Beyond cards

Every page in this section talks about cards, because cards are where the sales are. The method itself never asked for cards. Sneaker collectors follow a deadstock pair to its last sale and have no number for sneakers as a market; watch collectors do the same with a steel sports reference. That is the gap graded cards used to have, and the engine that closed it for cards closes it for any category whose sales settle in public.

One input, any category

The engine described in Methodology principles asks for nothing specific to a trading card. It needs authenticated, graded items, a vault where each item is a token bound to its identity, and sales that settle on-chain as public records with a price, a timestamp and both parties. Given that record, the same engine selects by liquidity, takes medians, removes trades that look like manipulation, scales, reviews and publishes. Nothing in the code path knows whether the item is a card.

That is why a new category is a configuration row rather than a project, as The index family explains, and why the direction of the family is already clear.

Where the family extends

Past cards, the family keeps the same shape. The number in a ticker hints at its constituent count.

Ticker	Category	What it tracks
NKE50	Nike sneakers	Authenticated, graded pairs, around fifty models
RLX20	Rolex watches	Authenticated references with box and papers, around twenty
CMX25	Graded comics	Slabbed issues across publishers, around twenty-five, at specific grades
VGS30	Sealed video games	Graded sealed cartridges and discs, around thirty titles

What a category needs

Each of the three requirements protects the index in a specific way.

Authentication and grading come first, because a category price only means something when two items are interchangeable. A raw sneaker and a pair sealed by a grader are not the same object. A market that agrees on a grade has constituents to price; without that agreement there are only items with stories.

Vault custody with on-chain settlement comes second, because a price has to be a fact. A listing is an ask, and a dealer's quote is an opinion. A sale that settles on-chain, for a vaulted item bound to its token, is a record anyone can verify, the same standard The data source holds cards to.

Enough trades across enough participants comes third, because medians need a sample and manipulation guards need a population. A trophy watch that changes hands twice a year produces no price, however famous it is, and a category where five wallets do most of the trading gives the guards nothing to compare against. Depth is measured, not decided.

Where each vertical stands

Comics are the closest. The largest on-chain vault for graded cards accepts graded comics as well (one vaulting venue, Sep 2026). It added them in June 2025 (CGC, Jun 2025), and by mid-2025 they made up 22%+ of the business by revenue (Forerunner Ventures, Jul 2025). Grading standard, vault and on-chain settlement are all in place, and the venue's public listings showed about 4,100 comics among more than 375,000 items in total (one vaulting venue's public listings, 15 Sep 2026). That record is what CMX25 reads.

Watches have the authentication in place. The same venue began offering luxury watches in February 2026, each in unworn or mint condition with box and papers (one vaulting venue, Feb 2026), and its listings held 20 watches on 15 Sep 2026. Data-only watch indexes already track the market (WatchCharts Overall Market Index, Chrono24 ChronoPulse, Sep 2026). RLX20 brings the on-chain method to it, built from vaulted sales that settle in public.

Sneakers opened for pre-registration on the same venue (one vaulting venue, 14 Sep 2026), the first step toward the vaulted sales record NKE50 tracks.

Sealed video games and wine follow the same path. When a venue gives a category the shape cards have, a vault, a token per item and settlement on-chain, the method applies unchanged.

Cards first

Cards have the deepest on-chain record of any physical collectible. More than 375,000 items were listed on the largest on-chain vault for graded cards, about 68% of them Pokémon (one vaulting venue's public listings, 15 Sep 2026). Daily activity there grew from roughly 10,000 trades a day in late 2025 to more than 50,000 on many days in 2026 (Privy, Aug 2026), and the average card trades 8 times per month (Forerunner Ventures, Jul 2025). Cards show all three requirements at once, at scale, which is why the Quanta board carries 44 collectible indexes today.

So the order is not a matter of taste. The method extends to any physical collectible whose authenticated items are vaulted and whose sales settle on-chain. Once a category's sales settle on-chain in enough volume, it is measured; when it clears the gate, it is published; when demand is there, it gets a market. That path is the last stage of the Roadmap, paced by the data.

The first index, and the template every later one follows, is PKMN.
