Colorado sports bettors will soon see tighter rules on how they deposit money, how sportsbooks contact them, and how betting companies advertise. Senate Bill 26-131 has become law and is expected to take effect August 12, 2026, unless a referendum petition delays it.
For players, this is not a ban on sports betting. It is a set of new limits aimed at slowing down risky betting habits and cutting back on aggressive sportsbook marketing.
Six Deposits Per Gaming Day
The biggest everyday change is the deposit limit. Online sportsbooks will not be allowed to accept more than six separate deposits from one person during a “gaming day,” which the law defines as a 24-hour period set by the sportsbook for tax and reporting purposes.
So, players can still bet, but they cannot keep reloading their accounts over and over all day. Someone who usually makes one or two deposits probably will not notice much. A player who keeps topping up after losses will hit the limit faster.
Credit Cards Are Out
Colorado will also ban sportsbooks from accepting deposits funded by credit cards, including indirect credit-card funding.
That means players will need to use other approved payment methods instead. The idea is simple: lawmakers do not want people betting with borrowed money. The state’s fiscal note also points out that DraftKings stopped credit-card use in August 2025 and FanDuel followed in March 2026, meaning many Colorado bettors may already be seeing this change in practice.
Fewer “Come Back and Bet” Alerts
The law blocks online sportsbooks from sending push notifications or mobile alerts that ask Colorado account holders to place bets or make deposits.
For players, this could make betting apps feel less intrusive. You may still open the app and browse odds yourself, but operators will have less freedom to ping your phone with reminders to bet.
Sportsbooks Cannot Target Under-21 Audiences
Colorado’s new rules also stop sportsbooks and marketing affiliates from targeting people under 21 or creating ads clearly meant for younger audiences. They also cannot advertise on media where most of the expected audience is under 21.
This is one of the more player-protection-focused parts of the law. It is aimed less at current bettors and more at keeping sports betting from being pushed toward younger fans.
Prop Bets Survive, For Now
One thing players should know: the final law does not ban proposition bets. Earlier versions reportedly included a prop-bet ban, but that part was removed before final passage. Prop bets are wagers on specific events inside a game, like a player’s passing yards or which team scores first.
So, for now, Colorado bettors should still expect player props and game props to remain available through licensed sportsbooks.
Why Colorado Is Doing This
Colorado’s betting market has grown fast. The state Division of Gaming reported more than $6.3 billion in wagers for the fiscal year, along with a record $36.8 million in sports betting tax revenue. More than $33 million was approved for Colorado water conservation efforts from sports betting tax revenue.
Supporters say the new law adds needed guardrails to a market that has become part of daily sports culture. Opponents, including major operators, have warned that tighter rules could push some players toward unregulated offshore sportsbooks.
Bottom Line for Players
Colorado players can still bet legally through licensed sportsbooks. The difference is that the experience will be a little less frictionless: fewer deposits, no credit-card funding, fewer betting prompts, and stricter rules around youth-facing ads.
For casual bettors, the changes may be minor. For players who chase losses, reload often, or rely on credit cards, the new rules will be much more noticeable.
