Early stockpiling drove much of the 20% third-quarter fall in PC shipments, IDC says

Part of the 20.1% comes from timing. Many manufacturers stocked up in the second quarter to get ahead of expected price rises, Tom's Hardware reported, and those units were missing from the third-quarter count ^[8]. "What we're seeing is the result of the strong first half pull-in. 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," said Jitesh Ubrani, IDC's research director for consumer devices ^[9].

Working back from IDC's percentages, the third quarter of 2025 shipped about 78.6 million units and this one about 62.8 million ^[14][15]. That puts the second quarter of 2026 at roughly 69.1 million ^[16].

So the 20.1% does not measure a fifth of PC memory supply disappearing in three months. The data-center effect shows up in price. Memory makers have moved production toward the HBM that AI GPUs need, leaving less capacity for consumer memory, according to Tom's Hardware ^[5]. Its readers say they will not upgrade their systems in the next two years ^[21].

The stock now sitting in the channel matters most in the near term. "Channels are now worried about carrying too much inventory into a market where high prices are suppressing demand. That could translate into promotions and some short-term relief for consumers, but we don't expect pricing anywhere near what it was a year ago. Prices will remain elevated," Ubrani said ^[10]. "With macro conditions worsening, the risk is that the outlook for the next few quarters gets worse before it gets better," he said ^[11].

The sources split on how long prices stay high. Micron says the situation will not improve for the next few years, and Tom's Hardware cites estimates that it will not improve until 2029 ^[18][17]. Acer CEO Jason Chen called those fears hype meant to protect the margins of memory chip makers ^[19]. Micron is one of the memory makers in question ^[5][6]. Chen expects PC prices to decline by the second half of 2027 as Chinese memory chip capacity comes online ^[19].

On this record, elevated prices through most of 2027 are common ground. IDC's analyst expects prices to stay high, and Chen's optimistic case has them falling only in the second half of that year ^[10][19]. The case for several more years depends on Micron's outlook holding, and it fails if Chinese capacity arrives on Chen's schedule ^[18][19].
