StockX

StockX is an online marketplace and data analytics platform that operates as a "stock market of things," focusing on authenticating and selling sneakers, streetwear, electronics, trading cards, and other collectibles.

Founded in 2015 by Josh Luber (Campless) and Greg Rosen, StockX rebranded as StockX in 2016 and grew into a global marketplace. The company is headquartered in Detroit, Michigan, and has developed a worldwide presence with various authentication operations.

The platform uses a live bid/ask system where buyers place bids and sellers place asks, with matches resulting in sales at the current price. Price history, trading volume, and volatility data are displayed for each product variant, enabling price discovery and trend analysis.

Sellers list items for sale and buyers bid for them; once a sale is executed, the item is shipped to StockX's authentication centers where it is inspected for authenticity and condition, and only after authentication is the item shipped to the buyer. If an item fails authentication, it is returned to the seller or refunded.

StockX charges transaction-based fees to buyers and sellers, plus applicable shipping costs for authentication. Fees vary by seller status, volume, and other factors.

The company provides services in multiple regions and currencies, expanding beyond sneakers to include streetwear, electronics, trading cards, and collectibles. In addition to marketplace functions, StockX offers historical price data and market analytics to users for research and valuation purposes.

StockX has attracted venture funding from investors and private equity firms as it has grown into a major player in sneaker and streetwear markets, emphasizing price transparency and authentication.
