Google to Ban Chrome Prediction Market Extensions August 1

Google will prohibit Chrome extensions facilitating real-money prediction market transactions starting August 1, 2026. This policy update coincides with increased legal scrutiny on prediction market platforms like Kalshi and Polymarket in the United States.

What Happened

Google has updated its Chrome Web Store rules to ban prediction market extensions that support real-money transactions, with enforcement scheduled to begin on August 1, 2026, according to Crypto News. The company stipulated that developers have until this date to comply with the revised policies.

The updated Developer Program policies explicitly state that browser extensions that “facilitate or enable real money transactions on predictive outcomes” will no longer be permitted on the Chrome Web Store. Non-compliant extensions could face enforcement action, including removal from the marketplace, after the deadline, Crypto News reported.
