Why now

In December 2025 one card, a Japanese McDonald's promo Pikachu, was graded 58,000 times in a single month (Sports Illustrated, Jan 2026). That is fifty-eight thousand copies of the same card, each sealed in plastic with a grade on the label, each priced against every other copy at that grade. It is not a curiosity. It is a market, with a price for every one of those slabs and, until Quanta, no price for the whole.

Quanta exists because three things lined up for that market. Cards became comparable. Their sales became a record anyone can read. And a network with a dollar gave the result a place to trade and an audience to reach. All three had to be in place first.

The hobby outgrew its price tools

The graded card market is large and still growing. Major authenticators graded 26.6 million cards in 2025, 32% more than the year before; trading card games and other non-sport cards made up 16.8 million of those, close to double the prior year, and Pokémon alone 16.1 million (GemRate via Yahoo Sports, Jan 2026). On eBay, card singles sold for $2.62 billion in 2025 across 61.5 million transactions (GemRate via Yahoo Sports, Jan 2026).

The press took notice, and so did lawmakers. As a childhood hobby becomes an asset class… Bloomberg, April 2026. Trading cards are no longer simply consumer products. Japan's ruling LDP, via Japan Times, July 2026.

The category indexes tell the same story. Card Ladder's Pokémon index, which follows high-grade graded cards sold on eBay and other marketplaces, stood at +170.27% year to date (Card Ladder, as of 13 Sep 2026). Its CL50, fifty headline sports cards, dropped 23% in 2022 and a further 9% in 2023 (Sports Illustrated, Jan 2026). A category-wide number has existed for years and has moved a long way in both directions, yet nobody could take a position on it. You could read the chart, not trade it. The same Card Ladder sales data now drives the 44-index Quanta board, where those category levels become something you can act on.

Three shifts closed that gap, each one solving the problem the one before it uncovered.

Grading made cards comparable

An ungraded card is one of a kind. Two copies of the same card differ in centering, surface, edges and corners, and that is exactly what two collectors argue about when they argue price. Grading settles most of that. A PSA 10 of a given card is priced as the same object whether it sits in a display case in Osaka or a safe in Ohio.

That is what makes a category priceable. An index needs constituents that trade again and again, and a card only works as a constituent if this week's sale and last week's sale are sales of the same thing. Raw cards never offered that. Slabs offer it at scale: PSA alone graded 19.26 million cards in 2025, 72% of the total (GemRate via Yahoo Sports, Jan 2026), and around six million Pokémon cards came onto the market as PSA 10 slabs that year (Sports Illustrated, Jan 2026).

With comparable objects in place, the next step was the record. Data companies such as Card Ladder gather graded card sales from the major marketplaces and auction houses into long category histories. Vaulting added a second kind of record: a sale written to a public chain that anyone can check.

Vaulting made sales public

The second shift put the slab in a vault and its ownership on a blockchain. Graded cards now sit in insured professional vaults, and each one is a token carrying its grader, grade, set and card number, tied to the physical item by a fingerprint that never changes. When the card sells, the token moves and payment settles on-chain in USDC, on Polygon, with the price, the time and both parties on public record. The card stays put. The record moves.

Collectors can pay by card and never touch a wallet; in Polygon Labs' words, one click, no gas fee, because the platform is paying that on behalf of the user (Polygon Labs, Feb 2024). They did not sign up for crypto. They signed up for a marketplace that settles in public, and volume followed. The largest on-chain vault for graded cards has run on Polygon since 2023 (the vault operator's migration notice, Aug 2023). Its daily trades climbed from about 10,000 in late 2025 to over 50,000 on many days in 2026 (Privy, Aug 2026); August 2026 was its biggest month, around $138 million of venue volume (DefiLlama, Sep 2026); its public listing showed about 376,000 items across more than 40 categories, roughly 68% of them Pokémon (the vault's public marketplace listing, 15 Sep 2026).

For anyone building an index, that is a new kind of input. Every sale is a fact you can check against the chain. Every item carries its grade, so the mapping from token to constituent (the dictionary) can be built once and frozen. Every counterparty is an address, so trades looping between the same wallets are visible, which is what lets the methodology remove them. The Quanta index engine reads that record as its verifiable settlement layer. The details are on The data source.

A network with a dollar

The third shift is what makes the price tradable. A record of sales is something to read; taking a position on it needs a market, a dollar to count in and a network that settles at any hour. The Quanta DEX runs on Solana, a public blockchain where a transaction sent from your own wallet settles fast and costs little. Its markets take USDC, a dollar stablecoin, as collateral, and count margin, profit and loss, fees and funding in that same USDC, so every number reads in dollars and nothing you deposit gets converted.

Reach is the reason. Slate called Pokémon cards Gen Z's favorite financial asset (Slate, Aug 2026); the person who owns a slabbed Charizard and the person who trades from a phone are very often the same person. Quanta runs on Solana so that the first tradable index on physical collectibles is one wallet connection away from that person. The vaulted card is the real-world asset and the index sits on top of it. That is the full RWA claim: a new class of RWA on Solana, tradable indexes on physical collectibles.

The price that was missing

The data needed to price a whole category from real sales has been piling up for years, on Card Ladder and, since 2023, in public on Polygon, and until now it was read one card at a time.

Quanta reads it as a category, which is why the timing matters. In late 2025 the on-chain tape ran at about 10,000 trades a day, not 50,000 (Privy, Aug 2026). Today the indexes are published openly on the Quanta board for anyone to check, and the first market, PKMN, trades on the DEX at /trade/PKMN. Once a category's price is tradable, the hobby stops being a set of arguments about single cards and gets a market of its own.

What came before is on A world first. The mechanism is on How Quanta works. The venue is on The DEX.
