Both sides work against this trade now: funding costs −$9 a day on $10k at the current rate, and Polymarket Perps is 0.082% cheaper against Bybit than usual: you would sell low and buy high (−$8 if the spread goes back to its 7-day average of −0.073%). Swap the legs. Mind the row above: over the last 6 days funding on this pair paid +0.123%, so the current rate has only just turned against you. The two prices were read 47 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 6 days it paid 0.123% in total (about 8.0% a year). A funding rate is set anew for every payment. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
