DOT arbitrage explained
Right now Polkadot (DOT) trades on 11 venues we scan: 11 perpetual markets, 7 spot markets and 0 DEX pools. The lowest ask is on KuCoin perp at $1.13 and the highest bid on Bitget spot at $1.14.
The widest DOT perpetual spread is between OKX and Hyperliquid: long DOT on OKX at $1.13 and short on Hyperliquid at $1.13 for +0.03% gross, or -0.13% 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 +0.075% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best DOT route is to buy spot on Binance and short the perpetual on Hyperliquid: -0.10% gross, -0.30% net, with -0.030% a day of funding on the short leg.
Spot–spot DOT arbitrage (buy on Binance, withdraw, deposit and sell on Bitget) shows +0.05% 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 DOT 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.
