The Tape

The hobby heads into World Series week riding two currents at once. On one side: a record-shattering basketball card sale just reminded everyone why the high end refuses to cool off. On the other: a federal antitrust case over grading-market consolidation is still sitting with a judge, unresolved, three weeks after its big hearing. Add rookie quarterback cards swinging wildly week to week and a market-growth report warning that overproduction is quietly compressing base-card values again, and the mood is best described as bullish at the top, jittery in the middle. MLB’s Wild Card Series tips off Tuesday, and if history holds, postseason heroics are about to move a lot of cardboard.

Top Stories

A one-of-one just became the third-most valuable NBA card in history. Cooper Flagg’s autographed NBA debut patch card sold through a Fanatics Collect auction on September 25, per ESPN, landing as the third-most expensive basketball card ever sold and, per Topps, the priciest single-player NBA card on record. Two Mavericks rookie classmates, Dylan Harper and Kon Knueppel, also moved for seven figures in the same sale. The auction underscores how aggressively Fanatics is now positioning itself as manufacturer, vault custodian, and auction house all at once for the hobby’s marquee rookies, rather than routing that inventory through third-party houses.

The PSA antitrust case is still in limbo, and that’s itself the story. Back in April, a proposed class action accused Collectors Holdings, PSA’s parent, of building an illegal grading monopoly through its acquisitions of SGC and Beckett. Collectors Holdings fired back in June with dueling motions: one to compel arbitration and kill the case outright, another arguing the complaint doesn’t hold up on the merits. Both were argued before Judge John W. Holcomb in the Central District of California on September 11. Two and a half weeks later, no public ruling has surfaced. Whichever way it breaks, the decision determines whether allegations about pricing and turnaround practices across PSA, SGC, and Beckett get argued in open court with discovery, or get shuffled into private arbitration. Worth watching closely, since it’s the single biggest structural question hanging over the grading industry right now.

MLB’s postseason opens Tuesday, and the hobby is already positioning for it. Wild Card Series play begins September 29, with the Division Series following October 3 and the World Series set for October 23, per CBS Sports. Rookie and star performances during October have historically been one of the fastest catalysts for card price moves in the calendar year, and this year’s field arrives with several rookie-class storylines already in motion (see Movers Desk).

Football is where the volatility lives right now. Cardcenteringtool’s most recent read (dated September 27) has rookie quarterback cards broadly climbing on early-season performance: Caleb Williams and JJ McCarthy rookie cards both showed strong gains, alongside Josh Allen, Kyler Murray, and Patrick Mahomes base cards ticking higher. That’s a notable reversal from the picture just a few weeks earlier, when McCarthy’s card had reportedly been sliding hard alongside other unproven rookie arms, a reminder of just how fast sentiment swings on a handful of Sunday performances. Vintage football is quietly participating too, with early-1900s and mid-century names like Jim Brown and Kenny Washington posting outsized gains as collectors rotate into scarcer, condition-verified supply.

Baseball’s storylines are just as sharp heading into the postseason. Pete Crow-Armstrong’s rookie autograph has been one of the season’s biggest gainers amid a tight NL MVP race, while Cal Raleigh’s rookie refractor has cooled substantially in the back half of the year as his power numbers came back to earth. Both are textbook cases of performance-driven repricing rather than anything structural, and both are worth watching closely once playoff at-bats start counting.

On the basketball side, the Flagg sale (see Top Stories) is pulling the entire Mavericks rookie class along with it, evidence that a single marquee result can re-rate an adjacent tier of cards almost overnight.

PSA rolled out a new, lower-cost Standard service tier in mid-September, alongside a rebrand of its existing lineup: Regular is now Priority, and Walk-Through is now Premier, according to ICv2 (September 22). The company also opened its first dedicated European grading facility, in Frankfurt, enabling direct submissions from EU collectors for the first time. That expansion comes even as the Value tier backlog remains stuck near 9.9 million cards, still paused while PSA works through the queue.

CGC, meanwhile, implemented a price increase across its cards, comics, video game, and home video grading lines effective in January, per Sports Illustrated, a move framed as unsurprising given CGC’s climb to the number-two spot among card graders after SGC’s post-acquisition pivot toward more boutique volumes. GemRate’s August 2026 recap shows the broader population story is still one of growth: total grading activity ticked down modestly month over month but remains up sharply year over year, with CGC and TAG both setting record monthly volumes even as PSA’s backlog constrains its own throughput.

Catalyst Calendar

• September 29 – October 1: MLB Wild Card Series. First real postseason test of rookie and star card demand this fall.
• October 3+: MLB Division Series begins.
• October 11+: League Championship Series (no earlier than).
• October 23: World Series begins; a potential Game 7 would fall on October 31.
• Pending, no fixed date: Ruling on Collectors Holdings’ motions to compel arbitration and dismiss the PSA antitrust case, argued September 11 before Judge Holcomb. This is the single most consequential near-term event for the grading industry’s structure.
• Ongoing through October: NFL rookie quarterback card values likely to keep swinging week to week as the season progresses.

Fanatics continues to vertically integrate the high end of the hobby. Beyond the Flagg auction, the company’s Topps Instant Packs product, which lets collectors buy individual premium packs digitally with the physical cards held in the Fanatics Vault, expanded through late August and September, per Bleacher Nation and Fanatics Collect’s own newsroom. The model is designed to cut down on secondary-market scalping, though there are open questions about how clearly the odds are disclosed to buyers.

Further back but still shaping the landscape: CardsHQ’s merger with Sports Card Investor, backed by new investment from Shamrock Capital and EnOne Ventures, remains one of the year’s clearest signals that private capital sees a durable, consolidating commerce-and-media layer forming around the hobby, not just a grading-side story.

Bottom Line

Three threads to hold onto this week. First, the top of the market has never looked stronger. The Flagg sale is proof that scarce, first-ballot rookie cards with real pedigree and a clean paper trail keep setting new ceilings, independent of what’s happening anywhere else in the hobby. Second, the grading industry’s structural risk hasn’t gone away just because it’s stopped making headlines. A ruling on the Collectors Holdings antitrust case could land any day, and it will matter far more to long-term collectors and investors than any single auction result. Third, October is about to become the market’s biggest real-time stress test in months, with MLB’s postseason starting Tuesday and NFL rookie values already whipsawing on a weekly basis. Position for volatility, not certainty, and keep your eyes on the desks that don’t make flashy headlines: grading capacity, courtroom dockets, and population reports are still where the next real move gets decided first.
