Global PC shipments plunged about 20% year-over-year in Q3 2026, a decline equivalent to roughly 15.8 million fewer units, according to IDC; Omdia reports a similar 21% fall and IDC also records a 9% quarter-on-quarter drop. The slump is concentrated in consumer and enterprise buying as higher component costs have translated into sharply higher retail PC prices, suppressing demand. Industry analysts explicitly link the downturn to memory and storage inflation rather than weaker product cycles, with dramatic declines seen across desktops and laptops as buyers delay purchases or hunt for deals.
The driver is the AI-led surge in demand for DRAM and SSDs, which has pushed those components from about 15% of a PC’s bill to around 40%, and sent global DRAM revenue projections from $151 billion last year toward roughly $372 billion this year. OEMs and channels, having stockpiled inventory to buffer cost spikes, now face excess supply and low demand, making short-term promotions likely even though average prices remain elevated. Analysts warn macroeconomic headwinds may deepen the decline in the coming quarters, so any near-term discounts could be temporary before prices rise again.
