In another update on a bill we previously covered, the fight for Kentucky sports betting just took another turn. What started as a wide-reaching proposal to restructure the entire market ended with a veto, an override, and a law that goes into effect this month.
What HB 904 Originally Set Out To Do
Reps. Michael Meredith and Matthew Koch introduced House Bill 904 back in March, and the early version was aggressive. It called for raising the sports betting age from 18 to 21, banning prop bets on Kentucky and Louisville college athletes, and adding fixed odds wagering to horse racing for the first time in state history. The most controversial piece targeted prediction markets. The original language would have barred any Kentucky-licensed sportsbook from operating a prediction market anywhere in the country after July 2027, a rule that directly threatened DraftKings, FanDuel, and Fanatics, since all three now run their own prediction products.
According to Legal Sports Report, those three operators account for close to 82 percent of the taxes Kentucky collects from sports wagering, so the stakes were massive. The bill still cleared the House by a lopsided 79-to-15 vote in March.
How The Bill Changed On Its Way To Becoming Law
Lobbying worked. The final version that passed the Senate narrowed the prediction market ban so that it applies only within Kentucky, allowing operators to keep running prediction platforms in other states without losing their Kentucky license. An amendment that would have required sportsbooks to accept wagers of up to $ 1,000 was also stripped out before the bill reached the governor's desk.
Everything else largely survived. The age hike to 21 is still in the final bill, along with the ban on prop bets tied to in-state college athletes and the new fixed odds horse racing framework. A companion bill, HB 757, adds a 14.25 percent tax on prediction market operators like Kalshi and Polymarket that don't hold Kentucky gambling licenses.
Gov. Andy Beshear vetoed HB 904, though not over the gambling provisions themselves. His objection centered on a clause that allows two state agencies to issue regulations without his review. Lawmakers responded fast, overriding the veto within two days by wide margins in both chambers. The law takes effect July 13.
For anyone using Kentucky betting apps, the practical changes show up almost immediately. Kentucky sports betting customers under 21 will be locked out once the new age requirement kicks in, and college prop markets involving in-state athletes will disappear from DraftKings, FanDuel, and every other licensed operator in the state.
The bigger question now is whether Kentucky's approach becomes a model. Rather than picking a legal fight with Kalshi and Polymarket directly, the state went after the licensees instead. As Gaming America noted, Rep. Meredith has acknowledged that federal law limits how far Kentucky can go in regulating prediction markets on its own, which is exactly why lawmakers built the bill around licensing conditions rather than an outright ban.
