Google Tightens Gambling Ad Access and Prediction Market Extensions

Google has set two new compliance deadlines for gambling-related businesses. Chrome will act first, followed by wider certification checks across Google Ads.

From September 14, 2026, every account seeking permission to advertise under Google’s Gambling and games policy will have to demonstrate good policy health.

Policy History Moves to the Front of Certification

According to Google, the update in July broadens the certification requirements that were introduced in March across all categories included in the policy. The company’s notification does not state any numeric compliance requirement. However, it emphasizes that the past behavior of the advertiser is crucial during the certification process. Repeated certificate revocations or repeated gambling policy violations can block new applications and may lead to existing certifications being withdrawn.

Manager Accounts face broader consequences. MCCs with repeated online gambling certificate revocations, as well as managed accounts repeatedly flagged for gambling violations while using a certificate, may lose eligibility to apply for new certificates. Existing certifications may also be revoked.

Domain Rules Come Into Focus

Google also reiterated its domain requirements for gambling certification:

Websites hosted on free subdomains are ineligible;
The domain must be directly owned and controlled by the applying business;
Domains unrelated to gambling cannot receive standalone certification.

Google presented these conditions as existing application requirements rather than new domain rules. They were repeated in the July notice for emphasis.

Chrome Closes an Extension Route

The Chrome Web Store will begin enforcing its updated Developer Program Policies on August 1, 2026. Google has explicitly added predictive markets to the prohibited products covered by its Chrome Web Store rules.

The prohibition pertains to any extensions that facilitate or enable real-money transactions based on predictive outcomes. The rule does not ban prediction market websites. It removes the Chrome Web Store as a distribution channel for extensions that support real-money transactions on predicted outcomes.

The wider update also limits data collection to an extension’s disclosed purpose, strengthens disclosure requirements, and prohibits tools designed to bypass safeguards used by AI-powered services.

Google Links Platform Access to Business Conduct

The two changes apply to distinct areas within the distribution network. Google Ads is restricting access to paid gambling traffic. The Chrome Web Store is restricting the distribution of extensions that support real-money prediction market transactions.

Review is moving beyond the individual advertisement or extension listing. Account history, MCC structures, domain control, and the product’s core function can now determine whether a business retains access. Repeated violations may affect an MCC’s eligibility for new certificates and put existing approvals at risk. Prediction market businesses using transactional Chrome extensions may also lose access to the Chrome Web Store as a distribution channel.
