TLDR: Amazon Web Services (AWS) reported Q2 2025 revenue of $30.87 billion, surpassing Wall Street expectations. However, the cloud division’s operating income of $10.2 billion fell short of forecasts, and its 18% year-over-year growth lagged behind Microsoft Azure (39%) and Google Cloud (32%). This led to a 7.7% drop in Amazon’s stock, as investors weighed strong revenue against contracting profit margins and significant AI infrastructure investments.
Amazon Web Services (AWS), Amazon’s dominant cloud computing arm, announced its second-quarter 2025 financial results, revealing a revenue of $30.87 billion. This figure represents an 18% year-over-year increase, narrowly exceeding Wall Street’s expectations and reaffirming AWS’s leading position in the global cloud infrastructure market. Despite this robust top-line performance, the division’s operating income came in at $10.2 billion, falling short of the $10.9 billion consensus forecast.
The shortfall in operating income, coupled with a slower growth rate compared to its primary competitors, triggered a significant selloff in Amazon.com, Inc. ($AMZN) stock. Shares plummeted 7.7% during Friday trading, closing at $216.07, down from a previous close of $234.11.
While AWS maintains a substantial revenue base, its growth rate of 18% was notably outpaced by Microsoft Azure, which reported a 39% increase, and Google Cloud, which grew by 32%. This disparity highlights an increasingly competitive landscape, with rivals accelerating their growth, largely fueled by enterprise AI adoption and aggressive infrastructure buildouts.
One of the key factors impacting AWS’s profitability is the substantial investment in AI-related infrastructure. The capital-intensive nature of building and maintaining AI-ready data centers has begun to squeeze profit margins. AWS’s operating margin dropped to 32.9% in Q2, a decline from 39.5% in the previous quarter and 35.5% a year ago, marking its lowest level since the final quarter of 2023. Amazon disclosed capital expenditures exceeding $31 billion in Q2, a new record, with Chief Financial Officer Brian Olsavsky indicating that such investment would continue at a similar pace through the second half of the year. CEO Andy Jassy has committed to ramping up investments in AI infrastructure, signaling a long-term strategic focus on the space, even at the expense of short-term profit compression.
Amazon’s overall Q2 revenue rose 13% year-over-year to $167.7 billion, surpassing the average analyst estimate of around $162 billion. Net income increased by more than one-third to $18.2 billion. However, the company’s forecast for the third quarter, projecting operating income between $15.5 billion and $20.5 billion (with the lower end below Wall Street’s average expectation of $19.4 billion), further contributed to investor unease. Amazon also announced plans to open a new AWS region in Chile by 2027, underscoring its global expansion ambitions.

Despite the current challenges, Amazon management emphasized AWS’s continued position as the largest global cloud provider, noting that Azure, its closest rival, is approximately 65% of AWS’s size. They also highlighted AWS’s superior security, durability, latency, and throughput as key differentiators. The company introduced Alexa+ and Trainium 2 AI chips to boost cloud competitiveness, aiming to capitalize on a projected shift in IT spending to cloud over the next 10–15 years. CEO Andy Jassy acknowledged that demand for AI is currently outpacing AWS’s ability to scale, reinforcing the need for continued heavy investment in this area.
