Google Blocks Prediction Market Ads in Ohio as Regulatory Battle Over Kalshi Heats Up

Google has pulled Ohio from its approved list of states for prediction market advertising, implementing the restriction on June 2, 2026 in response to the ongoing legal dispute between Ohio officials and prediction market platforms operating under federal CFTC licenses. The move blocks operators like Kalshi from running paid Google campaigns targeting Ohio users, cutting off one of the most efficient digital marketing channels for platforms competing in the prediction market space.

The Google policy covers prediction market advertising specifically — campaigns promoting event-based contracts tied to sports outcomes. Google’s financial products advertising policies require that advertisers comply with applicable laws in the regions where their ads run, and with Ohio’s attorney general and casino control commission having taken active enforcement positions against Kalshi, the legal landscape in the state no longer clears Google’s threshold for advertising approval.

Ohio Has Been Among the Toughest States on Prediction Markets

Ohio regulators have argued that Kalshi’s sports event contracts are functionally equivalent to sports betting, requiring state gambling licenses the company does not hold. The state’s casino control commission and attorney general’s office have both pursued enforcement against Kalshi, and the CFTC countered by filing its own federal lawsuit seeking to block Ohio from applying its gambling laws to federally regulated exchanges.

The dispute is now before the Sixth Circuit Court of Appeals, where former CFTC and SEC chairman Gary Gensler filed an amicus brief backing Ohio on June 12. Gensler argued that the 2010 Dodd-Frank Act never authorized federal preemption of state sports betting laws, opposing the current CFTC’s position. Multiple circuits are now handling prediction market jurisdiction cases, and legal observers say a Supreme Court ruling is increasingly likely as the conflicts deepen.

What It Means for Sports Bettors in Ohio

Prediction market platforms remain technically accessible to Ohio users — the legal battle is between regulators and operators, not an end-user ban. However, the advertising restriction means fewer Ohio residents will encounter prediction market platforms through search. Users who independently seek out platforms like Kalshi can still access them, but the lack of Google advertising reduces organic discovery significantly.

For Ohio sports bettors looking for traditional sportsbook options, the state has a fully regulated and highly competitive market. Major operators including FanDuel, DraftKings, BetMGM, and Caesars have been active in Ohio sports betting since the market launched in January 2023. These platforms operate under full state licensing and are not subject to any advertising restrictions.
