Uniswap founder's interpretation of predicting market pricing differences: not due to user structure issues, or differences in event definitions and rules Odaily Planet Daily News: Uniswap founder Hayden Adams pointed out in an article on X platform that the predicted market price for Kalshi's "US acquisition of Greenland" is about 42%, while Polymarket's price is only 15% -23%. The significant price difference is not due to differences in user groups, but more from differences in specific betting targets themselves. If only the user structure is different, only one trader who can access both platforms at the same time can quickly smooth out the price difference through arbitrage. However, the actual situation may be that Polymarket's "probability of occurrence within 2026 (currently about 23%)" and Kalshi's "probability of occurrence throughout Trump's term (currently about 45%)" are not the same event. In addition, differences in problem description, settlement conditions, oracle design, and different risk pricing logics can all lead to different pricing.
