Google Bans Prediction-Market Ads in Ohio — Second State After Nevada, and Regulators Weren't Told First
Google updated its US prediction-markets advertising policy to prohibit ads for prediction-market contracts in Ohio, effective 2 June 2026. Ohio joins Nevada as the only states excluded since Google opened the category in January. The Ohio Casino Control Commission says it did not request the ban — adding a new, private-sector front to a fight that has so far run through courts and statehouses.
Google has updated its prediction-markets advertising policy to prohibit ads for prediction-market contracts and related products in Ohio, effective 2 June 2026. The change makes Ohio the second US state excluded from the category since Google opened it in January 2026, when the company began allowing prediction-market advertising in every state except Nevada. The eligibility rules elsewhere are unchanged: CFTC-registered Designated Contract Markets and National Futures Association-authorised brokerages can advertise, provided they hold Google certifications.
The notable detail is that Ohio's own gaming regulator did not ask for the ban. "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," OCCC interim executive director Andromeda Morrison said. Google acting ahead of — rather than in response to — a regulator's request suggests its policy team is tracking state-level enforcement posture and de-risking proactively: Ohio sent cease-and-desist orders to Kalshi, Crypto.com, and Robinhood in April 2025, making it one of the earliest state enforcers even though it never escalated to litigation.
The Ohio action adds a third front to a fight that has so far run through two: federal courts (the CFTC's six state preemption suits) and statehouses (Minnesota's felony ban, fifteen-plus state bills). Ad-platform policy is different in kind. Google is not a party to any litigation; it is making a private commercial judgement about regulatory risk, state by state. That matters operationally because paid search is a primary acquisition channel for every consumer trading product. A platform that wins its preemption case in federal court but cannot advertise in a state has won the legal argument and lost the growth channel. UK readers will recognise the pattern from the ASA and Google's UK gambling-ads regime, where certification gates and platform policy have long operated as a de facto second regulator alongside the Gambling Commission.
Two implications follow. First, the Nevada-plus-Ohio list is unlikely to stay at two — Google's stated logic applies at least as strongly to Minnesota, where operating a prediction market becomes a felony on 1 August unless the federal court intervenes. Second, the asymmetry hurts smaller operators most: Kalshi, Robinhood, and DraftKings have brand recognition and owned channels, while newer entrants relying on paid acquisition just lost their primary tool in an 11.8-million-person state. For Ohio residents nothing changes about platform access itself — what changes is what platforms are allowed to show them.

An Independent Integrity Body Found 7 Betting Irregularities at the World Cup. FIFA Said There Were None. The Clash Centres on Polymarket.
The Group of Copenhagen — the Council of Europe's independent match manipulation watchdog — raised seven yellow notices for potential betting irregularities during the 2026 World Cup, directly contradicting FIFA's all-clear published on Tuesday. The most troubling finding involves Polymarket: the platform opened a market on 2 July asking whether Folarin Balogun would play against Belgium — the same day Balogun received a red card, three days before FIFA publicly confirmed his ban was suspended. No equivalent markets were opened for any of the other 14 red cards at the tournament.
