The price spread pays, funding is against you. edgeX is 0.551% dearer against Polymarket Perps than usual: you sell high and buy low (spread +0.686% now, against its 7-day average of +0.135%): +$55 on $10k if it goes back. Holding the pair costs −$4 a day in funding at the current rate, which eats that in about 13 days. At the pace of the last 7 days (−0.139% in total) that is about 28 days. The two prices were read 64 seconds apart, so part of this spread may be the market moving, not a spread.
