Amazon stock surged more than 7% in after-hours trading on July 30 after the e-commerce and cloud giant posted a second-quarter earnings beat that crushed analyst expectations across both earnings and revenue, driven by accelerating growth in its AWS cloud division. The company reported earnings per share of $5.75, towering above consensus estimates of $1.82—a 215% beat—while total revenue reached $200.6 billion, exceeding expectations by roughly $3.6 billion.
AWS, Amazon’s profit engine, posted its fastest quarterly growth in more than four years, with revenue surging 37% year-over-year to $42.2 billion. The acceleration marked the division’s strongest pace since the fourth quarter of 2021, when it expanded 40%, and reflected surging demand for AI infrastructure and cloud services. Amazon noted that its AI and chips businesses each exceeded $25 billion in annualized revenue run rates, with triple-digit percentage growth year-over-year.
Operating income jumped 43% year-over-year to $27.5 billion, underscoring the profitability gains flowing from AWS’s accelerating cloud business. AWS operating income alone rose to $16.6 billion in the quarter from $10.2 billion a year earlier, reflecting both revenue growth and operational leverage.
The strong quarter reflected sustained demand from enterprise customers and AI-focused partners. Anthropic, the AI startup in which Amazon has invested up to $25 billion, committed to spending more than $100 billion on AWS infrastructure over the next decade, securing up to 5 gigawatts of new capacity to train and run its models. This partnership has anchored AWS’s AI expansion, with the division’s AI business representing a growing share of overall revenue as customers race to build and deploy large language models and AI agents.
AWS’s acceleration from Q1’s 28% growth to Q2’s 37% reflects the easing of AI chip supply constraints and rising enterprise adoption of cloud-based AI services. The company’s Bedrock platform and custom Trainium and Inferentia chips have become central to its AI strategy, allowing customers to reduce dependence on third-party accelerators while building on AWS infrastructure.
The strong results prompted Amazon to raise its full-year 2026 capital expenditure guidance to $220 billion, up from the $200 billion it had projected earlier. CEO Andy Jassy attributed the $20 billion increase to higher memory chip costs but emphasized that even at the elevated spending level, the company will not have sufficient capacity to meet all the demand it faces this year. This signals that cloud and AI infrastructure investment will remain a strategic priority as Amazon competes with Microsoft and Google for enterprise AI workloads.
The earnings beat comes as the cloud infrastructure market remains intensely competitive. Microsoft stock surged 8% after beating Q4 earnings expectations, powered by strong growth in its Azure cloud business. When comparable tech earnings beats have driven stock rallies this earnings season, investors have rewarded companies that demonstrate both profitability gains and strategic positioning in AI infrastructure—a pattern Amazon’s results exemplify.
AWS’s 37% expansion underscores Amazon’s ability to scale its AI and chips operations while maintaining profitability in a competitive market. The company’s strong Q2 performance signals that enterprise demand for cloud-based AI services remains robust despite earlier market concerns about capital intensity and slowing cloud growth.
