Yahoo said Polymarket is still an advertising partner and suggested the two could collaborate on other projects in the future. Polymarket has not provided any public explanation for the end of the data partnership. 

The news comes as prediction market operators continue to form alliances with major media outlets. These deals allow news outlets to embed event contract data into their reporting and offer prediction platforms more visibility to investors and news audiences. 

Polymarket has developed its media presence elsewhere. In January, it signed a deal with Dow Jones to provide its prediction market data to several of the publisher’s consumer platforms. The deal covers publications including The Wall Street Journal, Barron’s, MarketWatch and Investor’s Business Daily.

“The new hub will display probability data from Polymarket for key economic, government, & market outcomes,” said Polymarket in a post on X last November. “Each probability view will be paired with related news, quotes, & analysis from Yahoo Finance + its partners. By combining trusted data with in-depth analysis, the hub will empower investors to make smarter, more strategic prediction market investments.”

Yahoo—which is 90% owned by private equity giant Apollo Global Management, the firm that acquired operating control of The Venetian in Las Vegas—did not elaborate on why the Polymarket integration ended.

Yahoo Finance is one of the most visited financial news websites in the world, implying it’s a blow to Polymarket that its prediction market hub was pulled, but the operator has other prominent financial media deals.
