The price spread pays, funding is against you. Polymarket Perps is 0.020% dearer against Reya than usual: you sell high and buy low (spread +0.060% now, against its 7-day average of +0.040%): +$2 on $10k if it goes back. Holding the pair costs −$4 a day in funding at the current rate, which eats that in about 13 hours. At the pace of the last 3 days (−0.038% in total) that is about 43 hours.
