GMTrade and MEXC both quote 23 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 XAU — long GMTrade / short MEXC at 10.7% net APR — but the median across all shared markets is 6.0%, 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 18 markets go long on GMTrade and 5 on MEXC. 12 markets clear 5% net APR, 4 clear 10%.

GMTrade pays funding every 1h on 48 markets; MEXC pays every 4h on 273 markets and every 8h on 126 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. GMTrade quotes 48 perpetual markets in total and MEXC quotes 400; the 23 they share are what this page ranks. Across its own book GMTrade runs a median funding rate of 0.1% and MEXC 7.4%, 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.
