We estimate that US Amazon retail ecommerce sales reached $187.94 billion in 2018, per our May 2019 forecast. While Amazon wouldn’t provide a precise number of sellers, a spokesperson said the marketplace has hundreds of thousands of sellers listing hundreds of millions of products.
Most retail ecommerce transactions still take place on PCs—we forecast that retail mcommerce sales will account for more than half (53.7%) of retail ecommerce sales beginning in 2021. Amazon and the Duopoly. Despite becoming the No. 2 search ad seller in the US, Amazon doesn’t appear to be disrupting the digital ad duopoly as some industry observers may have expected (or merely hoped).
This year, we’ll see double-digit growth in retail ecommerce sales—a rise of 10.9% will see sales total £106.46 billion ($141.93 billion) and account for 22.3% of total retail. It’s because of this “digitalness” of UK consumers when it comes to shopping that digital ad spend is seeing such strong numbers.
