Unstoppable Amazon turned in another strong quarter, leaving its rivals in the dust during the crucial holiday shopping season.
Revenue in the fourth quarter rose 38 percent, to $60.5 billion, while the Seattle behemoth reported record profits of $2 billion.
Amazon shares were up more than 6 percent, to $1,476, in after-hours trading.
Amazon Founder and Chief Executive Jeff Bezos, with the after-hours stock bump, saw his world-leading net worth jump to a staggering $128.6 billion.
Bezos said Alexa was one of the key drivers of the company’s success.
“Our projections for Alexa were very optimistic and we far exceeded them,” the CEO said in a statement. “We don’t see positive surprises of this magnitude very often — expect us to double down.”
Amazon’s results also beat Wall Street’s forecast for revenue of $59.83 billion.
Despite reports last year that Amazon Prime’s growth in the US may be hitting a wall, Amazon said that it gained more members in 2017 — in both the US and worldwide — than in any other year.
