Aster and MEXC both quote 108 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 BTW — long Aster / short MEXC at 50.0% net APR — but the median across all shared markets is 10.2%, 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 31 markets go long on Aster and 77 on MEXC. 78 markets clear 5% net APR, 54 clear 10%.

Aster pays funding every 4h on 136 markets and every 8h on 95 markets; MEXC pays every 4h on 267 markets and every 8h on 124 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 242 perpetual markets in total and MEXC quotes 392; the 108 they share are what this page ranks. Across its own book Aster runs a median funding rate of 10.9% and MEXC 7.5%, 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.
