Global PC shipments collapsed in the third quarter of 2026, dropping 20.1 percent year-over-year to 62.7 million units, according to IDC—the steepest third-quarter decline on record.
Omdia reported an even steeper 21.2 percent fall to 58.1 million units. Desktop shipments (including workstations) fell 23.5 percent to 11.7 million units; laptops dropped 20.6 percent to 46.4 million units.
The decline marks a sharp reversal from Q2 2026, when 68.2 million units shipped—an unusual quarterly dip, since Q3 typically outpaces Q2.
The root cause: AI demand has strangled memory supply. Since 2025, ravenous appetite for high-bandwidth memory and server DRAM for AI workloads has starved the consumer DRAM pool. Memory and storage components now consume nearly 40 percent of PC bill-of-materials costs, compared with a historical 15 percent baseline. PC prices have quadrupled.
Channels amplified the damage. Vendors and sales partners frontloaded inventory earlier in 2026 to lock in lower memory prices ahead of anticipated spikes. As those price increases hit in Q3, demand evaporated—customers balked at the premiums—leaving channels bloated with stock.
"Channels are now concerned about holding inventory in a market where high prices suppress demand," said Jitesh Ubrani, research director for consumer devices at IDC. "This could lead to near-term promotions, but elevated prices will persist."
Vendors and ODM partners responded by throttling production in Q3, compounding the mismatch.
Ishan Dutt, research director at Omdia, attributed the decline directly to component cost increases that fully rippled through end-market pricing. "Consumers and IT decision-makers scaled back purchases," Dutt said.
IDC projects only modest and brief price relief ahead. The structural constraint—AI data centers consuming the lion's share of premium memory output—shows no sign of abating.
