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.

What is Mega Shark?
Some factions within the government, especially the Ministry of Finance, are resisting more drastic measures. The Ministry of Finance, responsible for regulating sports betting and online gaming, understands the sector’s importance to the economy. Finance Minister Dario Durigan’s difficulty lies in convincing Lula that a well-regulated activity is important for public finances. Lula has said, in line with critics of the sector, that if it were up to him, he would end betting in Brazil.
The president’s critical view of betting is on par with other candidates. Studies by the Workers’ Party (PT) indicate that three out of four Brazilians are against betting establishments. This is the president’s justification against the sector.
What the president didn’t address is the tax revenue from betting.
