Can MLB Owners Force a Salary Cap? The Lockout Law, Explained

Yes to the lockout. No to forcing the cap. Major League Baseball's collective bargaining agreement expires at 11:59 p.m. Eastern on 1 December 2026, according to CBS Sports. Once it does, the owners can lawfully lock the players out to put pressure behind their bargaining position.

That rule comes from the Supreme Court's 1965 decision in American Ship Building Co. v. NLRB, which upheld a lockout used to back a legitimate bargaining position.

A salary cap is a different thing. It is a term of employment, and federal labor law treats terms like that as mandatory subjects of bargaining under 29 U.S.C. § 158(d). An employer can't change them on its own while bargaining continues. There are only two ways for the owners to get a cap. The players' union can sign one. Or the owners can bargain in good faith to a genuine impasse and then implement terms from their last offer, the path the Supreme Court described in Brown v. Pro Football. Baseball's owners tried a version of the second path in the 1994–95 strike, and a federal judge named Sonia Sotomayor stopped them.

My verdict: Lockout, yes. Salary cap, only if the players sign.

What MLB has proposed. The league's own proposal page, Level the Playing Field, describes a seven-year deal for 2027–2033 with a salary cap of $245.3 million and a salary floor of $171.2 million. Players would get 50% of baseball revenue, and every club's local media money would be pooled and shared equally. By MLB's own illustration, using 2026 Opening Day payrolls, eight clubs would have to cut a combined $578 million to get under the cap: the Dodgers, Mets, Yankees, Blue Jays, Phillies, Red Sox, Padres and Braves. Twelve clubs would have to add $617 million to reach the floor. MLB also proposes an independent accountant to verify the financials behind the revenue split. CBS Sports dates the proposal to 28 May 2026.

The lockout. In American Ship Building the Supreme Court held that an employer does not commit an unfair labor practice when, after a bargaining impasse has been reached, it temporarily shuts down and lays off its employees for the sole purpose of bringing economic pressure to bear in support of its legitimate bargaining position. The National Labor Relations Board later applied the same logic to lockouts before an impasse, as long as the employer is backing a legitimate bargaining position and has no anti-union motive (Harter Equipment). Baseball has used this before. CBS Sports reports that the owners' 2021–22 lockout lasted 99 days and delayed the start of the 2022 season.

Why a lockout doesn't create a cap. A lockout stops the games. It doesn't change the contract terms. Under § 158(d), the duty to bargain covers wages, hours, and other terms and conditions of employment. Courts have treated a salary cap as exactly that kind of term: the Second Circuit listed salary caps among the NBA's mandatory subjects of bargaining in Wood v. NBA (1987), as Judge Sotomayor noted in 1995. After a contract expires, those terms stay frozen until there is a new agreement or a genuine impasse.

What impasse unlocks. If good-faith bargaining reaches a genuine impasse, the employer may implement new terms, but only terms reasonably comprehended within its pre-impasse proposals (Brown v. Pro Football). The bargaining itself has to be free of unfair labor practices. Impasse is a finding the labor board and the courts make. A league can't create one by announcing it.

The 1994–95 test case. The players struck on 12 August 1994. On 22 December the owners declared an impasse, without making the counterproposal the mediator had asked for, and announced they would impose a salary cap and end salary arbitration. They rescinded those changes on 3 February 1995. On 6 February they made a different set of unilateral changes: individual clubs lost authority to sign players, salary arbitration was eliminated, and the anti-collusion provision was dropped. The NLRB sought an injunction in federal court in Manhattan. On 31 March 1995 Judge Sotomayor granted it (Silverman v. MLB Player Relations Committee). She ordered the owners to restore the expired agreement's terms and bargain in good faith. At oral argument the owners admitted that an impasse had not been reached. The replacement-player Opening Day set for 2 April never happened, and the Second Circuit affirmed on 29 September 1995.

"A lockout means the owners win." A lockout is lawful pressure. It is not a way to write terms. The cap still needs the union's signature or a genuine impasse.

"Impasse is whatever the owners say it is." It isn't. In 1995 the owners called an impasse in December and, by March, admitted in court there wasn't one (Silverman). Declare it too early, impose a cap, and the labor board can go to court and put the old rules back.

"Owners can just plead poverty." They can. But in NLRB v. Truitt Manufacturing (1956) the Supreme Court sided with the labor board against a company that said it couldn't afford a raise and then refused to show its books: "If such an argument is important enough to present in the give and take of bargaining, it is important enough to require some sort of proof of its accuracy." Refusing to back up an inability-to-pay claim can support a finding of bad-faith bargaining. It isn't automatic in every case. That is one reason the league's pitch is competitive balance, not affordability. And it is why Orioles owner David Rubenstein's 15 October remark matters. Speaking at the Economic Club of Washington, he said: "A lot of my friends were buying teams, and I realized they're making money. They're making more money than I'm making in private equity" (CBS Sports; Yahoo Sports). He has also called for a cap himself.

"A floor protects small markets, so the union should want it." The floor comes packaged with the cap. CBS Sports reports that MLB's offers since May, from a 154-game season to roster changes to a higher minimum salary, are tied to the players accepting the cap. The union's interim executive director, Bruce Meyer, has called a cap "a form of institutionalized collusion" and estimated players would have lost over half a billion dollars in 2026 under MLB's numbers. That figure is the union's estimate, as reported by CBS Sports.

MLB. No salary cap in any CBA to date. The current system uses a competitive balance tax, which Commissioner Rob Manfred said in June has not done the job ("Sometimes you've got to admit you failed," as reported by CBS Sports). The league's last attempt to impose a cap without the union ended in the 1995 injunction.

NBA. The cap was bargained. In Wood v. NBA the Second Circuit treated the cap, minimum salaries and team-salary minimums as mandatory subjects of bargaining that the league and union had agreed to (as described in Silverman).

NFL. Also bargained. Brown v. Pro Football is the NFL case on what employers may do after a genuine impasse: implement terms reasonably comprehended within their last proposals, with antitrust immunity for that joint conduct (Brown).

The common thread. In each league the cap exists because the union agreed to it. Labor law gives employers the lockout as leverage. It does not give them a way to skip the union's signature on wages.

Lockout clock, as of 17 October 2026. The CBA expires at 11:59 p.m. Eastern on 1 December 2026 (CBS Sports). MLB's proposal is a $245.3 million cap and a $171.2 million floor (MLB). The Brewers have reached the World Series. They face the winner of the Guardians–Rays ALCS, and all three clubs are on MLB's own list of teams below the proposed floor (MLB).

1 December at 11:59 p.m. Eastern. CBS Sports and Yahoo Sports both report a lockout is the likely outcome if there is no deal.

The word "impasse." Any owner talk of an impasse is the start of the legal fight, not the end of it. It is what 1995 turned on.

The string on every offer. Watch whether MLB ever stops tying its other proposals to the cap. If that string comes off, a deal gets close. If it doesn't, plan on a long winter.

The TV clock. The Athletic has reported, per CBS Sports, that if a stoppage costs 60 or more games, most of MLB's national TV and streaming deals extend a year, through 2029. That gives the owners their own reason not to let a lockout run into summer.
