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.
The news comes as prediction market operators continue to form alliances with major media outlets. These deals allow news outlets to embed event contract data into their reporting and offer prediction platforms more visibility to investors and news audiences.

Funds held in customer accounts also declined sharply. Operators held £886.6 million ($1.19 billion), down 13.9% from the same point a year earlier.
Retail betting diverged significantly from the wider market, with non-remote betting GGY falling 3.3% to £2.4 billion ($3.2 billion). The number of betting shops dropped for a 12th consecutive reporting period to 5,617 premises—a 3.6% annual decline (down 208 shops from March 2025).
Other retail sectors performed better. Bingo GGY increased 8.2% to £703.8 million ($941.8 million), while arcade GGY rose 10.7% to £800.1 million ($1.07 billion).

One of its investigations concerns a specific globally renowned brand. Madsen says an initial scan identified around 1,600 domains, followed by another roughly 4,500 associated with this operator. That puts the number identified so far at around 6,000, although he believes the actual figure is considerably higher. “I think what we’ve found so far is only a small part of the overall picture,” he says. “I’m almost certain the real number is at least twice as high.”
Euromat’s report has suggested that a core group of 25 offshore operators are generating up to 64% of European traffic to the black market.
Madsen says investigators can also examine how sites appear from different jurisdictions. If a site is presented in a country’s local language, for example, that can indicate that the market is being targeted. The next question is whether the operator has the necessary licence.
