Massachusetts AG Expands Lawsuit Against Kalshi Over Sports Betting
Massachusetts' top prosecutor filed an amended complaint alleging Kalshi marketed sports prediction contracts to underage users via social media and college campuses.
The Massachusetts Attorney General has escalated its legal battle against prediction market platform Kalshi, filing an amended lawsuit following a court ruling that cleared the way for expanded allegations. The updated complaint, approved by a judge on Tuesday, sharpens the state's case by introducing new claims about how the company allegedly courted users younger than 21 — the legal minimum age for gambling in the state.
At the heart of the amended complaint is a pattern of marketing behavior that regulators say deliberately targeted younger audiences. Specifically, the AG's office alleges Kalshi ran promotional campaigns on social media platforms and conducted outreach on university campuses — channels that skew heavily toward the 18-to-22 demographic. That framing positions the case less as a technical regulatory dispute and more as a consumer protection matter with potential appeal to courts and public opinion alike.

The lawsuit sits within a broader national debate over how prediction markets should be classified and regulated. Kalshi, which gained federal approval to offer event contracts, has argued its products are distinct from traditional sports gambling and fall under federal commodity trading oversight rather than state gaming laws. Massachusetts is effectively challenging that jurisdictional argument by pursuing the company under its own consumer protection framework, a strategy that could influence how other states approach similar platforms.
If the Massachusetts case advances, it could set a meaningful precedent at a time when prediction markets are rapidly gaining mainstream traction. Regulators in multiple states are watching closely, and the outcome may determine whether platforms like Kalshi can operate freely under federal preemption or face a patchwork of state-level restrictions. The targeting-of-minors allegation, in particular, adds a layer of moral urgency that could accelerate legislative responses across the country.
