SneakPrice turns the raw sneaker resale market into structured, queryable data: median prices, listing volume, market breadth, and indexes — all derived from live eBay sold and active listings and refreshed hourly. The snapshot below summarizes what is being tracked right now.
Every figure traces back to live eBay market activity — both sold comps and active listings. We aggregate per sneaker into a median market price and a listing count, then roll those up into SPX-* indexes. The pipeline captures fresh snapshots hourly.
What we measure
Per model: median resale price, the active listing count (a liquidity proxy), and price dispersion. Per segment: an index level, day-over-day change, and breadth — the share of constituents trading up. Together they describe both price and how reliable that price is.
Methodology and transparency
Medians (not averages) blunt the effect of outlier listings, and trimmed statistics reduce noise further. Where data is still accumulating, we show it honestly rather than fabricating a number — coverage expands as more history is captured.

Hourly. A capture job pulls fresh listing data and recomputes medians, indexes, and breadth.
Is the data real or simulated?
Real. All prices and volumes are derived from actual eBay marketplace listings; we do not fabricate underlying values.
