An anonymous trader made more than $400,000 on Polymarket after betting that Venezuela’s President Nicolas Maduro would be removed from power. The wager was placed when the odds stood at just 5 to 7 percent, hours before US forces captured Maduro in a highly classified operation in Caracas. The account was created days earlier and focused solely on Venezuela-related outcomes. The timing has raised scrutiny around prediction markets, which allow bets on political and global events and operate under looser oversight than stock markets. US lawmakers are now proposing restrictions on officials trading on such platforms.
