The clearest sign that the AI chip shortage is real money, and not only a story, is in a regulatory filing. Micron Technology spent $15.857 billion on capital expenditure (the factories and equipment that make chips) in fiscal 2025, up from $8.386 billion in fiscal 2024 and $7.676 billion in fiscal 2023.1 Spending was roughly flat for a year and then nearly doubled. This article starts with what a memory maker is doing with its own money, because that is the part we can check against SEC filings. The forecasts come after.
The spending: a company building for demand it expects to last
The quarterly figures show the same shape. Micron's capex in the first quarter of fiscal 2024 was $1.796 billion, in the first quarter of 2025 it was $3.206 billion, and in the first quarter of 2026 it was $5.389 billion.1 Spending is still accelerating, not levelling off at a new plateau.
The analyst view is that AI-driven demand is producing a chip shortage expected to last 12 to 18 months. That is Via News's tracked narrative of the sector, not a figure from a single filing.2 Spending like this is a bet that the shortage will run long enough to pay back the factories. Chip plants take time to build, so a company that expects a short squeeze would not commit this much.
The cash: a balance sheet that has changed size
Micron's cash was $8.577 billion at the end of fiscal 2023, $7.041 billion at the end of fiscal 2024 and $9.642 billion at the end of fiscal 2025.3 Over the last two reported quarters it moved much faster: $13.908 billion in the second quarter of fiscal 2026 and $24.995 billion in the third.3 A year earlier, the third quarter of fiscal 2025 showed $10.163 billion.3
To picture it, $24.995 billion is more than four times the roughly $5.7 billion that onsemi has agreed to pay for all of Synaptics (covered below).45 The filings do not say why cash rose so sharply, so we will not guess. The change is large enough that the balance sheet now looks very different from the 2023 and 2024 one, when the company held roughly $7 billion to $9 billion.
The costs: not yet a runaway
This is where the picture is less one-sided. Micron's cost of revenue (what it spends to produce what it sells) was $16.956 billion in fiscal 2023, $19.498 billion in fiscal 2024 and $22.505 billion in fiscal 2025.6 In the first quarter it was $5.361 billion in fiscal 2025 and $5.997 billion in fiscal 2026.6 In the second quarter it was $5.090 billion in fiscal 2025 and $6.105 billion in fiscal 2026.6
Costs are rising steadily, but they are not doubling the way capex did. Our dossier holds no revenue figures for Micron, so we cannot calculate profit margins and will not try. What the data does show is that investment is growing much faster than production costs. That fits a company building capacity ahead of sales, and it is the part that would hurt if demand softened.
What analysts are saying, and how far to trust it
Lynx Equity Strategies rates Micron a clear buy with 33% upside and Sandisk a clear buy with 49% upside.78 The comments were reported in a Motley Fool piece about ASML's stock rising 4%.7 The article says the bullish analysis set off a sympathy rally in related chip stocks.7
Two cautions. First, our own measurement of that source's reliability is low: only 22% of 18 checked claims from the Motley Fool material in our system held up.7 Second, an analyst target is an opinion about the future, while the capex and cash figures above come from SEC filings. A reader should weigh them differently. The same narrative lists SK Hynix among the memory beneficiaries, but we hold no verified financials for it, so we offer no numbers.2
A deal in the same coverage shows the other side of the demand story. Raj Mirpuri of Nvidia said the expansion with SK Hynix "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."9 A buyer of that size is working to lock in memory supply, which is what a shortage looks like from the customer's side. The source article carries a measured reliability of 57% of 4,956 checked claims, better than the Motley Fool material but far from perfect.9
Consolidation: smaller deals, shrinking prices
The same pressure is reshaping the rest of the sector. onsemi and Synaptics amended their June 25, 2026 merger agreement after an unsolicited competing proposal from a third party. onsemi will now acquire Synaptics for $123 per share in cash, an aggregate of about $5.7 billion, which our record says is down from a higher earlier figure of about $7 billion.5 The truncated event text leaves the reason for the lower price unstated, so we do not infer one.
Skyworks and Qorvo announced their expected combined leadership team on July 28, 2026. Bob Bruggeworth said the announcement "reflects the strong partnership that has shaped our integration planning efforts from the very beginning."10 On the same day, Bull and Kalray announced a collaboration on networking for AI and high-performance computing infrastructure. Éric Baissus said the agreement "confirme une nouvelle fois la pertinence de notre vision technologique" (confirms once again the relevance of our technological vision).11
GlobalFoundries signed a letter of intent with the U.S. Department of Commerce for a $300 million award to speed up silicon photonics, which moves data using light. AMD's Mark Papermaster said that "silicon photonics and advanced packaging will be key to delivering the bandwidth, energy efficiency, and system-level connectivity required for the next generation of AI cluster infrastructure."12 The award is a letter of intent, not a completed payment, and $300 million is small beside Micron's annual capex.
The search for different silicon
Our narrative tracking also flags a push for alternatives to today's AI chips: Apple's possible entry into enterprise AI servers, Google TPUs, Cerebras wafer-scale chips, and chip software work at DeepSeek and Huawei.2 None of these has verified financial data in our system, so they stay as signals, not figures.
The most concrete example is reversible computing. Hannah Earley, cofounder and chief technology officer of Vaire Computing, argues that waste heat is a design choice. She says conventional computing "is like racing through a city only to pump the brakes at every intersection," and wants to "rethink it in these terms."13 This is a research-stage idea, and the source's measured reliability is 0% of 11 checked claims.13 We report it as a direction of travel, not a proven business.
The friction: risks that can slow the cycle
The dossier lists several sources of geopolitical and regulatory risk. They include OpenAI's accusation on October 1, 2026 that China's Moonshot AI copied its models, reported Chinese espionage targeting AI experts, an FTC probe of AI agents and Pentagon AI programs.214 We hold no financial figures on how any of these would affect a chipmaker, so we cannot size them.
The edges of the story
Smaller defense-chip firms are mostly peripheral, but Solitron Devices is a useful reminder to read the whole report. Its net sales rose 101% to about $5.44 million in the fiscal 2027 first quarter, and backlog rose 28% to $23.34 million. Net bookings fell 48% to $1.45 million.15 The company expects sales to stay at this level or greater for the rest of the year.15 That source has a 30% measured reliability.15
On the insider side, Lattice Semiconductor SVP Esam Elashmawi reported selling 16,773 shares on Aug. 16 and 17, 2026 at a weighted average of $134.56 per share, about $2.3 million in total.16 A single executive's sale tells us little by itself, and the dossier gives no reason for it.
What to watch
- Micron's next capex figure. Quarterly spending has risen three years running. A flattening would be the first sign that the 12-to-18-month shortage view is being tested.
- Whether the cash pile is spent or returned. The jump to $24.995 billion raises the question of what it is for. The filings do not answer it.
- Cost of revenue against investment. If production costs start to rise as fast as capex did, margins will be squeezed.
- Whether the onsemi/Synaptics price holds at $123 per share and the competing proposal does not return.
- The sources. Every upside figure here comes from a source whose past claims held up less than 60% of the time, while the filings hold up fully. Weight them accordingly.
