How this compares to state 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. In Missouri, every action on record concerns sports contracts. Whether a state may act at all is the question the appeals courts have split on. Missouri is outside the Third, Sixth and Ninth Circuits, the three appeals courts that have ruled. The question is unresolved there. The federal picture
