The artificial intelligence arms race among major technology companies is now facing a critical test of investor patience. As Microsoft, Meta Platforms, Inc., and Amazon.com prepare to release their quarterly financial reports this week, the market's primary focus has shifted from revenue growth to a more fundamental question: when will the continuously expanding capital expenditures finally yield returns?
This backdrop of intense scrutiny has been set by Alphabet's recent performance. The company reported its highest-ever quarterly profit of $112.1 billion, yet its stock price fell over 7% immediately after. The trigger was investor concern over the company raising its 2026 capital expenditure forecast by $15 billion.
Collectively, Alphabet, Microsoft, Meta Platforms, Inc., and Amazon.com are expected to invest a combined $700 billion in capital expenditures this year. Wall Street projections suggest this figure could surpass $1 trillion by 2027.
The fragile market sentiment creates a tense environment for the upcoming earnings calls from these three companies. According to UBS Global Wealth Management, "Limited visibility into capital expenditures after 2027, combined with investors' increased demands for spending discipline, will likely continue to suppress risk appetite." Meanwhile, Moody's, a Fitch Ratings affiliate, recently warned that sustained capital expenditure plans could "threaten credit quality," noting that six major tech companies collectively hold approximately $460 billion in direct debt.
Microsoft: Azure Momentum is Strong, Copilot Monetization Enters a New Phase
Among the three companies, Microsoft faces the most clearly defined performance expectations. Analysts forecast that Microsoft's capital expenditures for the current quarter will surge 74% year-over-year. Simultaneously, the market holds high expectations for the growth of its Azure cloud service.
A research report from Morgan Stanley indicates that its analysts are confident in Microsoft achieving approximately 41% constant-currency growth for Azure in the fourth fiscal quarter. This would be about one percentage point higher than the upper end of management's guidance of 39% to 40%. Morgan Stanley's confidence stems from positive feedback from channel partners, improving GPU supply capabilities, and its own survey of Chief Information Officers (CIOs). In cloud migration scenarios, 72% of CIOs expect to increase their investment in Microsoft solutions over the next year, positioning Microsoft as the leading vendor in capturing incremental IT budgets.
The commercial progress of Copilot is also a major focus. In the third fiscal quarter, paid seats for Microsoft M365 Copilot grew from 1.5 million to 2.0 million, with management guiding that net additions of paid seats will continue to increase quarter-over-quarter. Morgan Stanley notes that the monetization path for Copilot is evolving into three parallel growth drivers: direct seat sales, customers migrating to the higher-value E7 subscription plans, and consumption-based AI service pricing. Notably, the price increase for Microsoft's commercial M365 took effect on July 1, 2026, for new customers. Morgan Stanley estimates this pricing adjustment will contribute incremental revenues of approximately $2 billion, $4 billion, and $6 billion in fiscal years 2027, 2028, and 2029, respectively.
Regarding capital expenditure, Morgan Stanley believes street estimates remain conservative and have room for upward revision. Management previously disclosed that capital expenditure for the 2026 calendar year is expected to be around $190 billion, with approximately $25 billion attributed to component price increases. The firm maintains an "Overweight" rating on Microsoft with a price target of $600, arguing that the current forward price-to-earnings ratio of about 16 times for fiscal 2028 is "too cheap" and fails to fully reflect the company's sustained high-growth potential.
Meta Platforms, Inc.: User Growth Peaks, Capital Expenditure Guidance May Be Significantly Raised
The situation for Meta Platforms, Inc. is more complex. According to Bloomberg Intelligence (BI) analysis cited by Bloomberg, Meta Platforms, Inc. may "significantly" raise its capital expenditure guidance to cope with rising component costs, which was precisely the core catalyst that triggered the stock price decline for Alphabet last week.
At the same time, user growth is facing new pressure from the regulatory front. As regulators in various regions advance legislation to restrict teenagers' use of social media, the user growth prospects for Meta Platforms, Inc. will face greater headwinds. The "Family Daily Active People" metric, which measures daily active users across its four core applications, is expected to record its weakest growth rate since 2021.
Amazon.com: AWS Growth Could Hit a New High Since 2022
Compared to Microsoft and Meta Platforms, Inc., market expectations for Amazon.com's upcoming earnings report appear more optimistic. According to Truist analysis cited by Bloomberg, Amazon.com's overall revenue growth could reach 17%, the highest in nearly five years. Amazon Web Services (AWS) growth is expected to exceed 30%, marking a new high since 2022. Strong demand for AI-related services is seen as the core driver of AWS's growth.
However, Amazon.com also faces questions regarding its capital expenditure plans. Following the stock price decline of Alphabet after it raised its spending forecast, investors remain highly alert to whether these three companies will further increase their capital expenditure outlook for 2027 and beyond.
Moody's Warns: Balance Sheets Under Pressure, Credit Risks Emerge
A research report from Moody's last week set a serious tone for the upcoming earnings season. The agency pointed out that Alphabet, Microsoft, Amazon.com, Meta Platforms, Inc., Oracle, and CoreWeave are transitioning from an asset-light software, intellectual property, and cloud services model to an asset-heavy model requiring an "unprecedented scale of investment." This trend could strain the credit metrics of these companies.
Kevin McNeil, a Vice President at Moody's, stated on the agency's podcast, "These are large, well-established companies with balance sheets that are, in many cases, pristine. But they are undertaking capital commitments that are approaching historic levels. The increased capital intensity could lead to negative free cash flow or at least a significant contraction for some of these companies." He further noted that debt financing "could increase leverage and introduce additional risk to the balance sheet."
Among the six companies under scrutiny, Oracle is in the most precarious position. Moody's has revised its credit rating outlook for Oracle to negative, with its Baa2 rating just two notches above junk status. Just last month, another rating agency, S&P Global, downgraded Oracle to just one notch above investment grade. In contrast, Alphabet, Amazon.com, Meta Platforms, Inc., and Microsoft currently maintain robust balance sheets and investment-grade ratings that are not in immediate danger.
The Bull vs. Bear Debate: Will AI Investments Pay Off or Overextend the Future?
The market is clearly divided on the issue of continually expanding capital expenditures. The core logic of the bulls is that demand is real, and the constraint on growth is supply, not demand. For example, regarding Microsoft's Azure, Morgan Stanley points out that CFO Amy Hood explicitly stated in the last quarter's earnings call that Azure's guidance is essentially "allocated capacity guidance." The growth constraint comes from the pace of data center construction and GPU deployment, not customer demand. As Microsoft plans to double its total data center capacity over the next two years, this constraint is expected to ease gradually.
Bears, however, focus on the lack of visibility into returns. UBS Global Wealth Management points out that "limited visibility into capital expenditures after 2027" is a key factor suppressing investor risk appetite. Moody's warning is more direct: the shift from an asset-light to an asset-heavy model is eroding the high free cash flow advantages that these companies have historically prided themselves on.
For long-term investors, UBS still recommends holding their positions. "For long-term investors with diversified portfolios, maintaining investment is the most effective strategy to navigate current uncertainty. Given strong earnings growth and a improving cyclical backdrop, attractive stock opportunities exist across sectors and regions." However, with Alphabet's recent experience as a cautionary tale, the market's verdict is clear: good performance is not enough; companies must also manage their spending carefully.
