Both sides work against this trade now: funding costs −$14 a day on $10k at the current rate, and Bybit is 0.087% cheaper against Polymarket Perps than usual: you would sell low and buy high (−$9 if the spread goes back to its 7-day average of +0.045%). Swap the legs. The two prices were read 47 seconds apart, so part of this spread may be the market moving, not a spread.
