Amazon rises as AWS growth alleviates concerns regarding its AI expenditures.

      Shares of Amazon surged over 12% after its cloud division recorded its fastest growth in more than four years, alleviating investor concerns that the company's increasing AI expenditures were outpacing returns. Amazon Web Services (AWS) experienced a 37% growth in the second quarter, significantly surpassing the approximately 31% forecasted by analysts, adding around $300 billion to Amazon's market value prior to the market opening.

      This marks a notable contrast to the previous quarter when a one-time gain from Anthropic inflated the figures while free cash flow plummeted. AWS has once again become a crucial driving force, contributing $42.2 billion in revenue for the quarter and accelerating to a level not seen since the last cloud boom, calming a market anxious about AI costs.

      The specific concern addressed was whether the major cloud providers were investing hundreds of billions in data centers at a faster rate than customers would pay for that capacity. Amazon's response was that demand was exceeding supply. CEO Andy Jassy noted that the demand was so robust that the company’s computing capacity could not fully accommodate customers, even after increasing its expenditures.

      These expenditures are substantial. Amazon raised its planned capital spending by about 10% to around $220 billion, marking one of the largest budget expansions in corporate history, most of which is directed towards AI and cloud initiatives. This spending is manifesting in cash flow, with free cash flow swinging to negative $7.6 billion on a trailing twelve-month basis, down from a positive $18.2 billion a year prior, highlighting the costly nature of the AI race.

      Amazon has been funding this expansion aggressively. The company has taken on billions in new debt to maintain the data center construction, part of a broader borrowing trend among major tech companies.

      The market reacted positively, with at least five brokerages increasing their price targets, concentrating on the AWS reacceleration rather than the cash outflow. Analysts connected the two factors, with JP Morgan expressing optimism about the robust growth in the core AWS segment, which is closely linked to AI revenue, suggesting that the relationship between cloud growth and AI will strengthen.

      This outcome reframes a period of anxiety. Combined capital expenditures among Big Tech have exceeded $600 billion, and each earnings report has become a critical assessment of whether that investment is translating into revenue.

      Amazon’s competitors have encountered similar examinations. Meta recently increased its AI spending guideline despite tightening cash flow, while Microsoft and Alphabet have relied on cloud growth to defend their own expenditures.

      The implications are sector-wide. With Microsoft, Alphabet, and now Amazon all highlighting cloud demand that surpasses their capacity, the discourse has shifted from scrutinizing spending to questioning whether there is enough capacity available.

      Currently, this comparison benefits Amazon. Its shares command a higher earnings multiple than those of Microsoft or Alphabet, indicating that investors are willing to invest more for the growth AWS is demonstrating.

      There is also a hardware narrative at play. Amazon has been developing its own custom AI chips, which Jassy has hinted could evolve into a business worth tens of billions, providing it with a cost advantage over competitors reliant on Nvidia.

      This strategy reflects a focus on vertical integration on a large scale. By developing chips, data centers, and cloud services together, Amazon is wagering it can fulfill AI demand at a lower cost than competitors who purchase their silicon from Nvidia.

      The associated risks have not disappeared, only diminished. If AWS growth falters again while capital expenditures remain around $220 billion, the same cash flow concerns will resurface, and market patience could be limited.

      For the current quarter, however, Jassy achieved the necessary metrics. A reaccelerating cloud business serves as the clearest indication that Amazon's investment in AI is genuinely meeting demand, rather than merely relying on optimism.
