Global personal computer shipments fell 20.1 percent year over year in the third quarter of 2026, marking the steepest decline for a third quarter ever recorded. The industry shipped 62.7 million units, down from 78.5 million units in Q3 2025, according to IDC. Omdia's data painted a similar picture: global shipments of laptops, desktops and workstations declined 21.2 percent year over year to 58.1 million devices—the industry's sharpest overall decline since Q1 2023.

Desktop PC shipments fell 23.5 percent to 11.7 million units. Laptop shipments declined 20.6 percent to 46.4 million units. The sequential drop from Q2 to Q3—down 9.1 percent from 68.2 million units—signals structural demand weakness, not seasonal softness; Q3 shipments typically exceed Q2 figures.

The economics are unforgiving. Memory and storage now account for nearly 40 percent of the bill of materials for PC manufacturing, up from a typical 15 percent, according to Ben Yeh, principal analyst at Omdia. PC prices have climbed more than fourfold during this period.

The root cause sits upstream: since 2025, surging demand for high-bandwidth memory and server DRAM for artificial intelligence workloads has starved consumer PC, smartphone and gaming console production of manufacturing capacity. PC vendors and sales channels anticipated this squeeze and stocked inventory earlier in the year. The strategy backfired. Demand cratered as consumers and IT decision-makers balked at elevated prices, leaving channels holding excess stock.

Jitesh Ubrani, research director for consumer devices at IDC, said sales channels are now concerned about carrying that bloated inventory into a market where high prices suppress demand. Price relief may come through short-term promotions, but Ubrani warned that prices will remain elevated overall. IDC expects only modest, brief relief.

Ishan Dutt, Omdia research director, said the Q3 drop was expected. Component cost increases have fully hit end-market pricing, triggering a demand pullback from both consumers and IT decision-makers. On the supply side, vendors and their ODM partners scaled back production in Q3 to match the weaker demand, while channel partners continued managing their swollen inventory.

Ubrani flagged downside risk: worsening macroeconomic conditions could force the outlook to deteriorate over the next few quarters before any recovery materializes.
