Colorado's State Senate passed a major online sportsbook consumer protection bill in May 2026 that would impose some of the strictest restrictions in the US on sports betting operators if signed into law. The bill includes mandatory deposit limits, restrictions on advertising during sporting events, and new requirements around problem gambling resources. Industry trade groups have called the measure a "national model" if approved by the Governor, while operators including DraftKings and FanDuel are lobbying for amendments that would soften the impact.
Quick answer: Colorado's State Senate passed Senate Bill 26-145 in May 2026, imposing mandatory deposit limits, advertising restrictions during sporting events, and stronger problem gambling protections on online sportsbooks. The bill awaits Governor Jared Polis's signature and could become the most restrictive US sports betting law if enacted. Industry operators are lobbying for amendments.
What the Bill Requires
Senate Bill 26-145 contains five major provisions that would reshape Colorado's online sports betting market:
First, mandatory deposit limits for all online sportsbook accounts. New accounts would be required to set a weekly deposit limit during onboarding, with the maximum default limit set at $2,500 per week. Players can voluntarily lower the limit but raising it above the default would require a 24-hour cool-down period and acknowledgment of problem gambling resources.
Second, advertising restrictions during live sporting events. The bill prohibits sports betting advertisements during the actual broadcast of any sporting event in which betting markets are offered. This includes television, streaming, and in-venue advertising. The provision is modeled on similar restrictions in the United Kingdom and Italy.
Third, mandatory problem gambling resource disclosure. Every sports betting advertisement, in-app screen, and marketing communication must include the National Problem Gambling Helpline number and a clear link to responsible gambling resources. Currently, Colorado law requires similar disclosure but with less prominence and specificity.
Fourth, restrictions on parlay marketing. The bill prohibits sportsbooks from marketing parlays as the "best" or "smartest" bet type, citing research showing that parlays have significantly higher house edges than straight bets. Sportsbooks could continue to offer parlays but could not market them as superior value.
Fifth, enhanced age verification. The bill increases the legal age verification requirements, requiring third-party identity verification at account creation and enhanced re-verification for users who change deposit limits, withdraw large amounts, or engage in unusual play patterns.
Why Colorado Acted Now
Colorado legalized online sports betting in May 2020, becoming an early-mover state. Six years later, the market has matured: monthly handle regularly exceeds $500 million, and Colorado is one of the top 10 states by per-capita sports betting volume. The maturation has also surfaced consumer protection concerns that legislators say justify a stronger regulatory framework.
Specific concerns include rising problem gambling rates, particularly among young men ages 21-34. Colorado-based research has shown that this demographic group has problem gambling rates approximately 2.4 times the statewide average. Mandatory deposit limits and advertising restrictions target this group specifically.
The state legislature also cited high-profile athlete and coach gambling scandals from 2024 and 2025 — including the NBA's Jontay Porter case and several college football match-fixing investigations — as evidence that current consumer protection frameworks are insufficient.
Industry Response and Lobbying
Major sportsbook operators have organized aggressive lobbying against the bill. DraftKings, FanDuel, and BetMGM have collectively spent more than $2.4 million on Colorado lobbying in the past six months according to state campaign finance disclosures. The American Gaming Association (AGA) has filed formal opposition citing concerns about the advertising restrictions and parlay marketing limits.
Operator arguments focus on three points. First, that the advertising restrictions could violate First Amendment commercial speech protections, potentially exposing the state to litigation. Second, that mandatory deposit limits push players toward unregulated offshore sportsbooks where no protections exist. Third, that the parlay marketing restrictions are overly prescriptive and not based on objective standards.
Comparison with Other State Laws
If signed, SB 26-145 would make Colorado the most restrictive US sports betting state. Currently, only Massachusetts has comparable advertising restrictions, and no state requires the level of mandatory deposit limits proposed in the Colorado bill.
The closest international parallels are the UK Gambling Act 2025 amendments and the Italian gambling advertising ban. Both jurisdictions have implemented similar advertising and deposit limit frameworks and offer real-world data on consequences. UK problem gambling rates have declined modestly since the 2025 amendments, though direct attribution is contested. Italian betting handle declined sharply after the advertising ban but has since stabilized.
Potential Governor's Office Outcomes
Governor Polis has not publicly committed to signing or vetoing the bill. Three outcomes are possible:
The Governor signs the bill as passed. This would make the restrictions law and likely trigger immediate operator litigation over the advertising provisions. Implementation would begin January 1, 2027.
The Governor returns the bill to the legislature with proposed amendments. This is the most likely outcome based on Polis's track record of seeking middle-ground solutions on contentious bills. Likely amendments would soften the advertising restrictions while preserving the deposit limit and problem gambling disclosure provisions.
The Governor vetoes the bill. This is the least likely outcome but possible if the operator lobbying is effective. The bill passed with sufficient support that the legislature might attempt to override a veto.
The National Implications
If Colorado enacts SB 26-145, several other states are expected to consider similar legislation. Massachusetts, New York, and Illinois have all signaled interest in stronger consumer protection frameworks. The National Council of Legislators from Gaming States has scheduled a 2026 summit specifically focused on consumer protection legislation, with Colorado's bill expected to be a key reference point.
For sportsbook operators, the national patchwork of varying restrictions creates significant operational complexity. Compliance costs for advertising restrictions alone would rise substantially if multiple states adopt similar frameworks.
What Sports Bettors Should Watch
Colorado residents should watch for the Governor's decision over the next 30 days. If the bill becomes law, current online sportsbook accounts would need to be updated to comply with the new requirements before January 1, 2027.
Bettors in other states should monitor whether their state legislature considers similar legislation. The Colorado outcome could create momentum for adoption elsewhere, particularly in states with mature sports betting markets and active problem gambling research communities.
