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.

It had sent over 217,000 marketing emails and SMS messages within a 16-day window to customers who had explicitly unsubscribed. ACMA regarded the volume and timing of these messages as significant enough to warrant enforcement action. 

In response to the penalties, Dabble Sports has agreed to a two-year court-enforceable undertaking. It has obliged the company to commission an independent review of its compliance systems. Dabble must develop a board-approved plan to implement these changes with appropriate resources.

An ACMA spokesperson reiterated: “BetStop is an important consumer protection measure, but it only works if wagering companies follow the rules.” 

What is Gemstone?

The Monday Powerball drawing had players competing for a jackpot of $314 million with a cash value of $133.8 million. In order to win, players had to correctly match all six winning numbers. The white winning numbers for the September 21 drawing were 2, 7, 9, 17, and 58. The red Powerball, on the other hand, was 20, while the Power Play multiplier stood at 2x.

Unfortunately, a jackpot win did not occur, although the game continued to award smaller prizes to players across the US and UK. As mentioned, a second Match 5 win happened in the UK, where a lucky player succeeded in matching all five winning numbers to redeem a $1 million payout. The drawing did not have a Match 5 + Power Play win of $2 million.

At the same time, 14 players matched four white numbers plus the Powerball, which netted them tier three prizes. As a result, 8 players won $50,000 each, while the remaining 6 took home $100,000 each instead, thanks to Power Play.
