Internet reports that during the recent U.S. election, the trading volume of prediction market platform Polymarket surged. The transaction volume in October was close to US$2.5 billion and exceeded US$1.2 billion in November. Although a few "giant whale" users made a lot of money betting on Trump's victory, data shows that 86% of Polymarket users actually lost money. Of the approximately 371,000 user wallets, only 4004 achieved profits of more than $1000. Some users tried to obtain possible future token airdrops through high-frequency trading, but many users ended up losing money. In addition, Polymarket faces compliance investigations in France and may be banned.
