Amazon is coming for couriers.

The Seattle tech giant is now delivering 50 percent of packages itself, according to Morgan Stanley estimates spotted by CNBC. Analysts estimate Amazon Logistics will soon overtake UPS and FedEx in the total volume of packages delivered in the U.S.

Update: Amazon confirmed it is now delivery “approximately half” of its packages to Bloomberg. Amazon’s worldwide operations chief, Dave Clark, said the company has delivered 3.3 billion packages worldwide this year. 

Amazon’s package deliveries are largely “focused on urban areas” according to Morgan Stanley. The retailer still relies on third-party couriers for many of its last-mile deliveries in rural regions. Amazon is now shipping about 2.5 billion packages per year and has more than doubled its share of U.S. package volumes since this time last year, according to the report.

Amazon is spending billions on its growing shipping operations business. The company listed “transportation and logistics services” as a business where it is battling competitors in its annual 10-K filing from last year.
