The price spread pays, funding is against you. BingX is 0.192% dearer against Polymarket Perps than usual: you sell high and buy low (spread +0.150% now, against its 7-day average of −0.042%): +$19 on $10k if it goes back. Holding the pair costs −$1 a day in funding at the current rate, which eats that in about 29 days. At the pace of the last 7 days (−0.374% in total) that is about 3.6 days. The two prices were read 51 seconds apart, so part of this spread may be the market moving, not a spread.
