Both sides work against this trade now: funding costs −$5 a day on $10k at the current rate, and KuCoin is 0.073% cheaper against Polymarket Perps than usual: you would sell low and buy high (−$7 if the spread goes back to its 7-day average of +0.022%). Swap the legs. The two prices were read 49 seconds apart, so part of this spread may be the market moving, not a spread.
