How this compares to Wisconsin sports betting

Where a state allows sports betting, sportsbooks are licensed and taxed by that state; an event contract on a federal exchange is neither, which is the whole dispute. The Wisconsin action concerns Polymarket's sports contracts. Whether a state may enforce at all is the question the federal appeals courts have split on. Wisconsin is outside the Third, Sixth and Ninth Circuits, the three appeals courts that have ruled. The question is unresolved there. Litigation tracker
