Massachusetts Justices Scrutinise Kalshi’s Sports Betting Defence

Massachusetts’ Supreme Judicial Court heard Kalshi’s appeal against an injunction blocking its sports-related contracts. According to the state, the company is offering unlicensed sports betting. Kalshi argues its products fall under the CFTC’s exclusive federal jurisdiction.

Court Questions Swap Defence

Chief Justice Scott Kafker questioned Kalshi’s position during oral arguments, asking whether using the site to bet on a Jayson Tatum three-point shot would still amount to gambling. “This does seem to have a major aspect of sports gambling to it,” Kafker said.

Justice Gabrielle Wolohojian also challenged Kalshi’s framing. “If we just zoomed up one level,” she told Kalshi attorney Grant Mainland, the swaps “would not be conceptually incompatible with what we historically understand to be a bet or a wager.”

Kalshi argues its yes-or-no event contracts are swaps under the Commodity Exchange Act, as expanded by Dodd-Frank in 2010. The company also claims state gambling laws are preempted because the CFTC has exclusive authority over federally regulated derivatives markets.

Massachusetts argues Kalshi’s sports products mirror sportsbook mechanics, including point spreads, over/unders, proposition bets and parlays. State solicitor Gerard Cedrone also said peer-to-peer pricing does not remove a product from gambling law, citing horse racing as a betting model where odds are not set by the operator.

The case has drawn national attention. According to the reporting provided, nearly 40 state attorneys general have backed Massachusetts. Prediction market disputes are also moving through courts in Nevada, New Jersey and other states.

Campbell’s office says the state needs authority over sports-related event contracts because Kalshi does not apply the same consumer protections as licensed sportsbooks, including age limits and responsible gambling controls.

💡 TGJ Take

Kalshi’s strongest business problem is not one state injunction. It is the chance that courts treat sports-event contracts as betting products wherever consumers use them like bets. If that happens, prediction markets lose their main regulatory advantage over licensed sportsbooks. Operators with existing licences, tax systems and responsible gambling controls would be better placed than exchange-style challengers trying to retrofit compliance after the fact.
