Major League Baseball’s ongoing negotiation over a proposed salary cap system has sparked significant disagreement between team owners and the players’ union, centered primarily on the interpretation and calculation of a so-called “50-50” revenue split. Team owners have put forward a plan that would establish a formal salary cap tied to a defined share of baseball revenues, but the players’ union disputes both the fairness and transparency of the league’s proposal.

On May 28, Major League Baseball (MLB) presented a detailed proposal outlining a revenue-sharing framework under which players and clubs would each receive an equal share — 50 percent — of what the league defines as “baseball revenue” (B.R.). According to Glen Caplin, an MLB representative, the plan “levels the playing field while sharing baseball revenue with the players 50-50,” linking player compensation more directly to league income as it grows.

However, the players’ union challenges MLB’s characterization of the split as equitable. Bruce Meyer, the interim head of the union, argued that players already receive well over half of the annual $12 billion revenue generated by the industry, and that the league’s claim of an equal share is “misleading propaganda.” A core point of contention lies in MLB’s method of calculating baseball revenue, which includes numerous deductions before the split is applied.

The league proposal permits deductions of up to 17 percent of local revenues and 22 percent of national revenues annually, alongside uncapped expenses for areas such as ballpark construction and renovation, broadcast costs for select seasons, and new ventures. Meyer described these “skimmings” from the top as a way to reduce the actual pool of revenue shared with players. Furthermore, revenue generated from franchise value growth, expansion fees, and various ancillary business operations, including real estate developments outside stadiums, would largely be excluded from the players’ share.

MLB’s revenue definition encompasses traditional income streams such as ticket sales, merchandise, broadcasts, concessions, suite sales, and most stadium-related revenues. Nonetheless, players would be largely excluded from revenues stemming from non-core operations like land sales or year-round businesses adjacent to ballparks. The league categorizes eight teams as sites of “ballpark districts” — mixed-use developments around stadiums — but only a small portion of revenue from these districts, such as parking fees and some signage revenue, would be shared.

Under the proposed system, player salaries would be adjusted annually to maintain their outlined revenue share, effectively establishing the salary cap. To enforce this, MLB seeks the ability to withhold up to 10 percent of player salaries in escrow each year. The union, which opposes the concept of a salary cap altogether, views the proposal as among the least favorable compared to salary cap systems in other major sports leagues like the NBA, NHL, and NFL. Meyer contended that the league’s plan combines the worst features of these systems, imposing costs such as amateur signing bonuses, interpreters, and even clubhouse meals against the players’ maximum spending threshold.

Another point of debate is the frequency of financial audits. MLB proposes allowing the union to request up to 10 audits per year among the league office and teams, fewer than the unlimited audits permitted in the NHL and NFL, and less than the NBA’s average of 15 audits annually. MLB maintains that its audit rights are comparable to those in other leagues.

The dispute reflects broader tensions regarding how player pay correlates with revenue growth. MLB argues that player compensation has lagged behind overall revenue increases, citing a 247 percent rise in league revenues since 2003 compared with a 149 percent increase in player payrolls. Conversely, the union contends that the league’s proposal would reduce player pay by hundreds of millions of dollars and lock compensation to revenue growth, potentially resulting in losses amounting to billions over time.

As negotiations continue, both sides remain far apart, particularly since players have shown reluctance to engage on the specifics of the revenue calculation given their opposition to any salary cap. MLB has expressed willingness to further negotiate the revenue-sharing terms but insists that a formal cap system would create a more consistent and balanced financial landscape for the sport. The definition and management of baseball revenue will likely remain a central issue in future collective bargaining discussions.
