Why Amazon Has No Real Western Rivals in E-Commerce
BBC Business reported Saturday that Amazon’s grip on Western online retail has grown so vast that no single competitor comes close to threatening its position, with experts pointing to a decades-long strategy built on patience, reinvestment, and deliberate platform expansion.
A Market Share Gap That Keeps Growing
Amazon captures roughly 40.5% of all US online retail sales. Its nearest domestic rival, Walmart, accounts for just 9.2%. eBay trails at around 3%. In the United Kingdom, Amazon holds approximately 30% of the online retail market. Those figures come from data cited last month. The gap is not closing.
The company also recently surpassed Walmart to become the world’s largest business by annual revenue — a milestone that underscores just how far it has travelled from its origins as a garage-based bookseller founded by Jeff Bezos in 1995.
Why Rivals Could Never Keep Up
Experts point to several interlocking advantages that compounded over time. First was timing. Amazon moved early and scaled fast, capturing customer habits before traditional retailers understood what the internet would become.
Equally significant was financial patience. For years, shareholders tolerated losses while Amazon reinvested aggressively rather than paying dividends. David Yoffie, professor emeritus at Harvard Business School, told BBC Business that pursuing the same approach would have crushed the stock prices of traditional retailers and alienated their shareholders immediately.
Today Amazon cross-subsidises its lower-margin retail arm using profits generated by Amazon Web Services, its cloud-computing division and primary earnings engine.
The Platform Shift That Changed Everything
Annabelle Gawer, director of the Centre of Digital Economy at the University of Surrey, described Amazon as the dominant firm in e-commerce — one whose product breadth remains unmatched. A key turning point came in 2000 when Amazon opened its store to third-party sellers. The resulting network effect meant more sellers attracted more customers, and more customers attracted still more sellers. Breaking that loop proved nearly impossible for new entrants.
The 2005 US launch of Amazon Prime — and its 2007 UK rollout — added another layer of lock-in. Annual subscribers received fast, free delivery and had little reason to shop elsewhere.
Background — From Bookstore to Global Behemoth
Amazon’s expansion into cloud computing, consumer hardware, original video content, groceries via Whole Foods, and even healthcare illustrates a culture of experimentation described by Sunil Gupta, also a Harvard Business School professor. The company enters new sectors, tests aggressively, and exits when initiatives fail — a cycle most traditional retailers cannot afford to replicate at scale.
Chinese platforms Temu and Shein have carved out space at the ultra-discount end of the market. But no Western business has assembled the same combination of logistics, data infrastructure, third-party marketplace scale, and subscription loyalty that defines Amazon today.
