TLDR
- Microsoft and Amazon have invested heavily in AI infrastructure, spending $139 billion combined in 2024 with projections of $185 billion for 2025
- Both stocks have recently stalled after strong performance in the post-2022 market rally
- Concerns are growing about potential AI demand slowdown and excess capacity issues
- Amazon stock dropped slightly (0.3%) amid broader market decline and macroeconomic concerns
- Investors are watching Nvidia’s upcoming Q4 earnings report for signals about the AI market’s health
Microsoft and Amazon are facing increased investor scrutiny as their massive artificial intelligence investments confront a potentially cooling market. The two tech giants, which operate major cloud platforms Azure and Amazon Web Services (AWS), have poured billions into expanding their AI capabilities, but recent market performance suggests growing caution among investors.
In 2024, Microsoft and Amazon spent a combined $139 billion on infrastructure and technology to support their businesses, a dramatic increase from $85 billion in 2023. Industry projections indicate this spending could reach an enormous $185 billion in 2025 as both companies continue building out server capacity to meet client demand for AI computing power.
The artificial intelligence boom began in earnest with ChatGPT’s launch in November 2022, which became the fastest app to reach one million users at that time. This triggered widespread corporate interest in AI technology, with companies across industries rushing to develop their own AI solutions.
Microsoft and Amazon were well-positioned to capitalize on this trend through their cloud computing platforms. As businesses sought the computing power needed for complex AI applications, Azure and AWS became essential partners in the AI revolution. Both companies invested heavily in servers packed with specialized components like Nvidia’s graphics processing units (GPUs).
This strategic positioning initially paid off for investors. Both Microsoft and Amazon performed strongly in the stock market rally that followed the 2022 downturn, with investors rewarding their aggressive AI investments with higher share prices.
However, recent market activity suggests growing concerns about the sustainability of these investments. Both stocks have seen their share prices stall, prompting veteran market analyst Helene Meisler to identify key price thresholds that investors should monitor. Meisler, who has analyzed markets since the 1980s including stints at Goldman Sachs, has established what she calls a “line in the sand” for each company’s stock.
Amazon stock specifically showed weakness on February 25, 2025, slipping 0.3% amid a broader market decline of 0.2% for the S&P 500 and 0.9% for the Nasdaq Composite. Earlier in the trading day, Amazon shares had fallen as much as 4%.
Several factors are contributing to this investor caution. One concern is that AI demand growth might slow from its rapid 2024 pace, potentially leaving Microsoft and Amazon with excess capacity. There are also worries about new, cheaper AI alternatives entering the market, like DeepSeek’s chatbot that reportedly cost much less to develop than ChatGPT.
Macroeconomic factors are adding to the uncertainty. Last year’s stock rally was partly fueled by expectations of Federal Reserve interest rate cuts, which would have made corporate debt cheaper and improved returns on new investments. However, those expectations have largely disappeared as inflation has begun to increase again.
Trump policies creating market anxiety
The incoming Trump administration’s policies are creating additional market anxiety. Plans for new tariffs on China and Mexico could drive up inflation, while proposed restrictions on semiconductor exports to China might impact the tech sector broadly.
Investors are now looking to Nvidia’s upcoming quarterly earnings report for clues about the AI market’s health. As a leading provider of the specialized chips powering AI systems, Nvidia’s results and guidance could significantly impact valuations for companies heavily invested in AI infrastructure, including Amazon and Microsoft.
The AI boom has spread far beyond tech companies. Financial institutions like JP Morgan are using AI to manage risk, healthcare companies are applying it to drug development, and retailers are implementing AI solutions for supply chain management and loss prevention. Even the U.S. military is exploring AI applications in partnership with data analytics companies like Palantir.
While artificial intelligence isn’t new – with roots tracing back to Alan Turing’s work in the 1950s and Rand Corporation’s first AI program in 1956 – its recent mainstream adoption has transformed it from science fiction concept to business reality. The question now facing investors is whether Microsoft and Amazon’s massive AI investments will deliver the expected returns in a potentially changing market landscape.
Amazon’s stock closed at $212.80 on February 25, with the company maintaining a market capitalization of approximately $2.3 trillion despite the day’s slight decline.
