The Knicks won the 2026 NBA Championship and Jalen Brunson was Finals MVP. If you had his cards before June, you made money. The question now is what happens next -- and whether the market has already priced in everything Brunson is.
The short answer: the big move happened. But that does not mean the cards are done. It means you need to be clear-eyed about what you are buying and why.
The Silver Prizm RC PSA 10 -- the benchmark card -- ran up hard during the Finals and has since settled into the $290 to $555 range, depending on condition within the grade and platform. That is a significant cooldown from the peak during the championship run, but still well above where the card was trading two years ago.
The Nebula 1/1 sale at $312,000 on Fanatics Collect was a record by a wide margin -- his previous high was $96,660. That kind of comping only happens when a player just became a champion. The grail market tells you the ceiling. The Silver Prizm PSA 10 tells you what most collectors are actually transacting on.
Brunson's championship thesis played out. He averaged 32.6 points per game in the Finals, dropped 45 in the clincher, and won MVP. The Knicks ended a 53-year title drought. That is as good a catalyst as exists in the hobby, and the cards responded.
Here is what buying now actually means: you are buying after the catalyst, not before it. The Silver Prizm RC PSA 10 at $400 is not the same trade as it was at $150 two years ago. That does not make it a bad buy -- it makes it a different buy, with a different thesis.
Brunson is 29 years old, the undisputed best player on an Eastern Conference title contender, and just had the highest-profile performance of his career on the biggest stage. If the Knicks contend for multiple championships over the next three to five years, and Brunson builds a legitimate Hall of Fame case -- scoring titles, All-NBA selections, more Finals runs -- the Silver Prizm PSA 10 at $500 will look cheap. Players with rings and HOF cases hold value. That is the buy thesis today.
Championship pops are notorious for retracing. The card already ran from roughly $150 to $600-plus during the Finals window. The current $290-$555 range reflects real cooling. If Brunson gets injured, the Knicks regress, or collectors move on to the next story, the Silver Prizm PSA 10 at $400 could drift back toward $200. Buying a card that just had its major catalyst is always a higher-risk entry than buying before it.
Most liquid Brunson card, most comparable sales data, easiest to exit. If you are buying Brunson to hold for 2 to 3 years and believe in his continued production, this is the right card. The $290 to $555 range gives you room to pick your entry. Do not overpay for a "clean" PSA 10 -- they are all PSA 10s.
Seventy-five copies is real scarcity without being so rare that the market is thin. These trade less often but hold value better during market downturns because the supply is fixed. If you are buying with a five-year horizon, the Purple /75 is worth the premium over the base Silver.
The Silver PSA 10 selling at $290 to $555 versus the SGC 10 at $200 to $380 is a scenario where the grader premium math actually starts to look interesting. At $250 SGC vs. $450 PSA for essentially the same card, the PSA premium is real but so is the price difference. If you are buying to hold and do not need to sell quickly, SGC is worth considering here.
Raw (ungraded) Brunson Prizm RCs at inflated prices. After a championship pop, raw card prices chase graded comps but without the grading verification, population data, or liquidity of a slabbed card. If you are buying raw to grade yourself, make sure the card actually grades out -- centering and surface issues are common on 2018 Prizm base cards.
Brunson's card market moves with his basketball story. The next chapter that would drive another meaningful leg up: a second championship, an MVP award, or consistent All-NBA First Team selections that cement the Hall of Fame case. Any of those events would re-price the Silver Prizm PSA 10 higher, because the market will re-evaluate his historical standing.
What would bring cards lower: injury, decline in production, or the Knicks falling back to the pack. The NBA is unpredictable, and so is the card market that follows it.
The championship is priced in. What happens next is not.
