The price spread pays, funding is against you. Aster is 0.085% dearer against Polymarket Perps than usual: you sell high and buy low (spread +0.071% now, against its 7-day average of −0.015%): +$9 on $10k if it goes back. Holding the pair costs −$14 a day in funding at the current rate, which eats that in about 14 hours. At the pace of the last 6 days (−0.102% in total) that is about 4.7 days. The two prices were read 46 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 -0.102% in total (about -6.7% 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.
