Google Bans Prediction Market Advertising in Ohio, Making It the Second State Blocked After Nevada

Google has expanded its restrictions on prediction market advertising to include Ohio, making the Buckeye State the second US jurisdiction where the tech giant has blocked ads promoting prediction market platforms. The move follows a similar ban that went into effect in Nevada earlier in the year, and it reflects the growing regulatory and reputational pressure that prediction market operators face as state authorities and federal regulators debate whether their products constitute legal gambling.

Google’s advertising policies give it significant power to shape the user acquisition strategies of prediction markets platforms. Paid search and display advertising through Google are among the most effective digital marketing channels, and losing access to those channels in a state can meaningfully reduce a platform’s ability to attract new users who are searching for sports betting, trading, or event prediction options. For platforms that rely heavily on paid acquisition, the Ohio ban compounds a pattern of growing restrictions on their marketing activities.

Why Ohio and Nevada?

Ohio and Nevada are not accidental choices in Google’s restriction policy. Both states have taken active regulatory stances toward prediction markets. Ohio’s gaming regulators have been among the more vocal in questioning whether prediction market sports contracts fall within their jurisdiction and whether platforms like Kalshi promo code, Polymarket promo code, and others are operating legally in the state. Nevada, meanwhile, has deep gaming regulatory infrastructure through the Nevada Gaming Control Board and Gaming Commission, and the state has been particularly attentive to whether new financial products overlap with activities that require gaming licenses.

Google’s policies in the gambling and gaming advertising space are designed to align with the regulatory environment in each jurisdiction. When regulators in a state signal that a product category is under legal scrutiny or may be operating without proper authorization, Google has shown a willingness to restrict advertising for those products in that state proactively, rather than waiting for a definitive regulatory determination.

Prediction Markets Under Mounting Pressure

The Google restrictions are the latest in a series of regulatory and legal challenges for prediction market operators in the United States. Kalshi review has faced lawsuits from multiple states, including a case filed by New Mexico that accused the platform of operating unlicensed online sports betting. The National Advertising Division recently referred Kalshi to regulators after it declined to participate in a review of its influencer advertising practices. Separately, Kalshi has been quietly removing gambling-related language from its federal trademark filings as legal pressure mounts.

At the same time, platforms like Robinhood promo code have been building their own regulated prediction market infrastructure. Robinhood recently routed its World Cup prediction markets through Rothera, its own CFTC-licensed exchange, signaling a shift away from relying solely on Kalshi’s regulatory permissions. DraftKings, FanDuel, and other traditional sportsbook operators have also entered the prediction market space with their own CFTC-compliant products, adding competitive pressure to the standalone prediction market platforms that are now facing more advertising restrictions.

The cumulative effect of these developments — regulatory scrutiny, state lawsuits, advertising restrictions, and better-capitalized new entrants — is creating a more challenging environment for prediction market operators that positioned themselves as financial products rather than gambling operations. The Google ban in Ohio is one more piece of that pressure, narrowing the marketing runway for platforms in a state where the legal status of their products remains unsettled.

What Bettors in Ohio Should Know

Ohio residents who use prediction market platforms are not directly affected by the Google advertising ban — existing users can continue accessing their accounts. The restrictions apply to Google’s ad inventory, meaning platforms cannot pay to place ads targeting Ohio users through Google’s systems. Organic search results, direct app downloads, and other marketing channels remain available.
