The operating room for crypto-adjacent prediction market platforms like Kalshi and Polymarket is narrowing rapidly. This time, the crackdown comes not just from courts or financial regulators, but from the tech giant behind the world’s most popular web browser: Google has updated its Chrome Web Store policies to ban extensions that facilitate real-money transactions on event prediction outcomes.
New Chrome Web Store Policy
According to an update to Google’s Developer Program policy, browser extensions that “facilitate or enable real-money transactions on predictive outcomes” will no longer be permitted on the Chrome Web Store. Developers have until August 1, 2026, to comply, after which non-compliant extensions face enforcement actions, including removal from the marketplace.
While Google did not single out specific platforms in its updated policy, the timing coincides with escalating legal scrutiny against prediction market operators in the United States, particularly regarding sports event-based contracts.
Mounting Legal Battles
In New York, Judge Analisa Torres denied Kalshi’s request for a stay in the state lawsuit, allowing the case to proceed. The court ruled that New York gambling laws apply to Kalshi’s sports event contracts. Governor Kathy Hochul responded forcefully: “Gamble with our laws and you will lose. Just ask Kalshi.” She affirmed that her administration and the Attorney General will continue to pursue prediction market platforms deemed to be violating state law - including separate lawsuits already filed by New York against Coinbase and Gemini on similar allegations.
In Europe, ESMA issued warnings regarding Polymarket over regulations that could potentially trigger access bans for retail investors. On top of that, Kalshi faces a dispute with Spotify, which demanded Kalshi pull its branding following a fake-streaming scandal involving a music-related prediction market on the platform.
What stands out about these developments is not any single decision, but the broader pattern: financial regulators, state courts, European authorities, and now a tech giant like Google are all closing loopholes from different angles almost simultaneously. For the prediction market industry, once viewed as operating in a comfortable gray area, maneuvering space appears to be shrinking from all sides, not just on a single front.
