An anonymous trader won over $400,000 on the prediction market platform Polymarket by betting on the downfall of former Venezuelan President Nicolas Maduro. The large payout, made shortly before a raid led to Maduro's capture, has sparked suspicions of insider trading due to the timing. However, others suggest prior speculation or the inherent risks of such markets could explain the outcome. Prediction markets, which allow wagers on various future events, are facing increased scrutiny regarding transparency and regulation.
