The widest GMT perpetual spread is between KuCoin and Variational: long GMT on KuCoin at $0.00818 and short on Variational at $0.008201 for +0.26% gross, or +0.10% 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 -0.039% per day, which the position pays while it is open.
For a spot–perpetual (cash-and-carry) trade, the best GMT route is to buy spot on Binance and short the perpetual on Variational: +0.01% gross, -0.19% net, with -0.009% a day of funding on the short leg.
Spot–spot GMT arbitrage (buy on Binance, withdraw, deposit and sell on Gate) shows +0.38% 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 GMT 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.
