[video] Creators are going to shape the future of collecting just as much as marketplaces. 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. DMs open 📥

[video] Markets down. Still building. 👑🧱 On the Mod Media Pump fun Build in Public podcast 🎙️👇 We talk JK Index, the market intelligence layer for TCGs: 🔸 why TCG pricing is fragmented (Pokémon/One Piece/Riftbound) 🔸 building the truth layer 🔸 Pricing API v0 for builders

[image] Before the Slab. @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,

[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. Let the

[image] Slowly but surely. 👑🧱 Excited to lock in our first partner & real use case for the JK Index Pricing API: powering buy/sell/trade lists for card shows with pricing + confidence. v0 slated for a March release. This is the whole thesis: truth layer → partners → distribution.

[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. The missing piece is market structure around the

[image] JUST IN: Collectors now give @Groovy_HQ ’s Mega Charizard Y ex an 83.3% chance of grading a PSA 9.

[video] Yes, we are looking for growth operators! The catch? You have to be passionate about TCGs. DMs are open 📩

[text] Everything about the Index is meant to be additive to a collector’s workflow. You can come to the platform, research cards, track markets, build a portfolio, and leave without spending a cent. That is intentional. I did not go monetization first. I started with the hard

[image] Gpuff 🌞 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. Early. Not wrong. 🧱

[text] Gpuff! 🌞 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. Worth revisiting below 👇

[image] v0 TCG Pricing API docs are now live on the JK Index 👑 This is a big step toward opening the Index up to other builders! The contract is clear, so integrations are predictable now. Building a TCG app and want clean pricing data? DM me, I'm onboarding a few early partners. 🧱

[image] BTS ~1 week usage: 🔸 18 JKB accounts 🔸 17 starter grants claimed 🔸 43 fills 🔸 15 participants 🔸 1,255+ JKB simulated volume 🔸 29 fills in the last 7 days Collectors are onboarding, claiming practice capital, and placing positions without needing the more explained 🙌

[text] Gpuff! 🌞 Jumping on stream at 7 AM MDT to cover last weeks updates for Colosseum as well as what's next for JK Index Index Listings and the Marketplace 🎥 Link below 👇

[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. People who know the

[image] Oh...?

[video] Gpuff 🌞 A few of the most important updates shipped to the Index over the last few days: 🔸 16,755 Mega Evolution sales added to production 🔸 Scarlet & Violet 151 master set pricing restored 🔸 Edition leakage fixed for non-vintage Pokémon 🔸 Sale history + card stats brought

[text] Gpuff! 👑 Tomorrow we go live for the Colosseum Hackathon Kickoff livestream 📅 We’ll be sharing what we plan to ship all through April. Also: we applied to build in public at the Colosseum Build Station in San Francisco 🌆 Brick by brick. 🧱

[video] This is the bet. The first power users for Before the Slab will be collectors already guessing the grade every day.

[video] A lot of last week’s Before the Slab work was testing the spots where the system should stop. We hit guardrails. The flow refused to move forward. Some actions stayed blocked until the state was cleaner or the intent was more explicit. We failed closed as expected. With a new
