Researchers Find Rigged Bitcoin Bets on Polymarket

A group of traders reportedly pocketed 8.2 million dollars from Polymarket by gaming the system. Researchers from Stanford University and Singapore Management University discovered that these traders influenced the spot price of Bitcoin on Binance during the final ten seconds of five minute betting contracts. This activity allowed them to profit at the expense of other participants.

The study points to a clear pattern of settlement manipulation within these fast paced betting products. By pushing the price at the last possible moment, the traders ensured their positions settled in their favor. This incident highlights the vulnerabilities present when prediction markets rely on spot price data from a single exchange.

Market observers are now questioning the safety of these ultra short duration betting products. While Polymarket remains a popular platform, this research suggests that high frequency traders have found ways to tilt the odds. Traders should remain cautious when engaging with platforms that settle based on brief windows of price activity.

Looking ahead, the industry will likely watch for how prediction platforms adjust their settlement procedures. Protecting against such price influence is essential for maintaining trust. Future updates to betting protocols may involve using broader price feeds to prevent similar manipulation.
