Kalshi
Best overall
Kalshi is the closest like-for-like swap: a CFTC-regulated exchange with similar sports, politics and crypto markets and far more volume. Its taker fee is almost identical at up to 1.75¢ per contract, most maker orders are free rather than rebated, and it accepts PayPal, Venmo and crypto and pays a 3.25% variable APY on balances of $250 or more. Court orders block its sports contracts in Nevada, Michigan and Washington, though.
