PC Market Plummets in Q3: Sales Drop by Over 20%

The weakness is felt across the entire traditional PC landscape. According to Omdia, notebook shipments, including mobile workstations, fell by 20.6% to 46.4 million units. Desktop PCs saw an even steeper decline of 23.5%, dropping to 11.7 million units. This downturn is particularly notable given the timing; the third quarter typically serves as a preparation phase for the holiday season, yet the expected seasonal surge failed to materialize in 2026.

Analysts attribute part of this slump to a "pull-forward effect." During the first half of the year, OEMs and retailers aggressively stockpiled components to hedge against anticipated price hikes and supply chain disruptions. This resulted in high inventory levels across the supply chain. Coupled with rising end-user prices, this has created a difficult environment where manufacturers face excess stock while consumers remain hesitant to purchase.

Perhaps the most significant shift, however, is in the cost structure of hardware. Historically, DRAM and SSDs accounted for approximately 15% of a typical PC's component cost. Today, Omdia reports that this share has surged to nearly 40%, driven by a more than fourfold increase in component prices. This fundamentally alters the economics of PC manufacturing. For low-margin devices like budget notebooks or office PCs, manufacturers are left with few options: raise retail prices, reduce RAM and SSD capacities, switch to lower-quality components, or accept thinner margins.

The memory market is simultaneously under immense pressure from the data center sector. AI accelerators require massive amounts of HBM, server platforms demand high-capacity DDR5, and AI storage consumes vast quantities of NAND. Consequently, consumer products are indirectly competing with much higher-margin data center products for wafers, manufacturing capacity, and capital investment. While a single NVIDIA GPU might not directly dictate the price of a RAM stick, the industry's shift toward high-margin AI infrastructure is fundamentally reshaping the economic priorities of semiconductor manufacturers.

Despite the market contraction, the hierarchy of major manufacturers remains largely intact. Lenovo maintains its top position with 14.9 million units and a 26% market share. Other major players include Dell (7.6 million), Apple (6.8 million), and ASUS (5.4 million). Notably, Apple managed to increase its market share despite an 11% decline in shipments. This is attributed to its premium positioning; buyers of high-end systems appear less sensitive to rising component costs than those in the budget segment.

Optimism for a quick recovery is scarce. Omdia forecasts a further 24% decline for the fourth quarter of 2026 and predicts a 7% decrease for the full year 2027. This suggests that the third quarter may not be the bottom, but rather the beginning of a prolonged downward trend driven by the structural shift in the semiconductor industry's focus.
