- Google will ban prediction market extensions from the Chrome Web Store starting August 1, 2026.
- The updated Chrome Web Store policy prohibits extensions that facilitate real-money prediction market transactions.
- The move comes as Polymarket and Kalshi face growing legal and regulatory scrutiny across several U.S. states.
On August 1, 2026, Google plans to remove prediction market extensions from the Chrome Web Store, which is a significant step forward for the rapidly expanding prediction market sector. The action is taken in response to growing regulatory scrutiny of platforms like Polymarket and Kalshi in the US because of issues with contracts for sporting events.
Google, one of the world’s largest technology companies and the developer of the Chrome browser, clarified in its latest update to the Chrome Web Store Developer Program policies that extensions enabling real-money prediction market transactions will no longer be permitted on its platform. The revised policy states that “Extensions that facilitate or enable real money transactions on predictive outcomes are not allowed.”
The business also stated that the updated policy will go into effect on August 1, 2026. After that date, Chrome extensions that don’t follow the new guidelines risk being taken down from the Chrome Web Store.

The policy update is a part of Google’s larger initiative to strengthen its marketplace policies and guarantee that extensions adhere to platform standards and relevant legal requirements. The new regulations are anticipated to affect services that use browser extensions to support real-money prediction markets, even though the corporation did not name any particular prediction market sites.

The announcement coincides with growing legal and regulatory obstacles that prediction market operators must deal with. Regulators in a number of U.S. states have recently taken notice of platforms like Polymarket and Kalshi due to claims that some of their products resemble illegal sports betting.
Spotify, a music streaming service, also voiced concerns earlier this week after learning that its logo had been used in prediction markets without permission. The business requested that prediction market platforms take down its branding and make it clear that there was no collaboration between the two parties.
Kalshi Faces Fresh Legal Pressure As New York Lawsuit Moves Forward
The disagreement arose after Spotify removed over 500,000 fake plays that momentarily increased the popularity of Malcolm Todd’s song “Earrings.” According to reports, Kalshi had settled a market involving those streaming numbers.
New York, meanwhile, keeps putting more pressure on Kalshi. “Gamble with our laws and you’re going to lose,” said New York Governor Kathy Hochul after the state won a lawsuit. Ask Kalshi, please. New York’s gambling rules apply to some sports-related prediction contracts, according to state regulators.
Kalshi’s request for a preliminary injunction was recently denied by a federal judge, allowing New York’s lawsuit against the corporation to proceed. According to the verdict, the platform’s contracts for sporting events might be subject to the state’s gambling regulations.
