On January 20, a Massachusetts judge granted a preliminary injunction against Kalshi’s offering and acceptance of sports event contracts in the state of Massachussetts.

This market will resolve to “Yes” if Kalshi stops offering sports event contracts to users in the state of Massachusetts by January 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.

Stops offering sports event contracts refers to any halt—whether permanent or temporary—in Kalshi’s listing, offering, acceptance, or facilitation of sports event contracts for users in Massachusetts that is intentional and not simply a result of routine operations. Delays caused by gaps between sporting events, technical problems, or other unintentional factors will not qualify.

An official announcement from Kalshi that it will stop offering sports event contracts in Massachusetts within this market's timeframe will suffice to resolve this market, regardless of when or if the announced stop takes effect.

A stop limited to a specific subset of sports event contracts (e.g. prop bets or parlays), that does not include contracts on the win/lose outcomes of sporting events, will not qualify.

Kalshi allowing users to close, redeem, or hold existing positions during an otherwise qualifying stop will not disqualify that stop from counting.

The primary sources of resolution for this market will be official information from Kalshi; however, a consensus of credible reporting will also be used.
