Both sides work against this trade now: funding costs −$3 a day on $10k at the current rate, and Polymarket Perps is 0.150% cheaper against MEXC than usual: you would sell low and buy high (−$15 if the spread goes back to its 7-day average of −0.004%). Swap the legs. The two prices were read 49 seconds apart, so part of this spread may be the market moving, not a spread.
