Quick Answer: Kentucky’s HB 904 raises the sports betting age from 18 to 21, restricts collegiate prop betting, and introduced prediction market provisions that DraftKings, FanDuel, and Fanatics warned could push them out of the state — putting more than $40 million in annual tax revenue currently directed toward teacher pensions at stake. The measure has since become law, taking effect on July 15, 2026.

Kentucky has enacted HB 904 after a legislative fight in which the operators responsible for nearly 82% of the state’s sports betting tax revenue — DraftKings, FanDuel, and Fanatics, according to Legal Sports Report — warned that the bill’s prediction market provisions could gut the regulated market and force them to exit entirely. More than $40 million in annual tax revenue, money currently directed toward teacher pensions, hung in the balance as the bill moved through Frankfort.

What HB 904 Actually Does

Age Limits and Collegiate Prop Bets

HB 904 raises the minimum age for sports betting in Kentucky from 18 to 21. Coverage of the bill’s advance noted it would raise the betting age to 21, restrict how people can wager, and tighten oversight across multiple forms of gaming.

The legislation also tightens collegiate betting. Spectrum News reported on March 13, 2026 that the bill bans proposition bets on Kentucky college athletes. Collegiate player prop bets have drawn scrutiny across multiple states due to concerns about athlete welfare and the potential for manipulation, per Legal Sports Report.

Beyond age restrictions, the bill mandates that sportsbooks must generally accept wagers up to $1,000 unless specific exceptions apply. That provision limits how aggressively operators can restrict sharp or winning bettors, a point of ongoing tension between regulators and the industry.

Prediction Market Provisions That Alarmed Operators

The most consequential section of HB 904 deals with prediction markets. According to reporting by Legal Sports Report, the bill’s prediction market rules may be incompatible with how major operators currently structure their offerings. DraftKings, FanDuel, and Fanatics — which collectively account for nearly 82% of Kentucky’s sports betting tax revenue — all signaled that the framework could force them to exit the Kentucky market rather than comply.

If those three operators were to leave, the regulated market would not simply shrink. It would effectively collapse, pushing bettors toward offshore and unregulated alternatives that generate no tax revenue for the state.

$40 Million in Tax Revenue on the Line

The financial stakes are specific. Written testimony submitted to the Kentucky House of Representatives in opposition to HB 904 warned the measure would cost the state more than $40 million in tax revenue every year. That money is not sitting in a general fund: it is currently directed toward teacher pensions, which makes the fiscal question a direct matter of retirement security for Kentucky educators.

Regulated sports betting markets exist in part because they redirect wagering activity away from illegal bookmakers and offshore sites. When major licensed operators exit a state, bettors do not stop betting — they migrate to unregulated platforms, and the state collects nothing. Kentucky’s situation illustrates a recurring tension in sports betting regulation: consumer protection measures that are too restrictive can undermine the very tax base those measures were designed to protect.

Tax Rates Under HB 904

The legislation brings newer product categories into Kentucky’s tax framework:

  • Prediction markets: a 14.25% tax, according to Legal Sports Report.
  • Fantasy sports: a 12.5% tax, with fantasy contests newly brought under the bill.
  • Fixed-odds horse racing: a 15% excise tax on the adjusted gross revenue of fixed-odds wagers on live horse racing, per the bill summary on LegiScan.

A tax rate alone rarely drives operators out of a market; structural compliance requirements that conflict with core product design are a different matter. The $1,000 mandatory wager acceptance rule adds another layer of operator friction, since sportsbooks routinely limit or ban winning bettors.

Where the Law Stands Now

HB 904 is now on the books. It was among the new Kentucky laws that took effect on July 15, 2026. The official bill record summarizes a central provision: prohibiting any operator conducting horse racing, sports wagering, or fantasy contests from participating in or contracting with any prediction market.

Reporting on the laws entering force notes that HB 904 does not add state-level regulations for prediction markets, and PBS coverage described the bill as taxing those markets without regulating them.

What This Means for Kentucky Bettors

For bettors who use DraftKings, FanDuel, or Fanatics, the operators’ warnings created real uncertainty: an exit would mean losing access to the apps they use most, along with the consumer protections that come with licensed operators. The age change directly affects a segment of users as well — anyone previously betting legally at 18, 19, or 20 loses access to licensed platforms under the new rules.

For readers tracking regulatory trends across states, Kentucky’s HB 904 is a clear example of how consumer protection goals and tax revenue goals can collide when a bill is not carefully calibrated.
