Two-sided market
A two-sided market, also known as a two-sided network or two-sided platform, is an intermediary economic platform that connects two distinct user groups and creates value by enabling interactions between them. Each group provides the other with network benefits, making the platform more valuable as participation grows.
An organization that generates value primarily by facilitating direct interactions between two or more distinct types of customers is referred to as a multi-sided platform. Examples include credit card networks that link consumers and merchants, online marketplaces such as eBay that connect buyers and sellers, and digital platforms like Google or Facebook that connect users with advertisers.
The concept of two-sided markets has been developed extensively in the economics literature, particularly through the work of French economists Jean-Charles Rochet and Jean Tirole, as well as American scholars Geoffrey G. Parker and Marshall Van Alstyne. Their research formalized how pricing, platform governance, and cross-group externalities shape competition and business strategy in multi-sided industries.
Two-sided networks can be found in many industries, sharing the space with traditional product and service offerings. Example markets include credit cards (composed of cardholders and merchants); health maintenance organizations (patients and doctors); operating systems (end-users and developers); yellow pages (advertisers and consumers); video-game consoles (gamers and game developers); recruitment sites (job seekers and recruiters); search engines (advertisers and users); and communication networks, such as the Internet. Examples of well known companies employing two-sided markets include such organizations as American Express (credit cards), eBay (marketplace), Taobao (marketplace in China), Facebook (social medium), LinkedIn (professional media), Mall of America (shopping mall), Match.com (dating platform), AIESEC (leadership development for youth by placing talent in companies), Monster.com (recruitment platform), and Sony (game consoles).
Benefits to each group demand economies of scale. Consumers, for example, prefer credit cards honored by more merchants, while merchants prefer cards carried by more consumers. Two-sided markets are particularly useful for analyzing the chicken-and-egg problem of standards battles, such as the competition between VHS and Beta. They are also useful in explaining many free pricing or "freemium" strategies where one user group gets free use of the platform in order to attract the other user group.
