Google quietly updated its advertising policy on June 2, 2026, banning prediction market ads in Ohio. The move adds Ohio to a short but growing list of U.S. states where such ads are not allowed, with Nevada being the only other state currently on that list.
Google cited “the inherent complexities, speculative nature, and unique regulatory classification” of prediction market contracts as reasons for its policy restrictions. Advertisers who are permitted to run these ads elsewhere must hold all applicable financial, commodity, or gaming licenses.
The Ohio Casino Control Commission said it did not ask Google to make the change. Andromeda Morrison, the OCCC’s interim executive director, said in a statement that the commission “applauds Google for its efforts to ensure that marketing targeting Ohioans fully complies with Ohio law.”
Google first began allowing prediction market advertising across most U.S. states in January 2026, with Nevada as the sole exception at that time. Ohio’s addition in June marks a shift in how the platform is applying its rules on a state-by-state basis.
