Both sides work for this trade now. Funding pays +$6 a day on $10k at the current rate, and Kalshi is 0.026% dearer against Aster than usual: you sell high and buy low: +$3 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.

The current funding rate is far above what this pair has been paying: over the last 7 days it paid 0.017% in total (about 0.9% a year). A funding rate is set anew for every payment; at this rate the next one is about +$2.06 per $10,000. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
