Google Finance to Integrate Data from Kalshi and Polymarket Prediction Markets

Google is adding a new kind of market signal to its finance search results, not stock prices, not analyst forecasts, but real-time odds from prediction markets.

The company has struck a deal with Kalshi and Polymarket, two platforms known for letting users trade on the outcome of real-world events, from elections to economic data releases.

The move brings prediction market data into a mainstream setting, a big shift for an industry often dismissed as “gambling with a finance wrapper.”

What Google Is bringing to finance search

Under the partnership, when users search for certain future-focused queries, say, chances of a Fed rate cut, the outcome of an election, or whether GDP will rise next quarter, Google Finance will surface the live probability data coming from Kalshi and Polymarket.

No financial details about the agreement were disclosed.

Google framed the move as a way to help users “harness the wisdom of the crowds,” positioning prediction markets as another type of signal alongside analyst projections or poll data. Instead of waiting for surveys or quarterly reports, users will see continuously updating odds based on active markets.

Both platforms have seen record activity in 2024 and 2025, with Polymarket gaining attention for its crypto-based markets and Kalshi operating as a CFTC-regulated exchange in the U.S.

While sports markets have driven much of the recent volume, both companies have been working to shift public perception toward “information markets,” tools that reflect real-time sentiment across politics, economics, weather, and more.

A turning point for prediction markets?

Prediction markets have long lived in a grey zone: popular with traders, useful for journalists, but not fully embraced by traditional finance.

During the recent U.S. elections, both platforms saw heavy activity, and their odds were cited by major media outlets as faster, more responsive signals than polling averages.

The integration with Google marks one of the first times a major tech company has plugged live prediction market data directly into a consumer-facing product.

It also fits into Google’s broader effort to surface more probabilistic and real-time data inside Search, something increasingly powered by AI-driven forecasting tools.
