The money is moving faster than the costs
The clearest verified evidence that AI demand is straining the memory supply chain is in Micron Technology's SEC filings. Its capital expenditure, the money spent on factories and equipment, was $7.676 billion in fiscal 2023 and $8.386 billion in fiscal 2024.1 In fiscal 2025 it reached $15.857 billion.1 That is about 1.9 times the prior year, so the company spent in one year almost as much as the previous two years combined.1
The quarterly figures show the same pattern. First-quarter capex was $1.796 billion in fiscal 2024, $3.206 billion in fiscal 2025 and $5.389 billion in fiscal 2026.1 That is about three times the level of two years earlier.1
Cost of revenue, the direct cost of making what Micron sells, rose far more slowly. It was $16.956 billion in fiscal 2023, $19.498 billion in fiscal 2024 and $22.505 billion in fiscal 2025.1 That is a rise of about 15% in the latest year, against nearly 90% for capex.1 Quarter on quarter, cost of revenue was $5.361 billion in the first quarter of fiscal 2025 and $5.997 billion a year later. For the second quarter it was $5.090 billion, then $6.105 billion.1 Those are increases of about 12% and 20%.1
The gap matters for a plain reason. A company that spends this much more on building capacity than on producing goods is betting that demand will stay high for years. It is also spending ahead of the revenue that would pay for it. Our dossier has no revenue or profit figures for Micron, so we cannot say how much of the spending is already paid for by sales. We can say how the company has funded it: from a growing cash balance.
A balance sheet that keeps filling up
Micron's cash was $8.577 billion in the third quarter of fiscal 2023, then $7.594 billion in the same quarter of 2024 and $10.163 billion in 2025.1 In the third quarter of fiscal 2026 it stood at $24.995 billion.1 That is about 2.5 times the figure a year earlier, and it is up from $13.908 billion just one quarter before.1
Putting capex and cash side by side, Micron's fiscal 2025 capex of $15.857 billion was about 1.6 times its year-end cash of $9.642 billion.1 By the third quarter of fiscal 2026, the cash balance alone was more than the whole of fiscal 2025 capex.1 The company is building a cushion while it spends heavily. The dossier does not say where the extra cash came from, so we do not speculate on it.
This helps explain why buybacks are part of the story. Under CHIPS Act restrictions, our event record says Micron is technically eligible to restart stock buybacks, but analysts are not necessarily expecting an announcement.2 A buyback would mean the company spending cash to buy its own shares. Whether it does so is a choice between that and the building programme above.
The analyst view, and how much weight it deserves
The most quoted bullish signals come from one research firm. Lynx Equity Strategies rates Micron "a clear buy with anticipated upside of 33%" and says the same of Sandisk, with anticipated upside of 49%.3 These claims come from a Motley Fool article about ASML's 4% rise on the day.3 Our measured reliability for that source is low: only 22% of 18 checked claims held up.3 The sample is small, but treat the targets as one firm's opinion, not as verified data. A price target is a forecast, not a fact, and none of the SEC figures above depend on it.
Locking in supply: the alliances
If memory is scarce, the buyers try to secure it. Nvidia's Raj Mirpuri said the Nvidia–SK Hynix expansion "will include a co-develop opportunity for us on the next-generation SK Hynix AI memory, and this will help us secure a stable supply of HBM memory."4 HBM is the high-bandwidth memory used alongside AI processors. The same article says roughly $950 billion in new AI agreements were signed at a South Korea summit in San Francisco on July 24.4 We cannot put that figure in a familiar context from our data. The source is mid-range on our reliability measure, with 56% of 4,959 checked claims holding up.4 The $950 billion is therefore a reported headline total, not a verified one.
Moving data is the second bottleneck
The squeeze is not only about memory chips. It is also about moving data between them. Bull and Kalray announced on July 28 a collaboration on networking technology for AI and high-performance computing, including compatibility with Ultra Ethernet, a new open standard.5 Kalray's Éric Baissus said the agreement confirms the relevance of the company's technological vision.5
GlobalFoundries signed a letter of intent with the U.S. Department of Commerce for a $300 million award to accelerate silicon photonics, the optical technology that moves data using light.6 A letter of intent is not a final award. AMD's Mark Papermaster said: "As AI systems scale, moving data efficiently is as critical as increasing compute performance."6
Consolidation continues elsewhere in the sector. Skyworks and Qorvo have announced the expected leadership team for their combined company, effective once their pending transaction completes.7 Both press releases come from a source where only 32% of 2,928 checked claims held up.5,6 That is typical of company-issued announcements, which we can confirm were made but whose claims should be read as the company's own account.5,6
A small-cap look at the same boom
Solitron Devices is a tiny chip supplier, but its quarter shows how uneven a boom can be. Net sales rose 101% to about $5.44 million in its fiscal 2027 first quarter, from $2.70 million a year earlier.8 Net bookings fell 48% to $1.45 million, while backlog rose 28% to $23.34 million.8 Falling new orders next to a growing backlog is a mixed signal. The company says it expects sales to continue "at this level or greater for the remainder of the 2027 fiscal year."8 That is a company projection.
The efficiency angle: chips that waste less heat
Hannah Earley, cofounder and CTO of Vaire Computing, argues that waste heat is "a design choice," in the paraphrase of MIT Technology Review, which describes her approach as reversible computing.9 She says: "I want to tackle every part of how computers are built, and rethink it in these terms."9 The idea is early-stage. Our reliability measure for that source is 0% of 11 checked claims, a very small sample, and the piece is a profile and not a financial disclosure. Zeta, a marketing-software company, announced on October 8 that it has begun development of a specialised AIM chip with partners, in what it calls a capital-light approach.10 That is a company statement and we have no financial detail on it.
Insider selling, in context
Lattice Semiconductor's SVP of Strategy and Marketing, Esam Elashmawi, reported selling 16,773 shares at a weighted average price of $134.56 per share, about $2.3 million in total, according to an SEC Form 4 filing.11 One insider sale does not tell you much, since executives sell for many personal reasons. We mention it only because it is a verifiable, filed transaction in a sector where most of the bullish noise is not. The Motley Fool source carries the same low reliability score as above, so the original SEC filing is the better reference.11
What Via News's analysis suggests
Via News's narrative analysis groups these items under a single theme: AI demand is creating a chip and memory shortage that the data suggests could last 12 to 18 months, pushing consolidation, supplier alliances and specialised chip designs.12 It also lists growing regulatory and geopolitical friction, including FTC scrutiny of AI agents, OpenAI's copying accusations against Moonshot, Chinese espionage targeting AI experts and China's YMTC expanding NAND capacity.12 This is our analysis, not an external fact. The dossier gives no sourced detail on the shortage's length or on those friction points, so we do not weigh them further. The one part we can fully check is Micron's balance sheet, and it shows a company spending and saving at the same time.
As for whether you already own this exposure: the dossier does not say how much Micron or the other names make up of any index fund. If you hold a broad technology or semiconductor fund, check its holdings list directly.
What to watch
- Whether Micron's capex keeps climbing faster than its cost of revenue. If cost of revenue starts to catch up, the spending is hitting production costs.
- Whether Micron announces a buyback, and how the size of the cash pile changes next to capex.
- Whether the GlobalFoundries letter of intent becomes a final award.
- Whether Solitron's falling bookings reverse or its backlog is worked through as sales.
