Google adds explicit restrictions on prediction market extensions
Google said on July 1, 2026 that it is updating Chrome Web Store developer policies as part of its broader effort to maintain a high-quality, trusted, and secure ecosystem for both developers and users. For the crypto sector, the most consequential revision is under the policy covering regulated goods and services. Google expanded the wording to explicitly classify prediction markets as prohibited products.
Under the updated rule, extensions that facilitate or support real-money transactions tied to prediction outcomes are not allowed in the Chrome Web Store. While Google did not single out specific platforms or tokens, the language draws a clear boundary around browser-based tools that could be used to access or streamline regulated prediction market activity involving real-money exposure.
Data collection rules narrowed to a single disclosed purpose
Google also revised its limited use policy governing extension data collection. The new standard requires that any user data collected by an extension be used strictly for the single purpose disclosed by that extension. Collecting data for any additional or unrelated purpose is prohibited under the updated policy framework.
At the same time, the company tightened its disclosure requirements. Developers must now provide prominent notice of all data collection practices, regardless of whether the collected data is closely related to the extension’s stated single purpose. Google said the change is intended to improve transparency and give users a clearer understanding of how their data is handled inside the extension ecosystem.
Another notable addition is an ongoing disclosure obligation. If a developer changes data handling practices at any point after the initial installation, that change must be proactively disclosed to users. In practical terms, the update raises the compliance threshold not only for what extension developers can collect, but also for how clearly and consistently they communicate those practices over time.
New AI-related prohibition and August 1 enforcement date
Beyond prediction markets and privacy rules, Google introduced a new clause under its malicious and prohibited products policy. The company said extensions specifically designed to circumvent safeguards, usage limits, or other protections imposed by AI-powered services will be banned. The move extends Chrome Web Store enforcement into a new category of products that target AI system restrictions.
Google framed the policy package as part of a broader trust and safety effort. According to the company, stronger standards around data collection, clearer lines around prediction markets, and explicit limits related to AI protections are necessary to keep the Chrome Web Store honest, useful, and safe.
Google advised developers to review their active extensions against the updated rules as soon as possible. The new policies will become mandatory on August 1, 2026. After that date, extensions found to be non-compliant may face enforcement action from the Chrome Web Store.
