Google Puts a New Prediction Markets Ban on Chrome

Google has expanded Chrome Web Store rules to ban extensions that facilitate real-money prediction markets, with enforcement starting August 1, 2026. The move creates a new distribution hurdle for platforms like Polymarket and Kalshi just as prediction-market volumes are hitting record highs. The article frames the decision as part of Google’s broader trust and data-privacy overhaul, while noting the apparent contradiction that Google Finance has been integrating prediction-market data from those same platforms. Although access through websites and mobile apps remains available, the policy may limit user acquisition and extension-based distribution, adding regulatory and platform risk to a fast-growing crypto-adjacent segment. The broader backdrop remains mixed: volumes are surging, but bans, app store removals, and legal challenges are intensifying across multiple jurisdictions.
