eBay

eBay began as an online auction service and developed into a marketplace rather than a conventional retailer. Pierre Omidyar launched AuctionWeb in September 1995, initially allowing users to list objects and compete for them through timed bidding; the company adopted the eBay name in 1997.¹ Unlike an inventory-based retailer, eBay generally does not own the goods listed on its platform. Its marketplace model supplies listing, search, payment, communication, and transaction services while sellers set prices and fulfill orders.

The platform earns revenue principally from seller fees and payment-related services, with rates and features varying by category, seller status, location, and transaction type.² This structure gives eBay unusually broad inventory, including one-off, collectible, refurbished, and secondhand items, but it also makes trust, accurate descriptions, and dispute resolution central to the business.

eBay combines auction listings with fixed-price sales, allowing the same marketplace to serve both price-discovery and ordinary retail transactions. Sellers create listings with descriptions, photographs, shipping terms, and return conditions; buyers can search, filter, compare, bid, or purchase immediately when a fixed price is offered.² Search ranking and seller-performance standards affect how prominently listings appear, while feedback and transaction records provide signals about reliability.

Its inventory ranges from consumer electronics and clothing to vehicle parts, industrial equipment, watches, trading cards, and antiques. Specialized authentication programs have been introduced for selected high-value categories, including eligible sneakers, handbags, watches, and trading cards, where inspection can reduce counterfeit and condition risks.³ Payments, shipping labels, returns, and buyer protection are increasingly integrated, although the exact protections depend on the transaction and jurisdiction.

eBay expanded from auctions into a broad international marketplace through category growth, acquisitions, and localized sites. The company purchased PayPal in 2002, making the payment service a major part of its commerce ecosystem, but PayPal became an independent public company in 2015 after the businesses were separated.¹ eBay has also bought and sold businesses as it concentrated on its core marketplace, including the 2020 sale of StubHub and the 2021 sale of Classifieds Group to Adevinta.⁴

International operations expose the marketplace to different tax rules, consumer-protection laws, customs systems, currencies, and delivery networks. The company therefore operates through regional websites and services rather than treating cross-border commerce as a single uniform market. Its global reach is valuable for niche goods because a seller can find distant demand that may not exist in a local market.

eBay’s early reputation system was a significant experiment in online trust: buyers and sellers could publicly rate one another after transactions, creating a visible history in a setting where participants often had no prior relationship.⁵ The system later became more structured, with separate seller-performance measures and formal protections, because feedback alone could not address fraud, disputed descriptions, or delivery problems.

The marketplace also supports specialist forms of commerce that receive less attention than consumer electronics or fashion. Collectors use it for coins, stamps, comics, toys, and trading cards; mechanics and restorers search for discontinued parts; and small merchants use it to reach international buyers without operating a standalone store. At the same time, eBay maintains intellectual-property reporting and removal procedures, including its Verified Rights Owner program, to address allegedly infringing listings.⁶ These edge cases illustrate both the breadth of its inventory and the regulatory complexity of an open marketplace.
