Funding pays, the price is against you. Kalshi is 0.044% cheaper against Hotstuff than usual: you would sell low and buy high (spread −0.044% now, against zero (this spread has no 7-day history yet)). If the spread goes back, that is −$4 on $10k: about 15 hours of funding at the current rate (+$7 a day).
