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.

“If we just sold the data to Kalshi in order to list the markets but no one was coming in and placing liquidity, there’s no point in them listing the markets,” Monk said. “We also need to supply the data to the market makers to inform their models.”
Catalist initially received a list of fewer than 10 potential market makers from Kalshi. It has since completed agreements with close to 20 and is engaging with approximately another 20.
