For an extended period, major U.S. tech firms enjoyed an unspoken arrangement with their investors: they could indulge in extravagant spending on artificial intelligence initiatives, and as long as revenues continued to rise, the stock market would respond favorably. However, that understanding appears to be unraveling.
On Thursday, Alphabet Inc.’s stock experienced a significant decline of over 7%, marking its steepest drop in more than a year. This downturn coincided with the company's announcement of projected capital expenditures soaring to $205 billion by 2026, while also revealing that its free cash flow turned negative in Q2—something that hadn't happened since its IPO in 2004.
Despite Alphabet reporting an impressive 82% year-on-year increase in cloud-computing revenue, significantly exceeding market expectations, investor sentiment soured due to escalating expenses. “Investors are currently fixated on capital expenditures,” noted Jason Lemire, chief investment officer at Bold Wealth Partners. “In previous times, higher expenditures were viewed positively; now, the trend favors lower spending.”
This market reaction illustrates a remarkable shift in investor sentiment surrounding AI and the major tech contenders, often dubbed the "Magnificent Seven." The increase in capital expenditures has made it challenging to satisfy investor expectations, especially considering that Alphabet has been regarded as a frontrunner in AI, largely due to its successful Gemini AI services and flourishing cloud-computing unit.
This evolving landscape is particularly foreboding as the upcoming earnings reports from industry heavyweights like Microsoft and Meta Platforms are set to be released next week, followed by Apple and Amazon.
The index that tracks the Magnificent Seven, which includes companies like Nvidia Corporation and Tesla Inc., fell by 4.8% on Thursday, marking its worst day since the announcement of Trump’s tariff measures in April 2025. So far in 2026, the index has declined by 3.7%, a stark contrast to its previous three years of robust growth. Consequently, the corporations that have dominated the S&P 500 Index post-AI boom are increasingly losing ground to chip manufacturers receiving a portion of the capital investments, such as Micron Technology Inc. and Advanced Micro Devices Inc.
Microsoft, initially seen as a leader in the AI arena due to its investment in ChatGPT developer OpenAI, is currently the second-weakest stock among the Magnificent Seven, plummeting by 21% this year amid fears of lagging behind its competitors despite planning over $190 billion in capital expenditures for the year. Meta’s shares have fallen 9.8%, as investors express skepticism about its AI strategies, while Amazon’s stock remains largely unchanged for 2026.
Together, Alphabet, Microsoft, Amazon, and Meta are anticipated to invest around $724 billion in capital spending this year and nearly $950 billion in 2027, per analyst estimates compiled by Bloomberg.
“We find ourselves in an environment where there is a trend towards sell-offs related to capital expenditures," said Willy Lee, principal at Neostellar Capital. "With these companies going hand-in-hand with Alphabet in spending, deeper scrutiny across all areas of their operations is imminent.”
The investor backlash is also sharpening focus on firms that benefit from these expenditures, particularly chipmakers. The Philadelphia Stock Exchange Semiconductor Index, having surged 101% in the first half of the year, dropped 17% in July and is headed for its worst monthly performance since June 2022, which was during a broader stock market slump associated with inflation.
The uncertainty is evident in the extreme volatility of the 30-member chip index, which has recorded its highest fluctuations since 2020. This year alone, the index has experienced 17 swings of 5% or more, matching the most it’s seen since 2008, according to Bloomberg data. In contrast, neither the S&P 500 nor the tech-heavy Nasdaq 100 Index has encountered similar turbulence.
“There will inevitably be a downturn in AI,” stated Lemire from Bold Wealth. “When you examine the remarkable profit margins—especially in memory—it's unsustainable over time. At some point, we will witness margin and valuation compression, which will significantly impact the market.”
Conversely, Apple has strategically sidestepped exorbitant AI investments, choosing instead to collaborate with model developers to enhance its services. This prudent approach has been rewarded by investors, with Apple shares rising 15% in July, positioning the company for its best month in three years, and contributing 23% to the S&P 500’s 8.3% increase this year.
However, Apple is not immune to challenges. The surge in demand for memory chips tied to AI has forced Apple to adjust prices for products like MacBooks and iPads. The implications for its customer base and overall profit margins remain uncertain.
Despite the recent downturn among the Magnificent Seven, some stocks have become more attractively priced. For instance, Microsoft is now valued at 19 times projected profits, a significant reduction from its average of 27 over the last decade. Similarly, Meta trades at approximately 14 times, compared to its 10-year average of 20.
The rush for investment in AI capacity is reshaping business models and introducing new risks. Alphabet's negative cash flow in Q2 has raised eyebrows among investors who are acutely aware of its diverse revenue sources.
All of these dynamics have rendered historical valuation metrics less relevant, as emphasized by Brad Warden, a senior portfolio manager at Nomura Asset Management, whose fund includes investments in Nvidia, Alphabet, Microsoft, and Amazon.
“Current prices may seem attractive, but in light of potential disruptions, they face the presumption of guilt until proven innocent. Is the business model viable in the long term? Will conditions deteriorate?” Warden remarked, expressing a belief that the AI investments will eventually bear fruit. “The crux of the matter lies in the pain threshold investors are willing to accept and their conviction that they will reap rewards from the investment cycle in the end.”
