Prediction market Polymarket has become popular during the 2024 U.S. election, with monthly trading volumes reaching nearly $2.5 billion in October and over $1.2 billion in November. However, a large majority of Polymarket users have lost money – 86% of accounts have a negative realized profit and loss margin, meaning users have either been wrong about their bets or sold at a loss.
The platform is currently being investigated in France, where one trader, Theo4, has profited $47 million from his bets.
