Study finds $8.2M in suspected price manipulation in Polymarket Bitcoin prediction markets.

Researchers from Stanford and Singapore Management University found suspicious trading on Binance that influenced Bitcoin prices just before Polymarket contract settlements. This activity, concentrated in low liquidity periods, likely generated $8.2 million in profits for some traders at the expense of retail participants. Polymarket plans to extend settlement timeframes and use multiple price feeds to reduce manipulation risks. The findings raise concerns as traditional exchanges like Cboe and Nasdaq enter prediction markets with more regulated structures.
