StockX

What StockX does

StockX is a Detroit-headquartered online marketplace founded in 2015 that pioneered the 'stock market of things' model, applying real-time, supply-and-demand-driven pricing to the resale of consumer goods. The platform facilitates buying and selling across sneakers, apparel, accessories, collectibles, trading cards, and electronics in over 200 countries, with more than 60 million cumulative trades and 30+ million unique monthly visitors. Its core technology includes real-time marketplace pricing, proprietary multi-step authentication for product verification, and computer vision applied to authentication workflows and to the AI-powered photo analysis in the new Listings Marketplace (launched June 2026) for used sneakers and vintage apparel.

The company operates two marketplace formats: the Verified Marketplace for new/unworn items and the Listings Marketplace for used and unique items. Adjacent product lines include StockX Auctions (premium bidding on rare collectibles, launched November 2025), StockX Live (real-time social commerce launching Summer 2026), StockX Pro (tools for professional and high-volume sellers), and Store at StockX (inventory stored at StockX verification centers without physical possession). The platform is accessible via web, iOS and Android apps, and a permanent NYC SoHo retail location that reopened in June 2026 as a content studio and activation hub.

StockX generates revenue through marketplace transaction fees (take rates) on each sale, with strategic new segments launched at zero seller fees (Listings, June 2026) to drive adoption. Distribution extends beyond the proprietary platform through a Walmart Marketplace channel partnership (October 2024) and a Shopify Smart Matching integration (June 2025). In November 2025, StockX entered a partnership with CFTC-regulated prediction market exchange Kalshi to monetize aggregated transaction data via event contracts tied to product resale outcomes, and in April 2025 the company was reported to be in merger talks with South Korea-based resale unicorn Kream.
