I think the case is pretty clear regardless: gambling is supposed to be a state-regulated activity, and Kalshi is gambling but is regulated by the CFTC at the federal level. So I think the argument is "we want to be the ones to regulate sports gambling in our state," whoch is independent of whether or not it's currently legal in the state.

Or maybe I'm wrong, and "we don't want sports gambling" is different legally from "we want to be the regulator of gambling." But it seems like they're just variations of the same question, which is: do states have the power to regulate this?
