[Polymarket whales made a fortune by betting on Trump, while 86% of users lost money] Golden Finance reported that during the recent US election, the trading volume of the prediction market platform Polymarket surged, with trading volume approaching $2.5 billion in October and exceeding $1.2 billion in November. Although a few "whale" users made a fortune by betting on Trump's victory, data shows that 86% of Polymarket users actually lost money. Among the approximately 371,000 user wallets, only 4,004 realized a profit of more than $1,000. Some users tried to obtain possible future token airdrops through high-frequency trading, but many users ended up losing money. In addition, Polymarket faces a compliance investigation in France and may be banned.
