Amazon has already been in the crosshairs of the White House when it comes to threats of antitrust investigations, and while some say this is simply Trumpian bluster that has a slim chance of going anywhere, some new numbers out from the researchers at eMarketer could prove to be a fan to the flames.

Amazon is set to clear $258.22 billion in US retail sales in 2018, according to eMarketer’s figures, which will work out to 49.1 percent of all online retail spend in the country, and 5 percent of all retail sales.
