Polymarket’s Trump/Ukraine mineral deal bet sparked a backlash as a whale-controlled vote settled it incorrectly, raising concerns over manipulation and governance risks.
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.
