About Iron Bank 2

Yahoo Finance has ended its dedicated prediction market integration with Polymarket, cutting short a high-profile partnership less than a year after launch.

The investing and news site announced last week that it halted an arrangement in which it used Polymarket prediction market data for a dedicated hub on the website.

That relationship ended in April, just six months after it started. Yahoo Finance confirmed the end of that agreement to Bloomberg but noted that Polymarket remains an advertising partner.

Its findings contained an all-too-familiar combination of ineffective systems, delayed interventions and inadequate source-of-funds controls. One customer placed approximately 4,800 bets in one day and 7,000 the next without being flagged. Another, whose payslips showed monthly earnings of about £2,000, deposited and lost £9,000 in four days.

“What is striking here is the level of activity that apparently failed to trigger effective intervention,” Williams says. “These were obvious indicators requiring further scrutiny, and it is difficult to understand why they did not result in more effective intervention.”

He adds that the recurring weakness is often not an absence of policies but a failure to ensure “technology, algorithms and operational processes actually work in practice”. Some of the QuinnBet issues followed a platform migration, underlining the need to retest controls whenever systems change.

“We had various iterations of the drafts internally probably going back at least a decade, and just never made it to the finish line for various reasons,” he explained.

The board is hoping that the proposal drafts or more or less finalised, though there will likely be input from stakeholders during the comment period and at the hearing. One group that typically weighs in on such matters, the Association of Gaming Equipment Manufacturers, did not respond to a request for comment by Friday’s deadline for publication. Depending on the amount of feedback or potential objections from the Nevada Gaming Commission, the new standards could be adopted and published by year’s end.

Overall, it’s been a busy stretch for the board since the start of 2025. In that time the regulator has issued five multimillion-dollar anti-money laundering fines to entities on the Las Vegas Strip, an unprecedented run of sanctions for America’s gambling capital.
