(Bloomberg) -- Yahoo Finance has ended a partnership with Polymarket in which the financial news platform used Polymarket data to create a prediction market hub on its website.

The companies joined forces last November, with Polymarket saying in a social media post at the time that it had become Yahoo Finance's exclusive prediction market partner. The agreement included a hub to display probability data for "key economic, government, & market outcomes."
The hub was taken down in April, and the overall agreement has concluded.
"We had a previous partnership with Polymarket to display relevant prediction market data across Yahoo Finance," a Yahoo spokesperson said in a statement. "That specific agreement ended, but Polymarket continues to be an advertising partner across Yahoo and we're open to similar types of partnerships."
Polymarket declined to comment.
Yahoo was one of several media companies that has cut deals with prediction markets to use the forecasts on the platforms in news broadcasts, websites and print publications.
Polymarket struck a partnership in January to feed its prediction data to News Corp.'s Dow Jones, the parent of the Wall Street Journal and other publications. Kalshi, a Polymarket rival, has announced deals with Warner Bros. Discovery Inc.'s CNN, Versant Media Group's CNBC and Fox Corp. (Bloomberg LP, the parent of Bloomberg News, has no such partnership, but it does provide Polymarket and Kalshi data to clients as part of its broader data offering.)
Consumers can use prediction markets to place wagers on sports, election outcomes and financial markets, as well as other events. The odds on the platform reflect the balance of trading on the platform.
While both Kalshi and Polymarket have argued that prediction markets can help enhance journalism, critics have questioned whether their data accurately captures public sentiment. Cash-strapped media organizations have been criticized for looking to these partnerships as a way to drum up new revenue streams.
The platforms are also embroiled in several other controversies, with many state regulators arguing in court that they violate local gambling laws, and prosecutors pointing to several alleged cases of insider trading. The companies have said that they monitor for illegal trading and should be governed as derivatives exchanges by the Commodity Futures Trading Commission.
