Both sides work against this trade now: funding costs −$2 a day on $10k at the current rate, and Polymarket Perps is 0.119% cheaper against BloFin than usual: you would sell low and buy high (−$12 if the spread goes back to its 7-day average of −0.048%). Swap the legs. The two prices were read 105 seconds apart, so part of this spread may be the market moving, not a spread.
