Binance and Vest both quote 13 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 ZK — long Vest / short Binance at 37.2% net APR — but the median across all shared markets is 11.1%, 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 Binance and 4 on Vest. 12 markets clear 5% net APR, 7 clear 10%.

Binance pays funding every 4h on 234 markets and every 8h on 85 markets; Vest pays every 1h on 63 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. Binance quotes 320 perpetual markets in total and Vest quotes 63; the 13 they share are what this page ranks. Across its own book Binance runs a median funding rate of 8.3% and Vest 5.0%, 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.
