JKIndex is building prediction markets for trading card game (TCG) grading outcomes, specifically targeting the 14M+ card PSA grading backlog.

Users predict what grade a card will receive before official results using practice tokens ($JKB with no cash value).

Recently launched with Superteam backing, very early account (<1 month old, <2k followers), working beta product live at jkindex.io with 'Before the Slab' practice markets.

Green flags: Working beta product deployed with functional prediction market interface · Clear real-world use case addressing 14M card PSA grading backlog · Backed by Superteam, lending credibility to early-stage project · Very early stage (account created Nov 2025, <2k followers) with genuine product traction · Novel market vertical combining prediction markets with TCG collecting community

Red flags: Practice tokens explicitly have no cash value, unclear path to real economic model · Extremely new account (created Nov 2025), limited track record · No token launch mentioned, monetization strategy unclear · Niche market (TCG grading) may limit scaling potential
