Two traders have filed a lawsuit against Polymarket over a dispute related to a market concerning the sale of Bitcoin. The plaintiffs held "yes" positions on whether the company would sell BTC by May 31.
Polymarket revealed the sale of 32 BTC scheduled for May 26-31, but subsequently closed the market as "no" following a decision by UMA, a system that adjudicates disputed outcomes on the platform. The plaintiffs accused Polymarket of changing the rules after the fact.
