Both Kalshi and the state of Massachusetts faced probing questions from the Massachusetts Supreme Judicial Court in oral arguments Monday. But the nature of the case — in which Kalshi needs to win on two different points — means that the judges’ skepticism of arguments made by both parties may be favorable to the state.

Lawyers for Kalshi and Massachusetts made their arguments to the Massachusetts Supreme Judicial Court’s seven judges. Kalshi is appealing the Suffolk County Superior Court’s decision to grant an injunction that would ban the prediction market’s sports contracts from the state.

That injunction is not currently in effect while the appeal is being heard, but if it comes into force then Massachusetts would be the second state, after Nevada, to successfully ban Kalshi’s sports contracts.
