Resolution rules

Each outcome is a separate contract with its own rules. The rules for Las Vegas:

If Pro Basketball officially announces the award of an expansion team franchise to Las Vegas before Jan 1, 2028, then the market resolves to Yes. The league must officially announce that the city has been awarded an expansion franchise. This requires formal approval by the league's Board of Governors or equivalent governing body specifically naming the city. Preliminary discussions, stadium approvals without franchise awards, feasibility studies, or being named as a potential market do not qualify. Franchise relocations only count if specifically designated as "expansion" by the league. The announcement must come after market issuance. Even if the team won't begin play until after the target date, the market resolves Yes upon the official award announcement. Awards to nearby cities in the same region only count if they specifically include the named city or its metropolitan area. Kalshi is not affiliated, associated, authorized, endorsed by, or in any way officially connected with the Governing League.
