The legal position in Massachusetts
A Massachusetts judge ruled that Kalshi could not offer sports event contracts without complying with state gaming requirements, and initially ordered it to block users — before pausing that order while Kalshi appeals. Legal commentators often cite Massachusetts as the counterpoint to New Jersey: where New Jersey’s appeals court leaned toward the platform, a Massachusetts court leaned toward the state. Polymarket has historically blocked Massachusetts IP addresses.
Because the block is currently paused rather than lifted or enforced, availability is in flux. The underlying question — does federal derivatives law preempt Massachusetts gaming law? — is the same one heading toward higher courts nationally. See our legality overview.
Which platforms operate in Massachusetts
With a paused block hanging over the sports category, availability from Massachusetts is platform-specific and can shift with the appeal. Kalshi may or may not be offering sports contracts to Massachusetts users at any given moment; Polymarket has historically blocked the state.

Frequently asked questions
Can I use Kalshi in Massachusetts?
It is uncertain. A Massachusetts judge ordered Kalshi to block users over its sports contracts, then paused that order pending appeal. Whether Kalshi is serving Massachusetts users at any moment depends on the current state of that appeal — check its live eligibility page before funding.
Why is Massachusetts seen as the opposite of New Jersey?
In New Jersey, a federal appeals court let Kalshi keep operating while its case proceeds, signalling sympathy to the preemption argument. In Massachusetts, a state court ruled the other way on sports contracts. The contrast illustrates how inconsistently the same products are being treated across states.
