Aster and KuCoin both quote 94 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 DOOD — long KuCoin / short Aster at 134.3% net APR — but the median across all shared markets is 18.2%, 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 40 markets go long on Aster and 54 on KuCoin. 75 markets clear 5% net APR, 66 clear 10%.

Aster pays funding every 4h on 140 markets and every 8h on 96 markets; KuCoin pays every 4h on 233 markets and every 8h on 183 markets. Both sides settle on the same clock, so a position opened here collects or pays on both legs at once — the spread you see is the spread you get. Aster quotes 246 perpetual markets in total and KuCoin quotes 417; the 94 they share are what this page ranks. Across its own book Aster runs a median funding rate of 10.9% 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.
