Figure 1 eBay Porter’s Five Forces
Threat of substitute products or services for each type of service offered by eBay is significant. eBay services can be divided into three categories: Marketplace, StubHub and Classified.
A great range of supermarket chains such as Wal-Mart, Tesco, Target, Sainsbury’s and others represent a significant substitution for eBay Marketplace. Moreover, the presence of e-commerce sites of all large supermarket chains further increases the significance of this threat.
eBay StubHub is a online place where customers can buy and sell tickets for sports, concerts, theatre and other live entertainment events. Substitute services for StubHub include, but not limited to offline ticket offices, online forums and websites selling tickets along with other types of products and services.
For eBay Classifieds, substitute services relate to Yellow Pages and other similar print advertising mediums. Media advertising, as well as, advertising on a wide range of media platforms can also be mentioned as substitutes for eBay Classifieds.
Rivalry among existing firms in industries where eBay operates is highly intensive. This is primarily due to the impressive rate of industry growth and increasing numbers of competitors operating in the industry.
eBay competes with a wide range of retailers, distributors, liquidators, import and export companies, auctioneers, catalogue and mail order companies, classifieds, directories, search engines, commerce participants (consumer-to-consumer, business-to-consumer and business-to-business), shopping channels and networks.
eBay’s major competitors include Amazon Inc., Alphabet Inc, Alibaba, Yahoo Inc., Best Buy Co. Inc., Target Corporation, Chemours Co., Family Dollar Stores Inc., Staples Inc., Priceline Group Inc. and others.
As it is illustrated in Figure 2 below, the number of eBay active users has been consistently growing during the last six years. This is a clear indication of eBay’s share growing in respective markets in the global scale.
