A Polymarket trader known as Mayuravarma, who gained notoriety for turning $5,000 into $3.8 million through sports betting, has suffered significant losses. Within a week, his profits nearly evaporated due to unsuccessful bets on NHL and CFB matches. Following these losses, Mayuravarma's account was deleted on X, and as of November 26, his losses exceeded $885,000, leaving him with approximately $278,500. His initial strategy of betting on favorites shifted to high-risk all-in bets, which ultimately led to his downfall.
