KSM arbitrage explained
Right now Kusama (KSM) trades on 8 venues we scan: 8 perpetual markets, 7 spot markets and 0 DEX pools. The lowest ask is on Variational perp at $4.82 and the highest bid on Bitget spot at $4.83.
The widest KSM perpetual spread is between Variational and Binance: long KSM on Variational at $4.82 and short on Binance at $4.82 for +0.13% gross, or -0.03% 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 +0.159% per day, which the position collects while it is open.
For a spot–perpetual (cash-and-carry) trade, the best KSM route is to buy spot on Gate and short the perpetual on Binance: 0.00% gross, -0.20% net, with +0.029% a day of funding on the short leg.
Spot–spot KSM arbitrage (buy on Gate, withdraw, deposit and sell on Bitget) shows +0.23% 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 KSM 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.
