Resolution criteria

This market resolves to YES if Major League Baseball (MLB) and the MLB Players Association (MLBPA) ratify a new Collective Bargaining Agreement (CBA) or modify the existing agreement to implement a mandatory salary cap (a team payroll ceiling) or a mandatory salary floor (a team payroll minimum) for any MLB season starting prior to January 1, 2030.

Otherwise, this market resolves to NO.

Definitions and Details:

• Salary Cap: Must function as a maximum limit on team payrolls. A "hard cap" (prohibiting spending above a certain limit) or a cap tied strictly to a percentage of revenues qualifies. A continuation or adjustment of the existing Competitive Balance Tax (CBT) system does not qualify as a salary cap unless it is officially structured or formally referred to as a "salary cap" in the final CBA agreement.

• Salary Floor: Must function as a mandatory minimum payroll that teams must spend on player salaries. A "soft floor" carrying financial penalties for non-compliance (such as a "competitive integrity tax") will qualify if it is officially implemented to enforce minimum payroll levels.

• Timing: The cap or floor must be active for a season that begins before January 1, 2030. If a CBA is signed before 2030 but the cap/floor is not scheduled to take effect until the 2030 season or later, this market resolves to NO.

• Source of Truth: Official CBA documents or joint press releases published by MLB and the MLBPA.

Background

The five-year CBA signed in 2022 is scheduled to expire on December 1, 2026. In May 2026, MLB owners made an initial economic proposal for the next CBA that included a hard salary cap of $245.3 million and a salary floor of $171.2 million. The MLBPA has historically resisted any form of a hard salary cap, setting the stage for highly contentious negotiations and a potential work stoppage ahead of the 2027 season.
