Yahoo Finance Turns To Polymarket For Exclusive Prediction Market Data Integration
Yahoo Finance is joining the growing wave of mainstream finance platforms adopting blockchain-based prediction data, after forming an exclusive partnership with Polymarket to integrate real-time market probabilities into its website.
The collaboration marks a notable expansion of prediction markets into traditional finance, allowing Yahoo Finance’s vast global audience—more than 150 million monthly visitors—to access crowd-sourced forecasts on politics, markets, and major world events.
How The Partnership Expands Prediction Market Reach
Polymarket announced the partnership on X on Wednesday, confirming it had become Yahoo Finance’s “exclusive prediction market partner.”
The company also shared a short promotional video featuring The Weeknd and Playboi Carti’s ‘Timeless’.
Yahoo Finance General Manager George Leimer said the company aims to help investors make better-informed decisions through this integration.
“This is an emerging area of finance that's becoming increasingly relevant to investors, and we’re focused on giving them trusted data and context to make smarter decisions.”
A new “prediction markets hub” will roll out on Yahoo Finance in the coming months, featuring Polymarket’s probability data for key political, economic, and financial outcomes.
Each forecast will appear alongside related articles, quotes, and analysis from Yahoo Finance and its partners, offering users a new dimension of data-driven insights.
Polymarket’s Rapid Growth And Institutional Backing
Polymarket’s partnership with Yahoo Finance follows its growing profile in the prediction markets space.
The platform recently revealed that Intercontinental Exchange (ICE)—the owner of the New York Stock Exchange—plans to invest up to $2 billion in the company.
ICE Data Services already supplies Yahoo Finance with its global market and index coverage.
Valued at around $9 billion, Polymarket has seen record growth this year.
In November alone, it has already recorded about $1.4 billion in trading volume, putting it on track to surpass October’s record of $3.01 billion, according to data from The Block.
Polymarket’s crypto-native model allows users to place bets on real-world outcomes using Circle’s USDC stablecoin, with trades settled transparently on the blockchain.
Initially launched on Polygon, the platform has become one of the most active and accessible decentralised prediction markets worldwide.
Prediction Markets Go Mainstream With Big Tech Involvement
The Yahoo Finance integration comes less than a week after Google announced it would add prediction market data to Google Finance and Search, partnering with both Polymarket and its main competitor, Kalshi.
Kalshi, which focuses on event-based futures trading regulated in the United States, recently raised $300 million at a $5 billion valuation.
Earlier this year, it teamed up with Robinhood to allow retail investors to trade event contracts—ranging from sports outcomes to economic indicators—directly through the brokerage app.
While competition between Polymarket and Kalshi remains intense, both firms are helping to normalise prediction markets as a legitimate information and trading tool.
According to Dune Analytics, Polymarket and Kalshi generated around $1 billion and $1.3 billion in notional volume, respectively, over the past week.
Why Investors Are Paying Attention To Prediction Data
Prediction markets allow users to buy and sell shares tied to future outcomes—whether a government shutdown will end on a specific date or whether a candidate will win an election.
The prices act as probabilities, turning collective speculation into quantifiable forecasts.
These markets can sometimes offer more accurate insights than traditional polling or analyst forecasts, as they aggregate real-time data from participants putting their money on the line.
A recent example on Polymarket involved bets on when the U.S. government shutdown would end.
By mid-November, the market for “November 12” had attracted $1.48 million in bets, with odds showing a 64% chance of that date being correct.
The Growing Role Of Blockchain In Finance
For Yahoo Finance, the move to integrate prediction market data reflects the wider adoption of blockchain technologies within traditional financial services.
Prediction markets use decentralised ledgers to record trades transparently, removing intermediaries while providing insight into collective sentiment.
Analysts at Bernstein recently noted that prediction markets are evolving into “broader information hubs” covering not just politics or economics but also sports, culture, and business trends.
As more tech and finance firms explore the value of real-time, decentralised data, collaborations like Yahoo Finance’s exclusive deal with Polymarket highlight a growing belief that collective intelligence could reshape how investors assess risk and anticipate global events.
