You’ll notice something odd if you walk into any card shop in late May. Compared to a hobby store, the energy is more akin to a small trading floor. Phones are ringing. Someone laughing nervously while pulling a Bowman Chrome pack. A man standing close to the counter is holding a sleeved DeLauter rookie as if he’s debating whether to sell it or hold off for another week. The rookie card market is acting like it’s August even though the 2026 MLB season is only six weeks old.
This year seems different, but it’s still unclear if that impression will last. The hobby has always been shaped by early call-ups, but the current rate of price movement seems out of the ordinary. In just a few weeks, Chase DeLauter’s Bowman Chrome car went from $185 to $260, and he hit five home runs in his first month with Cleveland. That represents a 40% increase on a card that some collectors thought was overpriced back in March. It appears that the market is unconcerned.

I find Munetaka Murakami’s story to be more fascinating. In April, his Topps Series 1 base card was worth about eight dollars. Due almost entirely to his move from NPB to the White Sox, it was trading close to $22 by the beginning of May. In the past, a 175 percent gain on a base card might occur once or twice a season. Now that several players are experiencing it simultaneously, it begs the question of whether this is a wave of speculative buying chasing the next short-term spike or if there is actual demand.
Red Sox outfielder Roman Anthony has emerged as the group’s slow burn. The price of his Bowman Chrome refractor increased from $45 to $68, which may seem insignificant until you consider that refractors are manufactured in far greater quantities than cars. A high-print card’s consistent appreciation typically indicates genuine collector interest rather than flipper activity. Similar circumstances apply to Jac Caglianone, whose Topps Series 1 auto has increased by 45% since Opening Day.
Here, the larger context of hobbies is important. In 2026 Bowman, Topps reduced the number of packs by reducing value boxes from twelve cards per pack to ten and jumbo boxes from 24 packs of eight cards to 20 packs. Collectors took notice right away. Some people are upset. In the hopes that fewer print runs will result in greater long-term value, some are covertly purchasing more. Even though Topps hasn’t stated it in public, it appears to be a calculated decision on their part.
A cultural change is taking place outside of the corporate scheming. Rookie cards are at the more speculative end of the memorabilia market, which is expected to reach $227 billion by 2032. The single highest-leverage wager in the hobby, according to investors, is to catch a player within the first thirty days of their debut. The events of June, July, and August will determine whether or not they are correct. The All-Star break has caused many fast starters to fade. Many haven’t.
The extent to which the market favors visible production over projection is difficult to overlook. Traditional collectors used to follow scouting reports, draft positions, and pedigrees. These days, box scores and social media clips are posted every day. Before the postgame interview concludes, DeLauter’s card prices could be moved by a two-homer night. That pace is both thrilling and a little unnerving, and longtime hobby shop owners I’ve casually spoken to seem genuinely uncertain about its future.
For some of these names, three times the pack price isn’t even the upper limit at this time. It’s the ground. The real question is whether that lasts through summer, and no one seems to know for sure—not even the sellers.
