The widest F perpetual spread is between Bybit and Bitget: long F on Bybit at $0.003238 and short on Bitget at $0.003248 for +0.31% gross, or +0.15% 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 0.000% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best F route is to buy spot on Gate and short the perpetual on Bitget: +0.19% gross, -0.01% net, with +0.030% a day of funding on the short leg.
Spot–spot F arbitrage (buy on Gate, withdraw, deposit and sell on Bitget) shows +0.15% 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 F 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.
