Colorado’s sports betting reform bill has cleared the House, but prediction market operator Kalshi sits outside the same state playbook, and that is where things get messy.
House Vote Puts SB26-131 Near the Finish Line
Colorado’s SB26-131, the Sports Betting Protections bill, passed the House on May 9 by a 50-13 vote after previously clearing the Senate 20-14. The official bill tracker still lists the measure as “Under Consideration,” meaning the final paperwork is not quite done, but the proposal is now much closer to Gov. Jared Polis’ desk than it was when the week began.
The bill is aimed at tightening the rules around online sportsbooks in Colorado, where legal sports betting launched in May 2020 after voters approved it in 2019. For players, the biggest changes are practical ones: fewer ways to reload quickly, fewer nudges from operators, and more limits on how sportsbooks can chase younger audiences.
The New Rules Would Hit Deposits and Promos
Under the current version, licensed online sportsbooks would be barred from accepting more than six deposits from one person during a gaming day. They also could not send push notifications or texts that solicit bets or deposits, which means fewer “just one more wager” pings during a bad Sunday slate.
Credit cards would also be off the table for sports betting deposits. Operators that break the credit card rule could face penalties, with the bill allowing a fine of up to $25,000 for that violation.
Advertising rules were softened as the bill moved through the Capitol, but sportsbooks and marketing affiliates would still be blocked from targeting people under 21 or advertising on media where the majority audience is expected to be under 21. Operators would also have to submit annual data to the state starting in 2028, with public reports due every three years beginning in 2029.
Prop Bet Ban Gets Cut from the Final Push
Earlier language would have gone much further, including a ban on player prop bets and tougher ad limits. Those pieces were stripped out before the House vote, leaving a narrower bill focused on deposits, credit cards, youth-facing ads, operator reporting, and bet-soliciting notifications.
That matters for regular bettors. Player props are not going away under this version, so the same Nikola Jokić points market or Broncos receiver yardage bet should remain available at licensed books. The real change is around how often players can reload and how aggressively apps can pull them back in.
Kalshi Complicates the Picture
Then there is Kalshi, the prediction market platform that CPR reported is operating in Colorado outside the state sportsbook system. According to the report, Kalshi is not licensed by Colorado as a sportsbook, does not pay the same sports betting taxes that help fund water projects, and is not covered by state problem-gambling rules in the same way licensed books are.
Kalshi’s pitch is that it is not a sportsbook at all. It describes itself as an exchange where users buy yes-or-no event contracts, including sports-related markets. Kalshi says it is licensed and regulated by the Commodity Futures Trading Commission because it offers event contracts, while state officials and gaming regulators in several places argue that sports contracts can look a lot like betting with a different hat on.
For Colorado players, that creates a strange split screen. A licensed sportsbook may soon face stricter deposit, credit card, ad, and notification rules, while a prediction market offering sports contracts may not be touched by the same state bill. Same game, different wrapper, and potentially a very different set of protections.
Players May Feel the Gap First
SB26-131 is being sold as a consumer-protection measure, not an attempt to kill Colorado sports betting. That distinction matters. The bill leaves the legal market intact, but tries to slow the speed at which players can chase losses and limit marketing aimed at younger users.
The catch is that gambling habits do not care much about regulatory categories. A player who is blocked from using a credit card at a sportsbook may still find sports-style contracts elsewhere. That is why Kalshi has become such a headache for states: it forces lawmakers to answer whether a sports outcome market is meaningfully different from a sportsbook bet just because the product is structured as a trade.
Colorado’s bill may soon reshape the sportsbook experience for everyday bettors. The Kalshi fight suggests the next round will be bigger, messier, and aimed at the line between gambling, trading, and whatever clever name comes next.
