KalshiRules
There are rumors of an expansion coming to Major League Baseball.
- When I check this market in the future, I want to know what year the expansion will happen in.
- The year that resolves Yes is the year where there are 31 or more teams, and the new team actually plays a game.
- It can officially resolve Yes once 31 teams have played a game in a season.
- Even if there are strong indications that this is going to happen, we should wait to resolve until it actually does.
- Resolves the named outcome if it doesn't happen before July 2031.
