Catenaa, Monday, November 10, 2025- Google will begin incorporating prediction market data from Kalshi and Polymarket into Google Finance tools, potentially exposing millions of users to odds derived from online event contracts.
The platforms allow users to place wagers on outcomes ranging from elections and financial results to entertainment events. Google said the integration will let users “ask questions about future market events” and view aggregated probabilities over time.
Kalshi operates under Commodity Futures Trading Commission regulation, while Polymarket has faced restrictions in the U.S. and other countries. Both companies argue their contracts are commodities rather than traditional gambling, though state regulators and lawmakers have challenged that classification.
Recent research suggests up to 25% of Polymarket’s trading volume may be self-directed by users, raising concerns about market manipulation. Legal disputes over contract criteria and payouts have also drawn scrutiny.
Investments from Intercontinental Exchange, Founders Fund, and backing from Donald Trump Jr. have boosted Polymarket’s valuation to around $8 billion. Kalshi’s valuation is estimated at $5 billion following funding rounds led by Andreessen Horowitz, Sequoia Capital, and Paradigm.
Both companies continue to navigate evolving regulatory frameworks in the US, where enforcement decisions under the Trump administration have shifted in their favor.
Google has not detailed how the integration will function or whether users will link directly to the platforms.
The move represents a significant step in mainstreaming event contract data for financial analysis, despite ongoing legal and regulatory uncertainty.
