Bitget and Ostium both quote 14 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 MU — long Ostium / short Bitget at 41.1% net APR — but the median across all shared markets is 9.2%, 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 1 markets go long on Bitget and 13 on Ostium. 9 markets clear 5% net APR, 7 clear 10%.

Bitget pays funding every 4h on 253 markets and every 8h on 239 markets; Ostium pays every 1h on 34 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. Bitget quotes 495 perpetual markets in total and Ostium quotes 34; the 14 they share are what this page ranks. Across its own book Bitget runs a median funding rate of 10.1% and Ostium 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.
