Google Finance integrates Kalshi and Polymarket data in first prediction market rollout

Google Finance has integrated real-time data from US-based prediction markets Kalshi and Polymarket, incorporating their prediction markets insights alongside traditional financial instruments.

The move represents Google’s first entry into prediction-based financial tracking, allowing users to view live major events such as elections, inflation reports, and macroeconomic outcomes directly on its platform.

The announcement, published on Google’s blog, introduced the feature as part of a broader update that also includes a Deep Search upgrade, enhanced corporate earnings tracking, and service expansion in India. “The new, AI-powered Google Finance is built to help you make sense of the financial world,” the company said.

Prediction markets join mainstream platforms

Kalshi operates under the supervision of the US Commodity Futures Trading Commission (CFTC), while Polymarket runs on blockchain infrastructure outside the regulated derivatives sector. Their inclusion on Google Finance introduces decentralized forecasting tools to a wider base of investors and analysts.

Google’s integration will allow users to “ask questions about future market events and harness the wisdom of crowds,” according to the company. The rollout is expected over the coming weeks.

Industry analysts said that making event-based data visible alongside equities, bonds, and commodities may help refine market sentiment analysis. Prediction contracts typically respond faster to political and economic developments than traditional assets, offering traders early insights into potential shifts in expectations.

Industry investment and market growth

Prediction markets have drawn growing institutional investment. Polymarket recently raised $2 billion from Intercontinental Exchange, the parent company of the New York Stock Exchange, valuing it at $9 billion. Kalshi has raised $300 million from Sequoia, Andreessen Horowitz, and Coinbase Ventures, giving it a $5 billion valuation.

The National Hockey League recently became the first professional sports league to partner with both Kalshi and Polymarket. “Teaming up with the NHL is an important milestone for Kalshi and the industry at large,” Kalshi CEO Tarek Mansour said in a statement. “It should be clear now – prediction markets are here to stay.”

Regulatory and legal landscape

Kalshi’s federally regulated model contrasts with Polymarket’s decentralized structure, which previously drew CFTC enforcement action. As these platforms expand into sports and entertainment markets, regulators and sportsbooks are confronting new compliance questions.

Several states, including Maryland, Massachusetts, Nevada, New Jersey, New York, and Ohio, are litigating whether sports event contracts offered by prediction markets constitute illegal sports betting. Regulators have also cautioned licensed sportsbooks that offering event contracts may jeopardize their operating licences.

Analysts suggest that as mainstream platforms like Google adopt prediction market data, regulators may face increasing pressure to clarify policy boundaries between event futures and traditional betting products.
