A Stanford study found that Polymarket's five-minute Bitcoin prediction markets create incentives for spot price manipulation around settlement. Researchers suggest longer settlement windows could prevent this issue, promoting fairer outcomes for traders.
Researchers at Stanford have uncovered a potential flaw in short-term Bitcoin prediction markets. They found that platforms like Polymarket, which offer markets settling in just five minutes, create incentives for people to manipulate Bitcoin's spot price right before the contract ends. This manipulation could unfairly affect the outcome of bets. To solve this, the study suggests that these markets should have longer settlement periods. A longer window would reduce the ability for individuals to artificially sway prices, making the markets more secure and trustworthy for everyone participating in Web3.
