Major League Baseball and its players are heading into what could be a long, contentious summer of negotiations, and traders on Polymarket currently put the odds of a deal getting done by December 1 at less than 40%. However, that number shifts with every development at the bargaining table.
That deadline matters. The current Collective Bargaining Agreement, the contract that sets the rules for salaries, team spending and working conditions across the sport, expires on December 1, 2026.
If no new deal is in place by then, team owners are expected to lock players out, just as they did in 2021-22. That standoff lasted through the winter and cut into spring training before a deal was finally reached in March 2022.
New MLB CBA Odds, Predictions
Both sides exchanged their opening proposals in late May. The distance between them is significant.
Owners want a hard salary cap, a maximum limit on what any team can spend on players, along with a salary floor that would require all teams to spend at least a minimum amount.
They argue that without a cap, a handful of wealthy teams dominate the sport year after year. Commissioner Rob Manfred pointed out that since 2012, the NFL, NBA and NHL have each seen multiple smaller-market teams win championships, while baseball's only bottom-15 market World Series winner was the 2015 Kansas City Royals.
The players, through their union, the MLB Players Association, have flatly rejected any salary cap. Their proposal focuses on raising minimum salaries, expanding free-agent eligibility and reforming revenue sharing so that smaller-market teams receive more money, with conditions requiring them to actually spend it on their rosters.
MLBPA interim executive director Bruce Meyer called the owners' proposal "the worst system for any players in any major sport, and not even close." Manfred, for his part, pushed back and insisted that under the league's plan, players would collectively earn more in 2027 than they do today.
Why a Deal by December 1 Looks Difficult
The core disagreement is not just about money: it's about the fundamental structure of the sport's economy.
Owners want a system with a hard cap and floor and centralized TV revenue sharing. The players want to preserve and improve the current market-based system. Those are very different starting points.
Neither side has scheduled a follow-up meeting. The next owners' meetings aren't until November, days before the CBA expires, which leaves a narrow window for real negotiation.
There's also a historical pattern here. During the 2021 dispute, MLB took three months to counter the union's opening pitch. While the League countered within 24 hours this time, the structural gap regarding revenue splits and franchise valuations is significantly wider.
Why a Deal Is Still Possible
A work stoppage would hurt both sides. If games are canceled in 2027, MLB risks damaging the national television deals it needs to negotiate after the 2028 season, a potentially massive source of revenue for owners and players alike.
Owners have also shown some flexibility in their public messaging. Manfred has said he's open to a process in which both sides work toward each other's goals, rather than just their opening positions. And despite the sharp rhetoric, early exchanges in labor negotiations are almost always exaggerated; both sides stake out extreme positions before looking for middle ground.
For now, the market says it's more likely than not that December 1 will come and go without a deal. Whether that changes will depend on how quickly or slowly both sides decide to actually get to the table.
