Google has updated its Chrome Web Store Developer Program Policies to prohibit real-money prediction market trading, expanding its rules for regulated goods and services. The policy changes were announced on July 1, 2026, and will take effect on August 1, 2026.
The update is part of a broader effort to strengthen user privacy, improve transparency, and enhance security across the Chrome extension ecosystem. Developers have one month to ensure their extensions comply with the revised policies or risk removal from the Chrome Web Store.
Under the new rules, Chrome extensions can no longer provide or facilitate access to real-money prediction markets. This includes extensions that execute trades, connect users to prediction market contracts, or automate participation in event-based wagering. The policy applies specifically to Chrome Web Store extensions, not to prediction market platforms or their websites.
Google Tightens Privacy and AI Extension Requirements
Alongside the prediction market restrictions, Google introduced stricter requirements governing data collection and AI-related extensions. Developers must now limit data collection to information that is strictly necessary for an extension’s stated functionality and clearly disclose all data practices. Users must also be informed if an extension changes how it collects or uses data after installation.
Google also expanded its prohibited content policies to ban extensions designed to bypass or disable safety protections on AI platforms.
- Announcement date: July 1, 2026
- Enforcement begins: August 1, 2026
- Prediction market extensions: Real-money prediction market extensions are prohibited on the Chrome Web Store.
- Data collection: Extensions may collect only the minimum data required for their stated purpose.
- Transparency: Developers must clearly disclose data collection practices and notify users of material changes.
- AI restrictions: Extensions that circumvent AI safety or usage protections are prohibited.
The policy is expected to have implications for crypto-related prediction market services that rely on browser extensions for wallet connectivity or trading functionality. While companion Chrome extensions may need to be redesigned or removed, users can continue accessing prediction market platforms through their websites where permitted by local regulations.
Google said the changes are intended to maintain a secure and trustworthy Chrome extension ecosystem while ensuring developers follow clearer standards around regulated services, user privacy, and responsible software development.
The latest policy update follows a series of Chrome and AI-related initiatives by Google in recent months. In March, Google patched a high-severity Chrome vulnerability affecting Gemini AI integrations, while in May, Google Cloud partnered with Solana to launch Pay.sh, enabling stablecoin payments for AI agents. The latest Chrome Web Store rules further reinforce Google’s focus on platform security, responsible AI, and user protection.
