58% of global e-commerce is concentrated in just six companies. And just four Chinese companies account for almost half of global digital sales.

Global e-commerce reached $3.4 trillion last year, according to a new report from Activate Consulting.

• Amazon: 13%

• JD.com: 9%

• Pinduoduo: 4%

• eBay: 3%
