# Memory Is Eating the AI Boom

> UBS lifted 2026 AI capex to nearly $1 trillion, but non-memory spending actually falls next year while memory more than doubles: on the bank's own arithmetic, the boom's growth is mostly a component price, a transfer to Asia's chipmakers rather than US growth.

UBS now [puts AI capex at $998 billion this year, up from $506 billion in 2025, and $1.447 trillion in 2027](https://finance.yahoo.com/technology/ai/articles/ubs-now-expects-ai-capex-044549899.html) [1]. [Micron](https://theinference.org/markets/companies/micron) closed up 3.92% as the note crossed [1]. The headline says boom. The itemized bill says price.

## The 2027 increase is one component

UBS estimates memory spending climbs from $71 billion in 2025 to $367 billion this year and $923 billion in 2027, while all other AI spending falls from $631 billion to $525 billion [1]. Memory goes from 14% of the bill to 64%, and roughly 90% of the two-year increase is memory [1]. Every dollar of next year's growth is one line item getting more expensive.

*Chart: **Memory goes from 14% of AI capex to 64% in two years** Column chart of UBS AI capex estimates for 2025, 2026 and 2027: memory spending rises from $71B to $367B to $923B while all other AI spending goes from $435B to $631B and then falls to $525B*

*AI capital spending by component, in billions of dollars. 2026 and 2027 are UBS forecasts. [1]*

## Buyers pay twice in one week

The Fed raised rates to 3.75%–4.00% on 16 September, its first hike since July 2023, and sees policy near or above 4% through 2027 [2]. The biggest cloud spenders were already [putting 102% of cloud revenue into capex](https://247wallst.com/investing/2026/08/22/ais-absurd-spending-boom-hyperscalers-are-spending-102-of-cloud-revenue-on-capex/) [3].

On 1 October, [Nebius](https://theinference.org/markets/companies/nebius) [lifts on-demand GPU rates about 17%–21%](https://theinference.org/article/nebius-raises-hourly-gpu-rates-up-to-21-from-1-october), its second hike in three months, with server memory up 41% [4]. [CoreWeave](https://theinference.org/markets/companies/coreweave) said on 17 September it has kept contracting new compute capacity at higher prices, about $40 million per megawatt on short-dated deals [5]. Dearer chips, dearer money, same buyers.

## The margin moves to Asia

Korea's [DRAM export price hit $92,183 a kilogram in August](https://biz.chosun.com/en/en-it/2026/08/26/GGP4F4N5VVGNXPBOJ25PFM7PCE/), up 401% year on year and 12.5 times the January 2023 trough [6]. UBS says the price-driven share adds little to real US GDP and shifts income and profits toward memory producers in Asia [1]. SK Hynix holds about half of high-bandwidth memory [7].

## Nvidia and SK Hynix call the shortage structural

[Nvidia](https://theinference.org/markets/companies/nvidia) CFO Colette Kress calls memory pricing "extreme" and headed "even higher into next year" [7]. SK Hynix chief [Kwak Noh-jung](https://theinference.org/markets/people/kwak-noh-jung) [told Reuters in July](https://www.reuters.com/world/asia-pacific/sk-hynix-ceo-sees-worst-ever-memory-supply-shortage-2027-says-demand-outstrip-2026-07-10/) that 2027 will be "the worst year in the industry's history from the supply perspective," with demand above supply beyond 2030 [8]. Micron passed a $1 trillion valuation yet still trades at 6.6 times forward earnings [7]. The price-versus-volume split is the one number UBS does not give.

## The loss, if prices turn, is already contracted

Goldman sees the DRAM shortfall widening next year [6]; Citi alone in this story calls the peak, with DRAM and NAND prices topping out in the second quarter of 2027 and DRAM falling in the second half [9]. Micron has [locked its buyers into take-or-pay agreements through 2030](https://theinference.org/article/microns-100-billion-insurance-policy-has-a-deductible): binding volumes, guaranteed floors, roughly $100 billion of obligations backed by $22 billion in deposits [10]. If Citi's clock is right, the customers holding those commitments near cycle-top prices carry the loss.

## The midterms are targeting the wrong line item

Micron reports fiscal Q4 on 30 September into record prices [7]. The tell is the split UBS left blank: Micron's fiscal Q3 DRAM average selling price rose by the low-60% range in a single quarter [6]. If revenue steps up again while shipped bits barely move, the boom is price, not compute.

*Chart: **Micron added $32.2B of quarterly revenue in a year; $31.5B of it was gross profit** Grouped column chart of Micron's quarterly revenue and gross profit from Q3 2024 to Q2 2026 (calendar quarters): revenue rose from $7.75B to $41.46B and gross profit from $2.74B to $35.06B.*

*Calendar quarters, in billions of dollars; Q2 2026 is Micron's fiscal third quarter, the one whose DRAM prices rose by the low-60% range. [12]*

At least 15 state legislatures are [pushing data center restrictions before November's midterms](https://finance.yahoo.com/technology/ai/articles/ai-concerns-moved-center-midterm-085642768.html), though Citi sees no material damage to the construction pipeline yet [11]. The Inference [traced where the transfer lands on 18 September](https://theinference.org/article/the-same-ai-boom-is-making-taiwan-richer-and-south-korea-s-households-pay-more-to-borrow), from Taiwan's chip windfall to South Korean household borrowing costs. The politicians are campaigning against the buildings; the marginal dollar is in the chips.

## Takeaway

UBS's own line items show every dollar of next year's AI capex growth is memory getting more expensive, with all other AI spending falling in 2027. The gain lands with Asia's chipmakers, while US buyers pay for dearer chips and dearer money at the same time.
