MLB faces potential lockout in December 2026 over salary cap dispute, amid revenue decline.

A potential lockout in Major League Baseball (MLB) looms in December 2026, centering around a salary cap dispute. While MLB Commissioner Rob Manfred and some owners cite payroll disparity as an issue, the players' union strongly opposes a cap, leading to record player salaries. The league also faces a revenue decline from regional sports networks. The collective bargaining agreement expires in December 2026, and past negotiations have seen lockouts shift start dates to the offseason.
