Amazon raised its 2026 capital expenditure forecast to $220 billion after reporting strong cloud growth in the second quarter, signaling the company’s aggressive bet on artificial intelligence infrastructure is paying off. The $20 billion increase from the previous $200 billion projection reflects higher memory costs as the company scales data centers to meet surging demand for AWS services.
AWS revenue surged 37% year-over-year to $42.2 billion in Q2 2026, marking the cloud division’s fastest growth in 18 quarters and outpacing analyst expectations of 31% growth. Amazon’s total second-quarter revenue reached $200.6 billion, up 20% from the prior year, delivering what the company described as its first $200 billion quarter.
CEO Andy Jassy acknowledged on the earnings call that despite the massive capex commitment, Amazon still won’t “have enough capacity to meet all the demand” for AI infrastructure through 2027. The capacity constraint underscores how rapidly cloud demand is outpacing even record-level infrastructure spending across the industry.
The capex increase comes as Amazon and its peers in the hyperscaler race are locked in competition for dominance in AI cloud services. Alphabet raised its 2026 capex forecast to $205 billion after Q2 earnings beat, and Microsoft and Meta have similarly announced substantial increases in data center spending. Combined, the four largest tech companies are projected to spend over $700 billion on AI and cloud infrastructure in 2026.
Amazon’s willingness to raise capex guidance despite the massive increase signals confidence that AWS revenue growth will justify the investment. Operating income rose 43% to $27.5 billion in the quarter, and AWS operating margins reached 39.4%, demonstrating that the company’s cloud business is generating the profit needed to fund its infrastructure expansion. The strong earnings beat fueled Amazon stock surge on Q2 earnings and AWS cloud growth, with shares climbing in after-hours trading on July 30.
The memory cost inflation driving the capex increase reflects broader supply constraints in AI chip markets. Demand for high-bandwidth memory and other specialized semiconductor components has outpaced supply, pushing up the cost of building AI-capable data centers. Analysts note that if memory costs remain elevated, Amazon and other hyperscalers may need to raise capex guidance further in coming quarters.
Amazon’s infrastructure spending has become central to investor sentiment around the stock. Earlier guidance of $200 billion in capex had generated concern about cash flow and profitability, but the strong AWS growth and margin expansion have reassured markets that the company is deploying capital efficiently. AWS growth of 37% and capex raised to $220B demonstrated that cloud revenue acceleration is outpacing the pace of capex increases, a key metric for evaluating whether the AI infrastructure investment will generate returns.
