Google Bans Prediction Market Advertising in Ohio as State Regulators Push Back on CFTC Oversight

Google has banned prediction market ads in Ohio. The policy update effective June 2 2026 makes Ohio the second US state after Nevada where such advertising is prohibited by the search giant.

The decision did not come at the request of Ohio gaming regulators. It reflects Google’s own assessment of the speculative nature and complex regulatory status of these products. Prediction market platforms maintain they operate as federally overseen exchanges under the Commodity Futures Trading Commission. State authorities continue to assert their right to treat event contracts as illegal gambling.

This development lands amid ongoing litigation. It highlights the friction between federal classification and state enforcement.

Google’s Policy Shift and Its Reach

In January Google began permitting prediction market advertising across the United States except in Nevada. The June 2026 update adds Ohio to that restricted list.

Google’s stated rationale cites the inherent complexities speculative nature and unique regulatory classification involved in trading prediction market contracts and related products. Advertisers must be licensed prediction market providers holding all applicable local financial commodity and gaming licenses including those required as part of Google’s certification process.

According to Google’s terms Nevada and Ohio are the only US jurisdictions where prediction market advertising is prohibited. This holds even as scores of states have issued cease-and-desist orders against platforms like Kalshi.

The ban covers ads for fixed-return contracts online gambling and online touting. For operators and platforms this restricts a key customer acquisition channel in a growing market.

From the supplier side after eighteen years across iGaming and sportsbook operations I see how platform visibility drives user onboarding. Losing Google in even one state forces a rethink on marketing budgets and compliance overhead.

Ohio’s Regulatory Stance and Legal Battles

Ohio regulators and litigators continue to defend the state’s legal sports betting framework. Gov. Mike DeWine a term-limited Republican who helped spearhead legalization in 2023 has publicly lamented its social impacts in recent months.

Two days after Google’s announcement Ohio attorneys responded to a Kalshi lawsuit seeking to overturn a cease-and-desist order. They attacked the claim that sports event contracts qualify as swaps or derivative contracts used for hedging.

Ohio attorneys argued that allowing sports events contracts which the Ohio Casino Control Commission considers illegal gambling to be regulated as swaps at the federal level would render much of the language of the Commodity Exchange Act meaningless.

Ohio sent cease-and-desist letters to Kalshi Robinhood and Crypto.com in April 2025. Kalshi sued the OCCC and the state attorney general’s office. A federal judge in Ohio denied the preliminary injunction request.

Andromeda Morrison OCCC interim executive director stated in an email that the Ohio Casino Control Commission did not solicit any particular action from Google but applauds Google for its efforts to ensure that marketing targeting Ohioans fully complies with Ohio law.

Kalshi’s Multi-Front Legal Defense

Kalshi is currently embroiled in 18 federal and state lawsuits. These defend its assertion of federal oversight by the CFTC.

The CFTC has sided with the platform suing seven different states that have attempted to shut down the platforms and their controversial sports event contracts.

In late May the CFTC sued Rhode Island to block enforcement of a ban on Polymarket. Minnesota where sports betting is not legal became the first state to ban prediction markets in May through an omnibus public safety bill.

These cases test the boundaries of CFTC authority versus state gaming regulation. The outcomes will shape where and how prediction markets can operate and advertise.

The Google ban adds a practical layer. Even without direct state pressure platforms lose access to one of the most effective digital advertising channels.

Risks and Counterarguments in the Current Landscape

One risk is that Google’s policy could spread. If more states align on enforcement or if Google expands its prohibited list the advertising squeeze tightens further.

Prediction market executives counter that their platforms function as CFTC-regulated exchanges rather than gambling operations. They point to the federal framework as preemptive over state bans.

Yet the volume of litigation 18 cases and counting shows the assertion faces stiff resistance. Ohio’s arguments about preserving the meaning of the Commodity Exchange Act illustrate a core tension. Treating event contracts as swaps could undermine distinctions the law was designed to maintain.

From an operational standpoint this uncertainty stalls commercial decisions. Marketing teams must navigate shifting state rules while platforms burn resources on legal defense. In my experience across European regulated markets operators price in regulatory overhead faster than most expect but prolonged litigation adds friction that slows user growth.

Another limitation is the speculative nature Google itself flags. Without clear nationwide resolution prediction markets remain in a gray zone that deters mainstream advertisers and partners.

The Bottom Line is that Google’s ban in Ohio reinforces the fragmented regulatory environment facing prediction markets. With Kalshi locked in lawsuits across 18 fronts and states like Minnesota enacting outright bans the path to broader acceptance is contested. Operators and platforms should track how these cases resolve particularly around CFTC preemption and event contract classification.
