SOMI arbitrage explained
Right now Somnia (SOMI) trades on 8 venues we scan: 8 perpetual markets, 6 spot markets and 0 DEX pools. The lowest ask is on Bybit perp at $0.199 and the highest bid on Gate spot at $0.1995.
The widest SOMI perpetual spread is between Bybit and Gate: long SOMI on Bybit at $0.199 and short on Gate at $0.1993 for +0.18% gross, or +0.02% 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 SOMI route is to buy spot on Binance and short the perpetual on Gate: -0.10% gross, -0.30% net, with +0.030% a day of funding on the short leg.
Spot–spot SOMI arbitrage (buy on Binance, withdraw, deposit and sell on Gate) shows -0.02% 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 SOMI 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.
