CYKI — Sneaker Portfolio

Know what your collection is actually worth. CYKI is the sneaker portfolio tracker for collectors who want more than a shoebox full of receipts. Catalog every pair you own and watch its live resale value update daily. No spreadsheets, no guesswork. LIVE MARKET VALUES & P&L Every pair is priced against real resale market data, updated daily. See your total collection value, cost basis, and profit or loss at a glance — per pair or across your whole rack. THE CYKI 100 An independent daily index for the sneaker resale market — not run by a marketplace. Track how the market is actually moving, then see how your own collection stacks up against it. Beating the index is the flex worth screenshotting. PRICE ALERTS Set a target price on any pair and track it against the live market, so you know the moment your grail finally moves. No more checking five different apps. GRAILS & WATCHLIST Track the pairs you do not own yet. Keep a running watchlist of grails, and when you finally cop one, bring it straight into your collection. BEAT THE MARKET Pick a basket of five sneakers and compete against the CYKI 100 all season. Every two weeks a themed event rotates the challenge — Jordan only, under $200, Adidas, New Balance, and more — so there is always a new game running alongside the monthly season. Built by collectors, for collectors. Not investment advice — just an honest read on what's in your rack.
