Amazon has a 14% share of the global retail market, as well as accounting for over 50% of all retail sales in the US. However, based on current trends Amazon could surpass the world's largest retailer Walmart soon. It's thought that Amazon's sales are vastly underestimated, due to the fact that products sold by third-party sellers are only recorded in terms of the commission, fulfilment and shipping fees. According to one analyst, this would mean that the value of all services and products traded on Amazon was around $600 billion (£460bn) in 2019. Amazon hit headlines in February this year when it gained a $1 trillion (£766bn) valuation. It's actually the fourth company to do so: Apple hit the landmark in August 2018 while Microsoft reached it last year and Alphabet, Google's parent company, did so in January. At the time of writing (10 November), Amazon is valued at $1.58 trillion (£1.2tn).
