Quick answer: An MLB lockout freezes every prospect on a 40-man roster, including prospects who just debuted and guys added this November for Rule 5 protection. Minor leaguers not on a 40-man play a full season and may gain hobby attention. The group facing the most card value risk is the 2027 debut class, especially older college bats whose timeline pushes past age 23.

The current collective bargaining agreement expires at 11:59 p.m. on December 1, 2026. Almost nobody around the sport expects a deal before then. Prediction markets had the "no new CBA by December 2" side trading in the low 90s as of mid-August. Union leadership has been telling players for a couple of years to save their money.

So a lockout is close to a given. What isn't a given is how long it runs, and that's the part that actually matters for prospects and for the cards attached to them.

Here's how I'm thinking about it.

Which prospects does an MLB lockout affect?

Any prospect on a 40-man roster gets locked out along with the veterans. No spring training, no team facilities, no coaching contact, no games. That was the shape of the 2021-22 lockout and there's no reason to expect anything different.

Two things collectors tend to get wrong here.

Rule 5 protection puts more prospects in the frozen bucket

This group is bigger than just guys who have debuted. Players get added to the 40-man in November purely for Rule 5 protection, typically after their fourth or fifth pro season, without ever having appeared in a big league game. That deadline falls around November 20, comfortably ahead of the CBA expiration, so those additions happen normally and then those players are locked out along with everyone else. Once a lockout starts, all transactions freeze, so nobody gets added after the fact.

Getting optioned to Triple-A doesn't remove a player from the 40-man

Optioning and removal are two different mechanisms and they get conflated constantly. An option is a roster shuffle where the player stays on the 40-man. Actual removal requires a designated for assignment, then waivers, then an outright or release. That's a transaction where the club is genuinely giving up on the player. It doesn't happen to real prospects.

Kade Anderson is the clean example. He debuted Saturday against the Cubs, going 5 2/3 innings with five strikeouts before back-to-back homers from Bregman and Busch ended his night. He's on the 40-man now. Even if Seattle sends him back to Tacoma to finish the year, he stays on it, and he stays locked out.

If you're a rules person and I've got any of this wrong, tell me. This is the section where I'm most exposed.

Do MLB prospects keep playing during a lockout?

Yes. Minor leaguers who aren't on a 40-man roster aren't party to the dispute. They report, they play a full season, they get their reps.

My read is that this group may actually see a hobby boost. Baseball fans who lose their major league fix have to point their attention somewhere, and the natural landing spot is the up and comers. More eyeballs on Double-A, more people actually watching the guys whose cards they own.

The counterpoint worth taking seriously: does the entire card market take a hit when a major sport goes dark, dragging prospects down with it? I doubt it, but I wouldn't dismiss it either. That's a thing to watch rather than a thing to assume.

Which prospects lose the most from an MLB lockout?

This is the group I'd actually worry about, and it's the piece of this that's specific to the hobby rather than to baseball.

Guys projected to debut in 2027 get their timeline pushed. For younger prospects that's survivable. For older ones it compounds in a way that hits card values directly.

Andrew Fischer is the example I keep coming back to. Milwaukee took him 20th overall in 2025 out of Tennessee. He was born in May 2004, which means a delayed debut landing in 2028 puts him at 24 at callup.

Age absolutely moves hobby buzz, and roughly 23 tends to be the line. Cross it and the "future star" framing gets harder to sustain, regardless of what the bat is actually doing. A lockout that eats a year doesn't just delay the payoff on these cards. For the older college bats it can permanently reprice them.

How long will the MLB lockout last?

Here's my call: I think at least half the 2027 season gets lost.

That puts me in the pessimistic camp, but not at the extreme. One agent surveyed recently said he doesn't expect meaningful baseball until June, if not July, on the logic that Manfred won't move until public pressure builds, and public pressure requires real games to be lost. Jeff Passan has reported that some owners don't expect baseball to be played at all in 2027, and there are people across the industry who think a fully lost season is live.

The core issue is a salary cap. Owners proposed one for the first time since 1994. The first offer was a $171.2M floor and a $245.3M hard cap, which the union says also cuts the players' share of revenue. Both sides are dug in on something neither has historically been willing to trade away.

The case for a shorter lockout

These things settle at the deadline. The 2021-22 lockout ran 99 days and cost zero games. Opening Day moved from March 31 to April 7 and the cancelled series got rescheduled. The AP's Ronald Blum framed the timeline well: nothing means anything until the first two weeks of March 2027, because you can posture about a cap right up until you're staring at lost revenue, and that's when people show their cards.

There's also a structural cushion. MLB's deals with ESPN, NBC, Netflix, Fox, TBS, and Apple all contain clauses extending them an extra season if significant games are lost.

One historical note worth getting right, because it cuts against my own prediction: no MLB lockout has ever cost regular season games. The stoppage that did was the 1994-95 strike, which was player-initiated, ran seven months, killed the World Series, and shortened 1995 to 144 games. If I'm right about half a season, I'm predicting something a lockout has never actually done.

MLB lockout prospects: the bottom line

Three buckets:

Frozen: 40-man players, including recent debuts and November Rule 5 additions. Development stalls, no games, no facilities.
Playing: Non-40-man minor leaguers. Full season, and potentially more hobby attention than they would otherwise get.
At risk: The 2027 debut class, especially older college bats. Longest tail, hardest to recover from.

All of this is conjecture. Maybe there's no lockout. Maybe it's short. And the card market today looks nothing like it did during any prior work stoppage, which means the historical comps are thin to begin with.

Time will tell.
