IBM Falls 2.7% in 15 Minutes After Cutting 2026 Revenue Growth Outlook

At 5:17:09 p.m. ET on July 22, 2026, IBM projected constant-currency revenue growth of 4%-5% for 2026. IBM shares initially rose from $208.28 to $209.00, then reversed to $204.60 at 10 minutes, down 1.767%, and $202.67 at 15 minutes, down 2.693%. The first-minute uptick did not hold; the decline developed afterward and was still deepening at the final available checkpoint.

The new range lowered IBM's growth outlook

IBM's July 22, 2026 earnings materials confirmed the full-year constant-currency revenue-growth range. Reuters reported on July 22, 2026 that the 4%-5% projection was a reduction from IBM's previous outlook and followed weaker-than-expected second-quarter results.

The revised guidance did not introduce the underlying concern for the first time. A July 14, 2026 Reuters report said IBM had warned that customers were redirecting spending toward supply-constrained servers, storage and memory, leaving less budget for other technology purchases. IBM also said several large transactions had not closed when expected.

The stock rose first, then broke lower

IBM was $208.28 when the guidance headline crossed and reached $209.00 after one minute, a gain of 0.346%. The direction then reversed. At 10 minutes, the stock was $204.60, representing a 1.767% decline from the headline-time price.

The selloff extended over the next five minutes rather than stabilizing. IBM traded at $202.67 at 15 minutes, widening the measured decline to 2.693%. The move from $204.60 to $202.67 shows that the negative reaction remained active after the first 10-minute reading.

The guidance formalized an existing spending concern

The market narrative was broader than a single percentage range. IBM had already described customers prioritizing AI-related infrastructure purchases and delaying other large technology transactions. The new annual forecast converted that operating pressure into a lower company-wide growth expectation.

The observed sequence supports describing a negative reaction following the revised outlook: a small first-minute rise, a reversal by 10 minutes and a deeper loss by 15 minutes. It would overstate the record to say the 4%-5% range alone caused the entire decline. The update arrived alongside IBM's quarterly results and management commentary about software demand, mainframe activity and delayed customer spending.
