Both trackers report a steep contraction
Global PC shipments fell 20.1% year over year to 62.7 million in Q3 2026, according to IDC’s preliminary figures. That is 15.8 million fewer than the 78.5 million shipped a year earlier. Omdia estimates a 21.2% decline and 58.1 million units. The two trackers agree on a fall of roughly one fifth.
These are separate estimates, not interchangeable totals to average together. Shipments can include deliveries into distribution channels as well as to end users. They do not measure consumer purchases alone or establish a precise decline for the US retail market.
Earlier stockpiling pulled orders forward
IDC attributes part of the decline to vendors and distributors buying ahead of memory-related price increases in the first half of the year. That filled inventories earlier and reduced subsequent orders. Supply constraints and high prices added pressure on demand.
Omdia likewise points to component costs and inventory adjustments. Its desktop shipment estimate fell 23.5%, while notebooks fell 20.6%. Lower shipment volumes do not establish that building a comparable PC has become cheaper.
A holiday discount still needs a comparison
Large inventories can encourage individual promotions. IDC sees scope for short-term offers, while expecting prices to remain above year-ago levels. That complicates the decision to buy now or wait for Black Friday. A sale label alone does not show what changed in value.
Compare the same model’s prior price and full configuration. A cheaper laptop with less memory is not an equivalent discount. For storage changes, our PCIe 4.0 versus PCIe 5.0 SSD comparison explains which differences affect gaming and which specifications may be unnecessary for your use.
