What is Sizzling Diamonds?
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.
About Sizzling Diamonds
The conflict stems back to January 2025, when the outgoing Biden administration initially determined that the Vallejo parcel was eligible for gaming.
Interior temporarily rescinded that determination just two months later after newly appointed Secretary Doug Burgum raised concerns over whether the tribe’s historical connection to the land had been thoroughly evaluated.
Scotts Valley filed suit in response. In October 2025, Judge McFadden ruled that Interior had violated the tribe’s due process rights by rescinding the approval without giving prior notice or an opportunity to respond.

But Playtech has claimed that the Spectrum report, which is now publicly available, was unable “to confirm or refute” some of Black Cube’s claims, “as Evolution failed to provide Spectrum with significant information it had requested”.
Evolution declined to provide a comment on the update.
Notably, Spectrum said within its report that it did not believe Evolution had engaged in any illegal practices. It also refuted allegations concerning cash payments and the use of Evolution’s games in sanctioned countries.
