The price spread pays, funding is against you. Bluefin is 0.075% dearer against Kalshi than usual: you sell high and buy low (spread +0.059% now, against its 7-day average of −0.016%): +$8 on $10k if it goes back. Holding the pair costs −$24 a day in funding at the current rate, which eats that in about 7 hours. At the pace of the last 7 days (−0.255% in total) that is about 2.1 days. The two prices were read 53 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 -0.255% in total (about -13.3% a year). A funding rate is set anew for every payment. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
