Baseball's owners want a salary cap. It could cost them a whole season.

The fight that could stop baseball

Major League Baseball’s owners have proposed something the sport has never had: a hard cap on what teams can spend on players. Their offer, made in late May, would let teams spend no more than $245.3 million on salary, with a mandated floor of $171.2 million [49]. Baseball is the only major U.S. league with neither a cap nor a floor today [49].

A salary cap is a ceiling on a team’s total payroll. A floor is a minimum it must spend. Together they squeeze every team’s spending into the same band — in theory, so a rich club can’t simply buy the best players and a poor one can’t pocket the money instead of competing.

The players’ union hated it. Bruce Meyer, the union’s interim head, said he was “very surprised” by the details and that the owners “didn’t even” try to make the offer look good [49]. The union’s own analysis found that had the cap been in place this year, players would have lost over half a billion dollars [49]. Amateur players signing their first pro deals would be hit hardest, the union said [49].

Here is the mechanism the fight turns on. A cap usually comes bundled with a revenue split — an agreed share of all the money the sport earns that goes to players. The owners proposed a 50-50 split [49]. The union says players already take more than half, so “50-50” is a pay cut dressed up as fairness [49]. The argument isn’t really about a number; it’s about which side the spare money flows to.

Why the commissioner is talking about parity

The owners are selling the cap on “competitive balance” — the idea that small-market teams can’t keep up with big spenders. Commissioner Rob Manfred made that case by declaring the old system broken. “We have tried mightily over several rounds of bargaining to use a competitive balance tax to address competitive concerns, and sometimes, you got to admit you failed,” he said [18].

The “competitive balance tax” is baseball’s current tool, better known as the luxury tax. There’s no hard ceiling; instead, a team that spends past a threshold pays a penalty on the overage. The idea is to make heavy spending expensive enough to deter it. Manfred’s point: the penalty hasn’t stopped the biggest clubs from spending anyway [18].

Whether the problem is even real is contested. Manfred himself has praised baseball’s parity in the past, and the season has produced an all-National-League top three in the power rankings [18]. The “fans can’t stand the imbalance” framing is the owners’ argument, not settled fact.

What makes this dangerous is history. The last time owners pushed hard for a cap, players walked. The 1994-95 strike ran 232 days and canceled a World Series [18]. Asked whether he worries about a repeat, Manfred said: “Of course I do. Of course I do” [18]. He worked for MLB as outside counsel during that strike [18]. The current labor deal expires in December, and a new one likely needs to be in place by mid-March to save the 2027 season [18]. One union negotiator already calls a work stoppage “a real threat” [43].

One machine, many headlines

The cap fight looks like a baseball story. It’s really one corner of a bigger machine: how leagues use collective power to control money, and who pays when they do.

Look at the National Football League this week. Congress has summoned commissioner Roger Goodell to testify on June 10 about the league’s TV deals and whether they’re hurting fans [9]. The trigger is a 1961 law, the Sports Broadcasting Act, that handed leagues a limited antitrust exemption — permission to sell their games as one bloc instead of team by team [9]. “Back when the Sports Broadcast Act was passed, the promise was you’ll get to watch every one of your team’s games for free,” said Rep. Jim Jordan, who chairs the House Judiciary Committee [9]. Now games are scattered across streaming services, and watching your team costs more and takes more apps. The Department of Justice opened its own investigation in April into whether that exemption still covers the streaming era [9]. (Goodell has declined to appear [3].)

Baseball’s blackout fight is the same machine from another angle. MLB’s labor proposal would, over time, let the league dismantle the territorial TV system that blacks out local games [4]. That system is why you sometimes can’t watch your own team even with a paid streaming package [4]. It exists because TV rights are sold by territory — and untangling it is now a bargaining chip.

College sport runs on the same logic. A landmark federal bill would, among other things, let conferences pool their media rights into one package [60]. The two richest leagues, the SEC and Big Ten, withheld support, saying it leaves “critical issues unresolved” [60]. Pooling rights is exactly the bloc-selling power the 1961 NFL law granted — and the richest conferences would rather not share the leverage.

The thread through all of it: leagues are most valuable when they act as one seller. Caps, blackouts, pooled rights and antitrust exemptions are all versions of teams agreeing not to compete with each other off the field, so they can charge more for what happens on it.

When the cap has to be enforced

A cap is only as real as the league’s willingness to police it — and policing is messy. The NBA has spent since September investigating whether the Los Angeles Clippers arranged a no-work, multi-million-dollar endorsement deal for star Kawhi Leonard through a team sponsor, a way to pay him outside the cap [34]. Commissioner Adam Silver said this week the league is “close to the point now where I think we need to wrap this up” and “can’t be investigating forever” [34]. The NBA has interviewed Leonard and his adviser [16].

That’s the catch built into every cap. The harder you cap spending, the bigger the incentive to route money around the cap — through endorsements, sponsors, side deals. The rule creates the workaround it then has to chase. It’s the same pressure that will land on baseball the day a cap exists.

The bet on his own name

End with the quieter story, because it shows where the money machine is heading next: into prediction markets, where the line between a bet and a trade is blurring.

Federal authorities are reportedly investigating George Santos, the former congressman, over a bet he placed on Kalshi — a prediction market where people wager on real-world events [73]. The wager was on whether he himself would attend Trump’s State of the Union address [73]. He’d announced he would go, then said travel problems stopped him [73]. Kalshi flagged the trade to regulators [73]. The shape of the concern is insider trading: betting on an outcome you control or know in advance [73]. (The reporting cites anonymous sources; nothing is charged [73].)

Traditional gambling regulators are busy too. An Australian state regulator fined the Star Sydney casino $7.2 million for risk-management failures [71]. As sports betting and prediction markets spread, the rules written for old-fashioned bookmaking are straining to cover wagers that look more like financial trades — and the people best placed to profit are the ones closest to the outcome.
