Amazon Shares Jump as AWS Growth Accelerates, Easing AI Spending Concerns

Amazon.com Inc. (AMZN) reported that revenue growth at its cloud computing unit significantly outpaced market estimates for the second quarter, providing a strong signal that its heavy investments in artificial intelligence are yielding returns. The news sent the company's shares up by as much as 9% in after-hours trading.

AWS Powers Quarterly Beat

The company's cloud division, Amazon Web Services (AWS), was the standout performer in the quarterly results.

• AWS revenue jumped 37% to $42.2 billion for the quarter ended June 30.
• This growth rate easily surpassed the consensus analyst estimate of a 31.21% increase, according to data from LSEG.
• CEO Andy Jassy noted in a statement that it was the unit's fastest growth in 18 quarters, adding, "Our AI and chips businesses each eclipsed run rates of more than $25 billion."

Market Impact and Spending Context

The strong AWS performance appeared to reassure investors who had been concerned about the massive capital expenditures required for AI development across the tech sector. The results mirror solid cloud reports from rivals Microsoft and Alphabet, suggesting broad-based demand for AI infrastructure.

Despite the revenue strength, Amazon's free cash flow on a trailing 12-month basis was negative $7.6 billion, a sharp reversal from a positive $18.2 billion a year earlier. This reflects the intense spending on data centers, a trend seen across Big Tech. "There were concerns about market share losses on AWS, but that’s been put to bed now," said Dan Morgan, portfolio manager at Synovus Trust, quoted by Reuters. "The AI tide is rising all boats here."

Other Business Segments Show Strength

Amazon's other key business lines also demonstrated robust growth. The company's advertising sales, a closely watched metric, rose 26% from the prior year to $19.8 billion.

The e-commerce giant's retail operations benefited from its annual Prime Day shopping event, held from June 23-26. An estimate from Adobe Analytics cited by the source pegged total spending during the event at over $26.4 billion.
