycle. States watching include New Jersey, Michigan, and Pennsylvania, all of which saw record handle numbers in 2025 and face their own growing calls for tighter consumer safeguards.
