Both sides work against this trade now: funding costs −$21 a day on $10k at the current rate, and Bitget is 0.030% cheaper against GRVT than usual: you would sell low and buy high (−$3 if the spread goes back to its 7-day average of +0.008%). Swap the legs. The two prices were read 83 seconds apart, so part of this spread may be the market moving, not a spread.

The current funding rate is far above what this pair has been paying: over the last 7 days it paid 0.016% in total (about 0.9% a year). A funding rate is set anew for every payment; at this rate the next one is about −$7.11 per $10,000. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
