The price spread pays, funding is against you. Polymarket Perps is 0.040% dearer against BloFin than usual: you sell high and buy low (spread −0.008% now, against its 7-day average of −0.048%): +$4 on $10k if it goes back. Holding the pair costs −$22 a day in funding at the current rate, which eats that in about 4 hours. At the pace of the last 7 days (−0.072% in total) that is about 3.9 days. The two prices were read 45 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 -0.072% in total (about -3.8% 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.
