Bybit and KuCoin both quote 164 of the same perpetual markets, so a delta-neutral position can be split across the two and collect the difference in their funding. The widest spread on a market with real depth is MUU — long Bybit / short KuCoin at 143.9% net APR — but the median across all shared markets is 26.6%, which is the number worth planning around.

The long leg is whichever venue prices funding lower for that market. It is a property of the MARKET, not of the exchange, and it flips as rates move: here 84 markets go long on Bybit and 80 on KuCoin. 143 markets clear 5% net APR, 121 clear 10%.

Bybit pays funding every 8h on 245 markets and every 4h on 201 markets; KuCoin pays every 4h on 233 markets and every 8h on 183 markets. The two clocks differ, so one leg settles while the other is still accruing: a position held for only a few hours can pay one side without ever collecting from the other. Bybit quotes 448 perpetual markets in total and KuCoin quotes 417; the 164 they share are what this page ranks. Across its own book Bybit runs a median funding rate of 10.6% and KuCoin 10.9%, so the edge here comes from individual markets rather than from a standing gap between the venues.

Net APR subtracts entry and exit fees, both legs' bid/ask spread and estimated slippage from the gross funding spread. The 7-day average is historical gross funding for the same pair: a current rate close to it suggests the spread has persisted, one far above it is usually a spike that will decay.
