A sharp reversal in technology stocks sent shockwaves through global markets Tuesday, as investors abruptly shifted focus from geopolitical concerns to mounting doubts about the valuations and spending patterns of artificial intelligence companies that have powered year-long rallies.
The Nasdaq, heavily weighted toward tech, closed down 2.2%. The S&P 500 fell 1.43% by afternoon trading. The Dow held relatively steady. The slide erased some of the gains that have defined 2024, with the Nasdaq up 10% for the year, the S&P 500 ahead 7.3%, and the Dow having climbed 6% to cross 51,000 points.
The catalyst arrived Monday when Alphabet, Google's parent company, delivered its worst trading day in over a year. The stock dropped 5% after news that two prominent AI researchers had departed, signaling potential talent drain at a moment when the company's strategic direction is under investor scrutiny. The broader market took note.
SpaceX, the rocket company that went public June 12 with considerable fanfare, cratered 16% on the same day. Management announced plans to raise $20 billion through bond sales despite pulling in over $85 billion from its initial public offering, a move that raised eyebrows about the capital intensity of its projects and whether debt financing of infrastructure spending is spiraling.
The weakness crossed borders overnight. South Korea's benchmark index fell 10% on Tuesday as the country's leading chipmakers, SK Hynix and Samsung Electronics, both shed over 12%. Japan's Nikkei 225 dropped 3.5% at the closing bell. London's FTSE 100 managed to hold steady, offering a rare pocket of stability.
What spooked traders is a concern that has been building for months: whether the concentration of market gains in a handful of mega-cap tech firms represents unsustainable excess. Seven companies now represent 30% of the S&P 500's total value. Compare that to the dot-com era, when similar concentration preceded a brutal collapse.
Analysts point to Morgan Stanley estimates projecting AI-related debt issuance will exceed $500 billion this year as evidence that the spending spree may be financing itself increasingly through borrowed money. With the Federal Reserve signaling last week that rate hikes may return as a tool against inflation, the cost of that borrowing would rise sharply, pressuring the business models that depend on cheap capital.
Ipek Ozkardeskaya, a senior analyst at Swissquote, noted that SpaceX's bond sale announcement, coming so soon after its IPO windfall, suggests Big Tech may be locked in an unsustainable infrastructure arms race. The bond markets, historically a canary in the coal mine for investor confidence, are beginning to flash warning signs.
The sell-off carried an unmistakable message: the long party fueled by AI enthusiasm and seemingly endless capital availability may be approaching a reckoning.
Author James Rodriguez: "When a $85 billion IPO needs another $20 billion in borrowing weeks later, something is broken in how we're financing this boom."
