A coalition of Major League Baseball owners is circulating term sheets for a hard salary cap modeled on NBA and NFL structures, according to people familiar with league-level conversations. The push comes as average MLB franchise valuations trail the NBA by roughly $2 billion and the NFL by even more, despite baseball's comparable media footprints and longer seasons. The gap has become a governance problem: newer ownership groups who paid premium prices in 2021 and 2022 now sit on assets that appreciated less than their basketball counterparts bought the same year.

The median MLB club is worth approximately $2.3 billion as of early 2025, per Forbes and Sportico estimates. The median NBA franchise sits near $4.2 billion. NFL clubs average north of $5 billion. All three leagues share similar local media models, national broadcast deals in the mid-nine figures, and comparable debt-service ratios. The delta is structural: MLB has no payroll ceiling, which means no guaranteed floor on EBITDA margins, which means private-equity underwriters and family offices apply a lower multiple to baseball cash flows. Debt markets price the same risk; MLB acquisition loans carry 40 to 60 basis points more than NBA equivalents, even when secured by comparable revenue.

Owners pressing for a cap cite the NBA's 2011 reset, when a hard cap paired with basketball-related income splits lifted franchise values 80 percent in four years. MLB's last Collective Bargaining Agreement, signed in 2022, introduced a competitive-balance tax but left the high end uncapped. The Yankees, Mets, and Dodgers routinely carry payrolls above $300 million; the Athletics and Rays stay below $80 million. That spread creates two problems. First, it fragments the buyer universe: institutional allocators prefer assets with predictable expense bands. Second, it suppresses exit multiples when sellers comps their deals to the NBA, where every franchise operates inside a narrow cost range and throws off similar incremental margins.

The expansion subplot is relevant. Sacramento just declared interest in a franchise; a California city is circulating a $2 billion public-private ballpark plan with a World Series-winning manager on the bid committee. Both bids are modeling franchise fees in the $2.5 billion to $3 billion range, which only pencils if future buyers believe MLB clubs will trade at NBA-like multiples within a decade. Expansion proceeds are split evenly among existing owners, but the real prize is peer-set valuation: if expansion franchises trade at $3 billion, legacy clubs get marked to that number in credit facilities and estate planning. A hard cap accelerates that markup by signaling that baseball has closed the structural discount.

Resistance will come from the union and from large-market clubs whose competitive advantage is payroll flexibility. The Players Association has historically opposed caps as suppressing total salary spend, even when paired with revenue floors. The Dodgers and Yankees, meanwhile, view uncapped spending as a moat; their local media deals and gate revenue can support $400 million payrolls that smaller clubs cannot match. Any cap proposal would need to include a true salary floor—likely 75 to 80 percent of the cap—to pass union scrutiny, and that floor would force low-revenue clubs to spend more than they do now. The politics are ugly but the arithmetic is clean: a $250 million cap with a $200 million floor would narrow team payrolls to a $50 million band, compress EBITDA variance, and make every club a cleaner comp for the next buyer.

Timing matters. The current CBA runs through December 2026. Preliminary bargaining begins in early 2026, roughly when expansion bids will be formalized and the league will want to announce new markets. If owners table a cap proposal in that window, the union will demand higher revenue shares and shorter service-time clocks in return. The baseline ask is probably a 50-50 revenue split, mirroring the NBA, up from baseball's current 40-60 tilt toward owners. Whether the league's largest revenue clubs will accept that math to unlock a $1 billion to $2 billion bump in franchise value is the trade every owner is running in private.

Expansion cities are already underwriting the upside. Bid committees are stacking their rosters with ex-players, civic heavyweights, and infrastructure commitments that assume MLB franchises will be worth what NBA teams are worth by 2030. If the cap goes through, they are right. If it does not, the gap persists, and baseball remains the league where a top-three market team is worth what a mid-market basketball team commands.
