The price spread pays, funding is against you. Polymarket Perps is 0.691% dearer against OKX than usual: you sell high and buy low (spread +0.691% now, against zero (this spread has no 7-day history yet)): +$69 on $10k if it goes back. Holding the pair costs −$29 a day in funding at the current rate, which eats that in about 2.4 days. The two prices were read 47 seconds apart, so part of this spread may be the market moving, not a spread.
