What is Guss Gold Minecart Mayhem?

In January, Polymarket and Dow Jones announced an agreement that paved the way for event contract data to appear on various Dow Jones sites, including The Wall Street Journal. Dow Jones also owns Barron’s, Investor’s Business Daily and MarketWatch, among other media properties.

Polymarket also has marketing deals with Major League Baseball (MLB), Major League Soccer (MLS), the NHL and UFC.

The two companies began collaborating in November 2025. As part of the deal, Polymarket provided data for a dedicated prediction market section on Yahoo Finance. The feature provided market-based probabilities of economic, political, and financial developments alongside Yahoo Finance content. 

The Yahoo Finance prediction market section was taken out in April. The companies have now confirmed that the larger deal is also off, as reported by Bloomberg. 

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.

Examples included phrases like “online casino zonder Cruks” (online casino without CRUKS, the Dutch self-exclusion registry for problem gamblers) and “beste online casino buitenland” (best online casino abroad).
