Both sides work for this trade now. Funding pays +$5 a day on $10k at the current rate, and Kalshi is 0.158% dearer against Aster than usual: you sell high and buy low: +$16 more if the spread goes back to its 7-day average of −0.004%. The two prices were read 51 seconds apart, so part of this spread may be the market moving, not a spread.
