What is Treasure Trawler?

Yahoo Finance has soured on prediction market Polymarket, closing a deal between the financial news platform and the event contract operator in less than a year after it began. 

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.

Various MPs voiced concerns about the risk of privacy violations in accessing this data, and the potential social stigma around the information being shared.

Entain said it had requested meetings with government officials to present its concerns directly and facilitate engagement between ministers and frontline shop staff before final budget decisions are made.
