Digital Assets Polymarket faces scrutiny over $7M Ukraine mineral deal bet

Polymarket, the world’s largest decentralized prediction market, is under fire after a controversial outcome raised concerns over potential governance manipulation in a high-stakes political bet.
A betting market on the platform asked whether US President Donald Trump would accept a rare earth mineral deal with Ukraine before April. Despite no such event occurring, the market was settled as “Yes,” triggering a backlash from users and industry observers.

This may point to a “governance attack” in which a whale from the UMA Protocol “used his voting power to manipulate the oracle, allowing the market to settle false results and successfully profit,” according to crypto threat researcher Vladimir S.

“The tycoon cast 5 million tokens through three accounts, accounting for 25% of the total votes. Polymarket is committed to preventing this from happening again,” he wrote in a March 26 X post.



Polymarket employs UMA Protocol’s blockchain oracles for external data to settle market outcomes and verify real-world events.

Polymarket data shows the market amassed more than $7 million in trading volume before settling on March 25.



Still, not everyone agrees that it was a coordinated attack. A pseudonymous Polymarket user, Tenadome, argued that the outcome was the result of negligence.

“There is no ‘tycoon’ who ‘manipulated the oracle,’ Tenadome wrote in a March 26 X post, adding:

“The voters that decided this outcome are the same UMA whales who vote in every dispute, who (1) are largely affiliated with/on the UMA team and (2) do not trade on Polymarket, and they just chose to ignore the clarification to get their rewards and avoid being slashed.”

Despite user frustration, Polymarket moderators said no refunds would be issued.

“We are aware of the situation regarding the Ukraine Rare Earth Market. This market resolved against the expectations of our users and our clarification,” Polymarket moderator Tanner said, adding:

“Unfortunately, because this wasn’t a market failure, we are not able to issue refunds.”
