Polymarket to provide prediction data to Wall Street Journal, Barron's in Dow Jones deal

Polymarket, one of the leading prediction market platforms, has signed an exclusive deal with Dow Jones Media for its various properties.

Polymarket data will be displayed online and in print, and used in new features such as an earnings calendar — showing expected results for publicly traded companies, the firm said in a post on X. Dow Jones will publish the predictions data in outlets such as the Wall Street Journal, Barron's, and Investor’s Business Daily.

Polymarket and Kalshi have signed a plethora of media deals in recent months as prediction markets continue to gain a major foothold in the United States and abroad. Polymarket is the exclusive prediction market partner for Yahoo Finance, while Google Finance will roll out both Polymarket and Kalshi data in search results. Kalshi is CNN's official partner, integrating prediction market data into programming.

"What makes Polymarket so valuable is that they have data, collective intelligence, decentralized data from all around the world, wisdom of the crowd, essentially, that is able to give you much more accurate predictions on what's going to happen," Leo Chan, co-founder and CEO of the predictive intelligence startup Sportstensor, told The Block last month.

"This kind of information, this kind of data is extremely important and extremely valuable to people outside of the traders," Chan continued. "All these financial institutions that could use this kind of data see prediction markets as an infrastructure to collect this data."

Following various raises in 2025, Polymarket was most recently valued at $9 billion, while Kalshi's valuation was around $11 billion.

Earlier this week, Polymarket said it will offer a new suite of housing-related prediction markets via an integration with onchain real estate platform Parcl.

Of note, Polymarket confirmed in October that the company plans to launch a native POLY token and an accompanying airdrop.
