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.
Prediction markets have become more and more intertwined with sports and entertainment businesses. Polymarket has agreements with Major League Baseball and Sportsradar. Sportsradar provides data and services for more than 20 sports leagues and competitions.
The company has also pursued partnerships outside the normal financial media. Its deals include relationships with major sports organizations and entertainment properties, signaling efforts to integrate prediction markets into mainstream content and information services.

In July the Commission said its investigation had discovered the supplier had failed to maintain adequate anti-money laundering and customer due diligence controls in the UK.
