Amazon Increases AI Spending to $220 Billion Amid AWS Growth

Amazon.com, Inc. led a post-earnings rally among the Magnificent Seven stocks in August 2026, driven by the performance of its cloud computing subsidiary, Amazon Web Services. AWS reported year-over-year segment growth of 24-25%, fueled by AI infrastructure and custom silicon, and contributed more than half of the company's total operating income.

To capture further infrastructure demand, the company is increasing its AI infrastructure capital expenditure to $220 billion and embedding engineers directly with clients. This shift toward custom silicon positions the company as a potential competitor to Nvidia, though it remains exposed to cyclical risks if AI demand declines.

Despite the cloud success, the company faces headwinds in its marketplace revenue, which accounts for over 65% of total revenue. Energy volatility, inflation, and job losses have softened overall net sales growth to 6% year-over-year.
