Why Is IBM CORP (IBM) Stock Moving Today?

IBM stock is moving sharply lower today, down 24.2 percent in a single session to $219.42 as of the close. The decline follows preliminary earnings guidance that signaled a significant shortfall in second-quarter revenue and earnings per share. The company attributed the miss to a shift in customer spending toward AI hardware, which has caused a corresponding reduction in software and services demand.

What Happened

IBM issued a profit warning that rattled the software sector, triggering a 24 percent plunge in its shares, the largest one-day drop since 1968. The company reported that customers are reallocating budgets away from software and toward AI hardware, which has disrupted its expected revenue streams. This shift has raised concerns about the broader software industry's resilience in the face of rapid AI adoption. Analysts and market participants are interpreting the move as a sign that AI spending is accelerating in ways that IBM is not fully positioned to capitalize on, at least in the near term. The stock has lost nearly a third of its value over the past week, erasing $70 billion in market capitalization.

What The Data Shows

IBM's stock has printed 24 fresh 52-week lows on July 16, 2026, reflecting the severity of the sell-off. Over the last eight trading sessions, the stock has fallen from $289.32 to $219.42, a drop of 24.2 percent. The unusual options activity in the past 36 hours shows a total call premium of $19.1 million and put premium of $20.6 million, with the largest single print reaching $11.3 million. Retail traders on r/wallstreetbets have speculated that the move is an overreaction, with some calling it an opportunity to buy. Congressional transactions in the last 90 days include 21 buys and 17 sells, with the most recent filing on July 6, 2026.

What To Watch

The company has not scheduled an earnings date at this time. Investors should monitor the breadth of coverage and sentiment shifts in the coming days, particularly as more analysts weigh in on the implications of IBM's earnings warning for the AI and software sectors.
