Together, before fees—needs both histories

The price spread pays, funding is against you. Kalshi is 0.296% dearer against Aftermath Perps than usual: you sell high and buy low (spread +0.296% now, against zero (this spread has no 7-day history yet)): +$30 on $10k if it goes back. Holding the pair costs −$12 a day in funding at the current rate, which eats that in about 2.5 days.
