Phantom has disclosed the fee structure for its newly launched US prediction markets, charging $0.02 per contract split between Phantom and Kalshi, plus a network fee. The feature integrates Kalshi's regulated event trading platform directly within the wallet interface. Trades on Phantom's prediction markets are funded through Kalshi rather than the user's crypto balance. Notably, Kalshi account balances do not appear in the Phantom wallet UI, requiring users to manage funds separately on the Kalshi platform.
