Polymarket has expanded its offerings for users in the US by adding new binary trading options focused on the price movements of several digital assets. These “up/down” markets for Bitcoin, Ethereum, Solana, and XRP allow participants to bet on whether an asset’s price will be higher or lower at the end of a 5 minute window, with winning contracts paying out $1.
The new product places the platform in direct competition with Kalshi, which offers similar crypto price predictions that settle over 15 minute intervals. Polymarket will utilize index averages to determine the settlement of the contracts, and any tied results will be settled in favor of the “Up” side.
