The basics
What is CardZ Marketcap?
CardZ Marketcap is a daily market capitalisation index for graded trading cards. It ranks Pokémon and One Piece cards by verified PSA 10 population multiplied by PSA 10 reference price, and publishes the effective date of every snapshot.
What is a PSA 10 market cap?
A PSA 10 market cap is the price of one PSA 10 copy multiplied by the number of PSA 10 copies PSA has graded. It expresses how much value sits in a card's top-grade supply rather than in a single copy.
Is CardZ a cryptocurrency or a token?
No. CardZ Marketcap is a trading card price index with no token, no coin and no ticker. It is unrelated to any crypto asset trading under a similar name, and nothing on this site can be bought or sold.
Is CardZ Marketcap free to use?
Yes. The rankings, card pages, methodology and glossary are free to read, and the figures are free to quote with attribution and a link back to the page you took them from.
How the numbers are built
How is trading card market cap calculated?
Market cap equals PSA 10 reference price multiplied by verified PSA 10 population for the same printing. Both inputs carry an observation date, and a card is held out of the ranking if either input cannot be verified.
Where does the population data come from?
Population comes from PSA's published population report, matched to the exact set, card number, language and finish. We use the PSA 10 count only; lower grades are not part of the market cap figure.
How often do the numbers update?
The published snapshot is rebuilt daily. Each card shows when its price and population were observed, so a figure that has not moved recently is visibly dated rather than silently refreshed.
Why do some cards show no number?
Because the value could not be verified for that printing on that date. CardZ Marketcap leaves unverified values blank instead of substituting zero or estimating, which would quietly corrupt the ranking.
Which currency are the figures in?
Figures are computed in US dollars and converted for display using the exchange rate stored with the snapshot. Switching currency changes the display only; the underlying ranking never changes with it.
Coverage
Which cards are covered?
The index covers Pokémon and One Piece single cards that have a verified PSA 10 population and a price we can stand behind. As of 2026-10-13 it ranks 1,677 printings: 0 Pokémon and 0 One Piece.
Are Japanese and English cards ranked separately?
Yes. Each printing is a separate row because each has its own population and its own price. The same artwork in another language is a different card for ranking purposes, never an average of the two.
Do you cover sealed boxes?
Sealed product is tracked separately from single cards. It has no PSA 10 population, so it cannot enter the single-card market cap ranking and is never mixed into those totals.
What is the total market cap tracked?
As of 2026-10-13, the published index tracks $4,787,359,447 in PSA 10 market cap across 1,677 printings. That total moves daily with prices and with newly graded copies entering the population reports.
Reading the rankings
What are the most valuable Pokémon cards by market cap?
The ranking is published live and reorders daily. Market cap leaders combine a high PSA 10 price with a large graded population, so the top of the list is rarely the same as a list of the most expensive single cards.
Why is a cheap card ranked above an expensive one?
Because market cap multiplies price by supply. A card worth $30 with 300,000 PSA 10 copies carries more total value than a card worth $30,000 with 40 copies, even though one copy costs far less.
Can I use these figures in an article or a video?
Yes, with attribution to CardZ Marketcap and a link to the page you took the figure from. Please include the effective date, because market cap figures change every day.
CardZ Marketcap is a trading card price index. It is not a cryptocurrency, not a token, and not a listed company. There is no CardZ ticker, and this site is unrelated to the crypto asset traded as CARDS.
