Worldwide PC shipments just fell off a cliff. IDC's preliminary Q3 2026 numbers show 62.7 million units shipped, down 20.1% from a year earlier. Shipments also fell 9.1% from Q2, reversing the usual pattern in which the back-to-school quarter beats the summer one. This is the second consecutive quarterly decline after a 3.8% drop in Q2.

Read the numbers carefully

Nobody escaped. HP took the worst hit, down 30.9%. Dell dropped 25%, while Lenovo fell 22.6% but kept the top spot with 23.8% market share. Apple shipped 5.9 million Macs, down 11.3% from 6.7 million a year ago, yet its share rose from 8.5% to 9.5% because everyone else fell harder.

That is the irony of market-share reporting: a company can claim a bigger slice of a shrinking market. ASUS fell the least among the named vendors, down 8.6%. The unit counts are the fact. The market-share gains are the consolation prize.

The pull-in trick

A big part of this is self-inflicted timing. Vendors and channels loaded up on inventory in the first half of the year, trying to get ahead of memory-driven price hikes. Q1 even nudged up 3% as buyers grabbed the last bargains. Now channels are working through that stockpile instead of ordering new machines.

The pull-in borrowed sales from the second half and left Q3 with little fresh demand. It made the first half look healthier than the underlying market and made the later drop look steeper, but it did not create new buyers.

The AI part

The deeper structural cause is the AI boom eating component supply. AI data-center construction is competing for memory and other parts, driving up prices. Counterpoint reported that NAND memory revenues shot up 3.5 times year over year in Q1 2026 on demand from AI hyperscalers.

IDC had already warned in June that average PC selling prices would rise about 17% in 2026 and that holiday-quarter PC sales would fall around 20%. The uncomfortable part is simple: the infrastructure behind the AI boom is making the computers people use every day more expensive. For someone shopping for a laptop, the industry's enthusiasm for AI does not make the higher price tag easier to swallow.

The practical read

If you need a machine, IDC research director Jitesh Ubrani is unusually blunt. Channels fear carrying too much inventory into a market where high prices are suppressing demand, which could bring promotions and short-term relief. But he does not expect pricing anywhere near a year ago.

Prices will remain elevated, and with macro conditions worsening, the next few quarters could get worse before they get better. Translation: grab a genuine deal if you find one, but do not hold out for a return to old prices. A discount from an inflated sticker price may be the best the market offers for a while.
