KuCoin and Risex both quote 17 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 BZ — long KuCoin / short Risex at 37.6% net APR — but the median across all shared markets is 9.9%, 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 9 markets go long on KuCoin and 8 on Risex. 14 markets clear 5% net APR, 8 clear 10%.

KuCoin pays funding every 4h on 233 markets and every 8h on 183 markets; Risex pays every 1h on 43 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. KuCoin quotes 417 perpetual markets in total and Risex quotes 43; the 17 they share are what this page ranks. Across its own book KuCoin runs a median funding rate of 10.9% and Risex 0.0% — the two sit on opposite sides of zero, which is why this combination throws up spreads at all.

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.
