Prediction Markets in Kentucky

Kentucky's Event-Contract Tax (HB 757)

In 2026 Kentucky enacted HB 757, a state-level tax on prediction-market event contracts. It starts on January 1, 2027 and is being challenged in court. Kentucky has enacted a state tax on event-contract activity (HB 757), starting January 1, 2027; the law is being challenged in court.

The structural design is novel: rather than asserting a state gambling-law jurisdiction over CFTC-regulated platforms (the approach taken by Nevada, Mississippi, and others), Kentucky's law accepts that prediction markets are federally regulated and instead imposes a transactional tax on KY-resident activity.

Industry observers expect a significant lobbying push from both the prediction market industry (which generally supports clear state-level frameworks over enforcement uncertainty) and the licensed sportsbook industry (which generally supports any structure that increases prediction market operating costs).

Kentucky's Established Mobile Sports Betting Market

Kentucky launched legal mobile sports betting on September 28, 2023 under House Bill 551, signed into law by Governor Andy Beshear. The state authorizes up to 27 mobile sportsbook licenses (3 per licensed retail track operator), and major operators FanDuel, DraftKings, BetMGM, Caesars, ESPN BET, Fanatics, Bet365, and Circa Sports are all live.

Kentucky imposes a 14.25% tax on adjusted gross gaming revenue from mobile sports betting and a 9.75% tax on retail. The market generates approximately $40-50M in state tax revenue annually. The Kentucky Horse Racing Commission oversees sports wagering as part of its broader pari-mutuel and gaming jurisdiction.

The presence of an established legal sportsbook market is part of why Kentucky's approach to prediction markets has been more nuanced than states without legal sports betting. Rather than asserting that prediction markets are illegal, KY policy makers are exploring whether they can be taxed as a separate revenue stream alongside the licensed sportsbook regime.

Best Platforms for Kentucky Residents

OG.com is our top pick for Kentucky in 2026. Crypto.com's CFTC-regulated sports-first prediction market combines a 4-leg parlay builder, social trading feed, and live in-game contracts — and new traders can trade $25 and get $50 in rewards with code RANKPREDICTS. Kalshi remains a strong runner-up for the deepest non-sports catalog and lowest published fees.

Polymarket US is not named in any pending Kentucky enforcement or recovery action and offers the lowest fees in the category for politics and crypto markets.

DraftKings Predictions and FanDuel Predicts are interesting in KY because both companies operate licensed Kentucky sportsbooks. Users can keep sportsbook accounts for traditional bets and Predictions accounts for combo contracts and longer-dated futures.

Tax Considerations for Kentucky Residents

Kentucky has a flat state income tax of 4.0% (after recent KY tax reform reducing the rate from prior 5.0% level). Net gains from prediction market trading are taxable at federal level plus the KY flat rate. Kalshi provides a profit-and-loss statement for your trades; platforms' 1099s mainly cover interest, rewards and crypto transfers.

If the proposed Kentucky transactional tax on event contracts becomes law, KY traders would owe an additional state-level tax on each qualifying transaction or net activity period (depending on final bill structure).

What could change the status

Dates we are watching: Nevada's responses to the Robinhood and Crypto.com Supreme Court petitions are now due November 13 and 16, 2026 (both extended in October), and Kalshi's response to New Jersey's petition is due November 9, 2026 (deadlines can be extended); the earliest the Supreme Court could act on the petitions is a conference in December 2026 or January 2027 (our estimate, not a scheduled date). We re-check this page when any of these happen and log the change above.
