IBM Plummets 26% on Weak Guidance as Big Banks Report Blockbuster Earnings

IBM's stock plummeted 26% on July 24, 2026—the worst single day in the company's history, surpassing even the crash of Black Monday in 1987—after the technology giant issued preliminary earnings that fell short of Wall Street expectations. The miss itself was modest in absolute terms: revenue would come in at $17.2 billion instead of the anticipated $17.9 billion, a gap of roughly $700 million. But the reason behind that shortfall sent shockwaves through the market. CEO Arvind Krishna explained that in the final weeks of June, IBM's enterprise clients had abruptly redirected their capital spending away from Big Blue's software and services toward hardware—servers, memory, and storage. The shift suggested something deeper than a simple quarterly hiccup.

On the surface, a $700 million revenue miss on a $17 billion base should not trigger a 26% collapse. Earnings per share came in at 293 cents versus expectations of 302 cents, also a modest miss. Yet institutional investors and traders seemed to be pricing in a larger story. The preliminary nature of the warning itself was the real red flag. Companies rarely pre-announce earnings unless the news is especially grim. What spooked the market was the underlying question: Was this a temporary reaction by customers trying to lock in hardware supplies before anticipated price increases, or had the nature of enterprise spending fundamentally shifted, revealing that IBM's services were discretionary rather than essential infrastructure?

The timing added to the uncertainty. Memory prices had spiked recently—Apple had raised its own prices partly because of memory costs—and Micron had signaled that supply would remain tight well into 2027. That suggested clients might indeed be front-loading hardware purchases to hedge against future price hikes. But the shift also raised a darker possibility: that as companies invested heavily in artificial intelligence infrastructure, they were prioritizing the raw computing power and storage they could buy from hardware makers over the consulting and software services IBM provided. If that trend was structural rather than cyclical, IBM faced a more serious problem.

The contrast with the banking sector could not have been starker. On the same day IBM crashed, JPMorgan Chase, Bank of America, Wells Fargo, Goldman Sachs, and Citigroup all reported blockbuster earnings that exceeded expectations by wide margins. JPMorgan reported earnings per share of $7.70, nearly $2 above consensus, and beat revenue expectations by about $7 billion. The gains were not driven by a single factor. Equity trading revenue surged—Goldman Sachs alone brought in $7.5 billion from equities trading in the quarter—but that was only part of the story. Mergers and acquisitions activity had reached $3 trillion globally in the first half of 2026, the highest level since 2021. Wealth management inflows surged as investors pulled money off the sidelines. JPMorgan reported 44,000 first-time investors opening accounts. Goldman's assets under management grew 20% year over year, outpacing the market itself.

Beyond the headline trading and investment banking gains, the banks benefited from less-discussed but equally important trends. Net interest income—the spread between what banks pay depositors and what they earn on loans—remained robust even with the Federal Reserve on hold. JPMorgan raised its full-year net interest income guidance by $2.5 billion from April's forecast. Loan growth remained strong, and the internal rate dynamics, the gap between deposit costs and lending rates, proved better than expected. Credit quality held up remarkably well. The big banks reported lower-than-expected charge-offs across the board, suggesting that despite economic headwinds—inflation, geopolitical tensions—consumers and businesses remained financially healthy.

Citigroup, long the punchline of banking sector discussions, emerged as an unexpected bright spot. CEO Jane Fraser's restructuring program appeared to be working ahead of schedule. The bank raised its dividend by 12% and announced a $30 billion share buyback program, signaling management confidence that the stock was undervalued. For investors, the message from the banking sector was clear: the financial system was not just surviving but thriving. The stress tests that banks had passed weeks earlier, which some feared might constrain capital deployment, seemed to have had little dampening effect on the actual results or the enthusiasm surrounding them.

The contrast between IBM and the banks illustrated a fundamental shift in how capital was flowing through the economy. Enterprise spending was not weak—it was simply being redirected. Companies had money to invest, and they were choosing to spend it on the infrastructure that would power artificial intelligence and digital transformation: hardware, memory, and the services of investment banks facilitating deals. IBM's problem was not that its customers lacked capital but that those customers had decided that IBM's particular offerings were less urgent than the raw computing power and deal-making expertise available elsewhere. Whether that preference would prove temporary or permanent remained the central question for IBM investors watching the stock trade back to levels not seen since May.
