The PC market is bleeding — and the AI memory race is killing it

Global personal computer shipments plummeted 20.1% in the third quarter of 2026 compared to the same period a year earlier, according to preliminary data from IDC Research. The decline represents 15.8 million fewer units than in Q3 2025 — the steepest drop since Q1 2023, when the pandemic was still rattling global supply chains.

The numbers get even more alarming when you look at sequential decline: sales fell 9.1% from Q2, completely reversing the seasonal pattern that has always seen Q3 outpace Q2. This was supposed to be the back-to-school quarter, the one driven by students and professionals buying new machines for fall. Instead, it went silent.

What actually happened

The story begins with a phenomenon analysts call the "pull-in" — the act of bringing forward purchases in anticipation of price hikes. In early 2026, PC manufacturers, distributors, and corporate customers rushed to buy before component costs exploded. The result was an artificially inflated first half that left channels overstocked and buyers under-stimulated in Q3.

"What we're seeing is the result of the strong first-half pull-in," Jitesh Ubrani, research director for consumer devices at IDC, told reporters in the company's press release. "Vendors and channels loaded up on inventory early in the year to get ahead of price hikes, and that has thrown off the usual seasonality, where Q3 is typically larger than Q2."

But the pull-in only explains why Q3 was worse than Q2 — not why the entire market is collapsing. The deeper root cause is the global memory and storage shortage, fed by the unprecedented data center buildout for AI.

How AI ate the PCs' memory

Starting in 2024, the explosion of data centers training and running AI models began consuming an ever-larger fraction of global DRAM and NAND capacity. PC manufacturers — who had operated for decades on thin margins and a stable memory market — suddenly found themselves in direct competition with Google, Microsoft, Meta, and Amazon for the exact same chips.

According to Omdia, DRAM and SSD costs now account for nearly 40% of a PC's component cost — up from roughly 15% before. Prices quadrupled since the start of the year. Shortages of processors, graphics cards, and other integrated circuits are compounding the manufacturers' woes.

Apple escaped relatively lightly, with only an 11.3% decline in shipments — enough to increase its market share despite selling fewer machines. Lenovo retained the top spot, but with a 22.6% drop from Q3 2025, sending 14.9 million units. HP fared worse: a 30.9% plunge (10.3 million). Dell lost 25% (7.6 million). ASUS was the only Windows PC maker to grow, up 4%.

What to expect

The outlook is grim. Omdia estimates global PC shipments will fall another 24% year-on-year in Q4 2026 and another 7% across 2027. For context, a 20% single-quarter collapse is an experience the PC market has not endured since the deepest phase of the pandemic.

Micron CEO Sanjay Mehrotra made clear in conversations with analysts that more than 75% of Micron's 2027 output is already committed to AI data center customers. New Micron facilities under construction are not expected to come online until 2028. Experts estimate the situation will not improve until 2029.

For the average consumer, the message is clear: if you were hoping for a good PC to get cheaper, you're probably going to wait another two years. And if you think AI will drive more people to want to buy PCs, think again — the very same AI is making PCs so expensive that many people are simply deferring the purchase.

What happens next is that the AI infrastructure buildout, which promised to accelerate digital adoption, may instead be throttling it — destroying the very consumer hardware market that makes AI accessible in the first place.
