The division's operating profit, meanwhile, grew 77% over the same time period to $US2.1 billion, accounting for more than a third of Amazon's total net profit for the period.
"When the stocks that are carrying the markets begin to crack, investors are going take cover".
To be sure, Amazon shares (AMZN.O) dropped by the most in four years on Friday after its outlook for holiday season sales missed targets, fanning concerns that Wall Street's tech darlings are finally starting to face stronger competition, Reuters reported.
Meanwhile, Amazon Web Services continued to grow at a rapid clip, now pushing a run rate of $27 billion.
But the company tempered that standout result with several pieces of disappointing news.
Analysts have been watching the company's AWS cloud services business, and Amazon met, but did not beat Wall Street estimates, reporting revenues of $6.7 billion. Analysts projected $US3.9 billion.
Investors focused on the negative.
Q3 revenue: $56.6 billion. Analysts were looking for $US57.1 billion.
Revenue from Amazon's global business, which brings in 27.5 per cent of total sales, was at the heart of the shortfall in results, growth halving to 13.4 per cent compared to the previous quarter. Analysts had forecast $3.11 per share. Specifically, they were hoping for numbers between $66.5bn (£51bn) and $72.5bn (£56bn).
The nerve-wracking anxiety that's gripped the USA stock market seems oddly unmoored from economic reality: Despite the turbulence on Wall Street, economic growth is strong, unemployment ultra-low and consumers exceptionally confident. It purchased online pharmacy PillPack in June, which followed its US$13.7 billion acquisition of Whole Foods a year ago to jump start its grocery business. But its outlook implies a profit of between $3 a share and $5.54 a share, assuming its interest income, interest expense, tax rate, and share count remain about the same.
Shares in Alphabet fell about 6 per cent, knocking about $45 billion off its market value after it fell short on sales after beating estimates for the past eight quarters.
Yet again, Amazon's cloud business gave it a big boost. That division saw sales jump 35% to $34.3 billion.
Operating income is expected to be between $2.1 billion and $3.6 billion, compared with $2.1 billion in fourth quarter 2017. Add in the recent stock market rout, and the tech companies had little room to bobble their results.
Sales increased 29.33 percent from the third quarter of 2017.
Amazon Business has also recently launched new Business Prime benefits in the US, Germany and Japan. In its "other" category, which is mostly made up of its growing advertising business, revenue more than doubled to $2.5 billion.
As of this writing, Amazon shares are rising almost 7% to $1,783.
