Google Finance has expanded its market tracking capabilities by adding prediction market data from regulated platform Kalshi and blockchain-based operator Polymarket. The integration allows users to query future events through natural language searches and receive real-time market probabilities alongside historical trend data.
Users will be able to ask questions such as “What will GDP growth be for 2025?” directly in the Google Finance search box to access current market odds and visualize how those probabilities have shifted over time. The feature surfaces crowd-based forecasts on events ranging from economic indicators to political outcomes, positioning prediction market data alongside traditional financial metrics like stock quotes and bond yields.
Expanding Mainstream Adoption of Prediction Markets
The partnership represents one of the first major integrations of prediction market data into a mainstream consumer technology platform. Kalshi operates under regulatory oversight from the U.S. Commodity Futures Trading Commission (CFTC), offering event contracts on sports, politics, and economic outcomes. Polymarket, which runs on the Polygon blockchain, gained attention through its decentralized prediction markets covering politics, sports, and cultural events.
Both platforms have seen significant growth in recent months. Polymarket secured an investment from Intercontinental Exchange that valued the company at approximately $9 billion, while Kalshi raised $300 million at a $5 billion valuation from investors including Sequoia Capital and Andreessen Horowitz.
Weekly prediction market volumes exceeded $2 billion for the first time in late October, driven primarily by sports and political event contracts. Polymarket’s monthly volume, active trader count, and new market creation all reached record levels in October as institutional and retail interest accelerated.
Broader Google Finance Enhancements
The prediction market integration forms part of a wider Google Finance platform overhaul that includes several AI-powered features. Google introduced “Deep Search,” which uses the company’s Gemini AI model to generate comprehensive, cited answers to complex financial questions. The update also adds real-time earnings call transcripts and summaries for public companies.
Google confirmed the enhanced platform will expand beyond the United States, beginning with India, as the company works to make financial data more accessible globally. The prediction market data will initially launch for Google Labs users before rolling out more broadly in the coming weeks.
Growing Institutional Interest in Event Contracts
The financial services industry has shown increasing interest in prediction market infrastructure. Mobile brokerage Robinhood partnered with Kalshi in August to offer contract trading on professional and college football, subsequently expanding those offerings. Robinhood CEO Vlad Tenev characterized the prediction market sector as “on fire” during the company’s third-quarter earnings call.
In October, Polymarket and Kalshi became the first officially licensed prediction markets of the National Hockey League, representing a milestone in sports league adoption of alternative wagering formats. The development puts pressure on established sports betting operators like DraftKings and FanDuel to explore similar offerings.
Polymarket, which was effectively barred from operating in the United States following a 2022 CFTC enforcement action, has since acquired a Designated Contract Market (DCM) license and plans to relaunch U.S. operations by the end of November. The platform recently announced a fee structure of $0.01 per $100 in contracts, significantly below Kalshi’s average fee of $1.20 per $100 in contracts.
“Our goal is to make event data accessible to everyday investors through trusted platforms like Google Finance.”
Industry analysts suggest prediction markets are evolving beyond their original scope to function as broader information hubs spanning politics, business, economics, sports, and culture. The integration of this data into Google’s search infrastructure could accelerate public familiarity with prediction market mechanics and crowd-sourced forecasting methodologies.
Cryptocurrency exchange Gemini is reportedly preparing to launch its own prediction market contracts pending regulatory approval, which would add another major player to the growing sector. MetaMask confirmed plans in October to integrate Polymarket into its application as part of its strategy to serve as a gateway for decentralized finance tools.
The regulatory landscape for prediction markets in the United States remains under development, with debate ongoing about how event contracts should be classified. Kalshi’s CFTC-regulated model contrasts with Polymarket’s decentralized approach, though both platforms are gaining traction among investors exploring event trading as a hedge against macroeconomic uncertainty.
