The widest PROM perpetual spread is between Gate and Bitget: long PROM on Gate at $5.73 and short on Bitget at $5.76 for +0.56% gross, or +0.40% after the 0.16% two-leg fee model. No transfer is needed: both positions stay on their exchanges until the prices converge. The funding difference on this pair is +0.158% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best PROM route is to buy spot on Gate and short the perpetual on Bitget: +0.34% gross, +0.14% net, with +0.030% a day of funding on the short leg.
Spot–spot PROM arbitrage (buy on Gate, withdraw, deposit and sell on KuCoin) shows +0.32% gross right now. It only works if withdrawals on the buying exchange and deposits on the selling exchange are open, so check the D/W dots before moving coins.
Small PROM gaps usually disappear after fees, slippage and funding. Look at the Net column, the executable Depth and the spread history before trading: a gap that has been open for days is a different trade from a one-minute spike.
