They’re usually the first to notice when a card starts to matter.
Looking for a few who want to help build what comes next.

We talk JK Index, the market intelligence layer for TCGs:
🔸 why TCG pricing is fragmented (Pokémon/One Piece/Riftbound)
🔸 building the truth layer

@Polymarket style prediction markets for raw to graded cards.
Not generic sports lines.
Not tokenized gacha.
Actual collector uncertainty:
What will this raw card grade?
JK Index is uniquely positioned here because we have already built the card data, | @JKIndex_ ✓ | 1.7K | 4.7K | 2.8x | 48 | May 1 |
| 8 | [video] PSA launching a backlog tracker is good transparency.
But a 14M card active queue makes one thing obvious:
The “before the slab” window is a real market.
Collectors need a way to price grade uncertainty before the card comes back.
Guess the grade.
Back your conviction.

| 12 | [image] Building new market primitives is hard.
But this one does not start from zero.
Collectors already get the behavior.
Every raw card has a number in your head before it ever leaves for grading.
Grading volume keeps climbing.

You can come to the platform, research cards, track markets, build a portfolio, and leave without spending a cent.
That is intentional.

Pokémon moves billions yearly.
One Piece is expanding worldwide.
Riftbound is backed by one of gaming’s largest IPs.
This isn’t hypothetical.
Real collectors. Real volume.
We’re building the data layer they deserve, and later, the marketplace.

Back on Feb 12, we wrote about the JK Index money layer.
We wanted to answer the question: How will the JK Index make money?
The interesting part now is that pieces of that model are starting to move from theory into reality.

| 19 | [image] You can make your first raw to graded prediction today.
It’s free. Costs $0.
But it helps us test something much bigger:
Can collectors form a public read before a card comes back from PSA?

A lot of cold outreach.
A lot of trying to get closer to the people already living around grading speculation every day.

I’ve been building on Solana since 2021.
But this past year, I started building in a market I actually care about:
TCGs and raw cards before grading.
Collectors already speculate before they submit.
In Discords.

A big brand can get...

But it cannot force people to care about a loop that does not hold up on its own.
TCG collectors already have the behavior, they...

This is a big step toward opening the Index up to other builders!
The contract is clear, so integrations are predictable now.

| 31 | [text] The best collector products won’t be built by people who don’t collect.
JK Index is entering a growth phase around Before the Slab, and we’re looking for collector operators who understand raw cards, grading, condition, comps, and the chaos of this hobby.

That is the line.
And it is why I think new market primitives need to be built with restraint.
With something new like TCG grading prediction markets, clarity has to come first.
