New & Refreshed Listing Activity — Trailing 30-Day Snapshot (2026-07-25 – 2026-08-24)
About this report: This is a rolling 30-day snapshot of recent listing activity — the unique part numbers and the sellers that uploaded or refreshed inventory during the window. It is NOT a count of total marketplace inventory or of the full seller community; for scale, the PartsBase community carries well over 90 million live line items from thousands of sellers across 200+ countries, and the suppliers cited below are the subset active in this 30-day window. Because the figures depend on which sellers uploaded during the window, every metric — including period-over-period changes — describes recent activity and its composition, not the size or growth of the marketplace.
Executive Summary
During the trailing 30-day window ending 2026-08-24, N active suppliers uploaded or refreshed listings covering M unique part numbers across K countries. These figures describe the parts and sellers active in this window — a subset of the full PartsBase community — and are not a measure of total marketplace inventory. When you give the period-over-period changes, say in the same sentence that swings of that size between two 30-day windows typically reflect the timing of a few large catalog uploads rather than any change in the size of the marketplace. The most significant anomaly or market signal from the analytics data is...

Data Sources & Methodology
This report analyzes a 30-day rolling upload cohort from the PartsBase Global Marketplace, published weekly. Each edition counts only the listings that suppliers uploaded or refreshed between the reporting window dates shown above; listings not re-uploaded during that window are excluded. These figures therefore describe supplier activity within the window rather than the full PartsBase catalog, which is substantially larger. Because a 30-day window is re-cut every week, consecutive editions overlap by about three weeks. Note also that unique-part-number counts are not directly comparable to marketplace-wide 'line item' totals, which count each seller's listing of a part separately. Period-over-period comparisons measure the change between two consecutive upload windows and can move sharply when a large supplier performs a bulk catalog refresh. Metrics use unique part number and supplier counts rather than raw listing volume.
