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.

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.
