Breaking: Google to Ban Prediction Market Extensions Amid Increased Scrutiny of Polymarket, Kalshi

Tech giant Google has revealed its updated policy for the Chrome Store, which includes a prohibition of prediction market extensions. This comes as platforms such as Polymarket and Kalshi face increased crackdowns by state regulators over claims that they are operating as illegal sports betting platforms.

Google To Prohibit Prediction Market Extensions

In the latest update to its Developer Program policies, Google announced that it is expanding its language to explicitly include predictive markets as prohibited products. “Extensions that facilitate or enable real money transactions on predictive outcomes are not allowed,” the blog post read.

The tech giant further stated that enforcement for these updated policies, which include the ban on prediction markets, will begin on August 1, 2026. “Extensions found out of compliance after this date may face enforcement action from the Chrome Web Store,” it added.

This comes as prediction market platforms such as Polymarket and Kalshi come under heavy scrutiny. As CoinGape reported, music streaming platform Spotify challenged these platforms, asking them to take down its logo and clarify that they had no existing partnership with Spotify.

This came after Spotify had identified and removed over 500,000 artificial streams that had made Malcolm Todd’s song “Earrings” one of the most popular on its charts. Kalshi notably settled a prediction market based on these artificial streams.

NY Governor Calls Out Kalshi

Commenting on the win in her state’s case against prediction market platform Kalshi, New York Governor Kathy Hochul said, “Gamble with our laws and you’re going to lose. Just ask Kalshi.” The state’s Attorney General earlier accused Kalshi of trying to circumvent the state’s laws and ended up losing in court.

“Governor Kathy Hochul and I will continue to hold all gambling platforms accountable — including prediction markets,” she said. As CoinGape reported, Judge Torres rejected Kalshi’s preliminary injunction against New York over gambling laws.

The judge ruled that New York state gambling laws apply to Kalshi’s sports-related event contracts, paving the way for New York’s lawsuit against Kalshi to proceed. It is worth noting that New York has already sued Coibase and Gemini, alleging that their prediction market platform operates as an illegal, unlicensed gambling business.
