Both sides work against this trade now: funding costs −$1 a day on $10k at the current rate, and MEXC is 0.044% cheaper against Polymarket Perps than usual: you would sell low and buy high (−$4 if the spread goes back to its 7-day average of +0.010%). Swap the legs. The two prices were read 49 seconds apart, so part of this spread may be the market moving, not a spread.
