Amazon has ~35% of US ecommerce and ~6% of addressable US retail, and is two thirds the size of Walmart, which would make an antitrust case against it difficult (Benedict Evans)

Benedict Evans:
Amazon has ~35% of US ecommerce and ~6% of addressable US retail, and is two thirds the size of Walmart, which would make an antitrust case against it difficult  —  - Amazon is a big company, but what does that mean?  How big is ‘big’?  What does ‘dominant’ or ‘scale’ or ‘huge’ mean when US retail is $6 trillion a year?
