Amazon (NASDAQ: AMZN) has delivered one of its strongest quarters in recent history, posting results that far exceeded analyst expectations. The stock surged the day following the earnings release. One division, in particular, stood out: Amazon Web Services (AWS), the segment most exposed to artificial intelligence.

AWS significantly outperformed forecasts, and the momentum may continue in the quarters ahead.

AWS Is the Primary Reason to Invest in Amazon

While many investors associate Amazon with its dominance in e-commerce, there are more compelling reasons to own the stock—chief among them being its AWS cloud computing service.

In Q2, AWS reported sales growth of 37%, crushing Wall Street's expectation of 31% growth. This is significant because AWS generates the majority of Amazon's profits.

• AWS generated $16.6 billion in operating income in Q2.
• That represents approximately 60% of Amazon's total operating income.
• Despite AWS accounting for only 21% of total revenue, its profit contribution is outsized.

This quarter's rapid growth is just the beginning. Amazon is investing heavily in capital expenditures this year—$220 billion—with nearly all of it directed toward building and equipping data centers. This expansion will increase the computing capacity available for clients, driving further revenue growth. Investors should recognize that this is the new paradigm: AWS—and Amazon as a whole—is likely to deliver exceptional growth for the foreseeable future, especially as AI demand continues to accelerate.

Companywide, Amazon's 20% revenue growth rate is among the best it has posted since the COVID-19 era.

As noted, this growth is expected to accelerate further, as AI spending shows no signs of slowing. All signs point to Amazon being a strong investment over the next several years, with AWS's expansion substantially boosting the company's profit and growth profile.

Amazon should outperform the broader market and deliver the market-beating returns investors seek. Even after the stock's post-earnings surge, this strength may continue, as few investors anticipated such a strong quarter from Amazon.
