Google Reclassifies Prediction Markets and Opens U.S. Ad Access

Google has updated its advertising policy to allow prediction market platforms to direct ads to Americans. The company now treats prediction markets as financial services instead of gambling, a change that broadens where and how those ads can appear.

The update benefits platforms such as Polymarket and Kalshi, which have long argued their products function as financial instruments rather than betting services. Under the new policy, ads can run in jurisdictions where gambling promotions face limits or outright bans.

Google outlined clear criteria for platforms seeking prediction market status. To qualify, Google requires that platforms “platforms facilitate the listing of or provide customer access Exchange-Listed Event Contracts related to economics, sports or current events.”

Authorization as a Designated Contract Market through the Commodity Futures Trading Commission is not mandatory. Platforms may also qualify by registering with the National Futures Association as a Futures Commission Merchant and offering third party access to Designated Contract Markets.

Google recently partnered with Kalshi and Polymarket to use data from both platforms inside Google financial tools. A company spokesperson said the advertising reclassification decision had no connection to those agreements.

Prediction markets have consistently positioned themselves outside traditional gambling frameworks. That stance has allowed them to operate in states with strict betting laws while also facing lower tax burdens than sportsbooks.

Market interest has grown quickly. Recent industry analysis suggests prediction markets could eventually handle trillions of dollars in annual trading volume, driven by contracts tied to sports, economics, and current events.

Despite the broad policy shift, Google carved out a major exception. The new advertising classification does not apply in Nevada. Prediction markets have faced strong resistance there from regulators and established gambling interests.
