Published Tuesday, November 3, 2026, the morning of the midterm elections, as the week’s earnings reports roll in.
Our thesis: the AI build-out has a cost that does not show up in any cloud company’s spending plan: it is paid by everyone else who needs memory chips. Apple’s report on Monday is the clearest example so far. We think the market is about to sort tech into companies that sell scarce parts to the AI build-out and companies that have to buy those parts, and that, as in every earlier memory boom, the shortage is a cycle that will eventually turn.
What Apple just told us
Apple reported a record September-quarter revenue of $114.5 billion, up 12% from a year earlier, and earnings of $2.10 per share, ahead of the $1.99 analysts expected (Apple; estimates from LSEG via CNBC). The stock still slid roughly 2% to 3% in extended trading, because of what came next. Apple guided its December-quarter gross margin to 45% to 46%, below the 47.9% it just reported and below the 46.3% analysts had expected. Management said most of that drop comes from higher memory costs.
The wording was strong. CEO John Ternus called current memory pricing “unprecedented,” and the company said it expects memory purchase prices to keep rising beyond December (earnings call transcript via Investing.com). Apple has already raised iPhone prices by $100 and lifted some Mac prices, and its purchase commitments rose by $33 billion during the quarter as it worked to lock in supply (Reuters via StreetInsider). One detail matters for the rest of this piece: the 47.9% margin included about one point from tariff refunds, so the underlying squeeze is already visible.
Why memory is the pressure point
TrendForce, a research firm that tracks memory prices, expects conventional DRAM contract prices to rise 10% to 15% in the fourth quarter from the third, and flash storage prices 15% to 20% (TrendForce). The reason is a choice by the three big suppliers. Server memory and the high-bandwidth memory used with AI chips earn more, so they are steering their best factory capacity there, and what is left over for phones and laptops costs more. TrendForce describes the overall market as undersupplied.
The squeeze shows up in sales. IDC, quoted by CNBC, expects smartphone shipments to fall nearly 17% this year and PC shipments about 11%, and notes that consumers are holding on to old computers longer. On Friday, Intel lost 29% in a day, its worst since the 1970s, after citing PC softness in its forecast (CNBC). Intel’s trouble has its own causes, but it fits the same picture: when parts cost more, buyers wait.
Illustrative example, not real data.
Picture a town with three cheese makers and thousands of pizza shops. A new chain of restaurants starts buying cheese in huge amounts and pays well, so the cheese makers send most of their output to the chain. The small pizza shops now pay more for what is left, raise their prices, and sell fewer pizzas. Everyone agrees the chain is growing fast; the shops are simply the ones paying for it. The numbers here are made up to show the idea.
History: memory shortages end, and not gently
Memory has always been a boom-and-bust business, because high prices make suppliers build more capacity and customers buy extra stock, and then both turn around at once. Micron’s own annual report shows how violent the swings are: average DRAM selling prices rose 19% in 2017 and 37% in 2018, then fell 30% in 2019 (Micron annual report).
2018. That boom was also driven by cloud computing and smartphones, and many argued that three big suppliers would stay disciplined. TrendForce reported that contract prices started sliding in October 2018, ending an upswing that had lasted more than two years, as the market moved into oversupply with high inventories at suppliers and buyers alike (TrendForce). Micron’s management said customers who had stockpiled during the long rise were now working down their inventories (Motley Fool).
2021 to 2023. The pandemic version repeated it. Asset manager Baillie Gifford notes that by 2023 Micron’s DRAM prices had fallen almost 50% and its NAND prices by more than 50%, with negative gross margins and large inventory write-downs (Baillie Gifford). The lesson in that piece is one we share: demand, industry consolidation and discipline can all be real, and prices can still collapse once supply catches up.
What is different this time
The buyer is new. Earlier booms were led by phones and PCs, which are many small customers who can walk away. This one is led by a handful of cloud companies that sign long-term deals, and TrendForce notes those contracts are one reason some price increases are lagging the market. That may make the demand stickier than in 2018. It also means the cycle depends heavily on whether those few buyers keep spending. Last week’s market was nervous about exactly that: the Philadelphia semiconductor index fell 15% in October (Charles Schwab). Schwab’s own read is more measured, pointing out that Alphabet confirmed higher capital spending next year and Amazon’s plans looked firm.
Apple is also not a typical buyer. It spent only $2.24 billion on capital projects last quarter, far less than the cloud giants, and Barclays wrote before the report that the pricing benefits Apple had enjoyed from its scale and preferred terms were fading (CNBC). If a company with that much leverage is warning about margins, smaller device makers have less room to absorb the same costs.
What we watch this week
- AMD, today after the close. Its commentary on AI chip demand and on the supply of memory it needs. AMD is among the names that fell in last Friday’s semiconductor sell-off, per Schwab.
- Qualcomm and Arm, Wednesday. Both depend on smartphone volumes, so their forecasts show how deep the squeeze goes on the consumer side (Schwab’s earnings calendar).
- Memory price updates. TrendForce says the pace of contract price increases is slowing even as prices rise, so the next bulletins matter more than the headline level.
- Friday’s jobs report. A weaker consumer makes it harder for device makers to pass costs on. We covered that story in Next week’s bigger vote is Friday’s jobs report, not Tuesday’s ballot.
How we see the future
Good case. Cloud spending stays strong enough to keep suppliers disciplined, while the pace of price increases keeps slowing, as TrendForce already expects. Device makers pass on costs, buyers adjust, and unit sales stabilize in 2027. Margins stay lower but stop falling.
Likely case (our view). Memory stays expensive through the holiday quarter and into next year, as Apple has said, and device makers with less pricing power report thinner margins and weak volumes. Memory suppliers keep their pricing power, which TrendForce says they hold today. Tech earnings keep splitting into winners and payers, and the market keeps treating them differently.
Bad case. The AI spending that created the shortage levels off before suppliers finish adding capacity, which is how the 2018 boom ended. Customers hold too much inventory, prices turn down fast, and the supplier side takes the hit that device makers took first. Consumers, who are already buying fewer devices, do not arrive in time to absorb the surplus.
What would change our mind. We would be less worried about device makers if contract price increases flatten sooner than TrendForce expects, or if phone and PC shipments recover without discounting. We would be less confident in the memory suppliers if cloud companies cut spending plans, if inventory builds at buyers, or if the open spot market keeps stalling while contract prices still rise, which TrendForce says is happening now.
Our take
A shortage is a transfer of profit from the buyers of a scarce thing to its sellers, and Apple’s report shows that transfer happening inside technology itself. History says it reverses, usually later than buyers hope and harder than sellers expect. We are watching for the first sign of that turn rather than predicting its date. This is our opinion for education, not a recommendation about any stock.
