The European angle is narrower than the headlines suggest
Two European names carry this story in our data. The first is ASML, the Netherlands-based company that prints circuits onto chips. It rose more than 4% on a Friday because a bullish note from the research firm Lynx Equity Strategies lifted related chip stocks in sympathy.1 The second is Kalray, listed on Euronext Growth Paris, which announced a collaboration with Bull on networking technology for AI and high-performance computing. The two companies will also work on compatibility with Ultra Ethernet, an open standard that may shape future supercomputer networks.2
Our dossier contains no EU regulation, no European industrial-policy measure and no European-listed memory maker. The public-money item in it is American: GlobalFoundries signed a letter of intent for a $300 million award from the U.S. Department of Commerce to speed up silicon photonics, a technology that moves data as light.3 The money behind this boom is overwhelmingly being spent elsewhere. Europe's role, as far as our data shows, is toolmaker and networking supplier.
What the checked numbers say: Micron is spending far more
Micron is a memory-chip maker, and its figures come from SEC filings, so we can state them plainly. Capital expenditure was $7.676 billion in fiscal 2023 and $8.386 billion in fiscal 2024.4 It then reached $15.857 billion in fiscal 2025, close to double the year before.4 For scale, that is about seven-tenths of the $22.505 billion it cost Micron to produce what it sold that year (our arithmetic).6
The quarterly figures show the pace picking up. Capex in the first quarter was $1.796 billion in 2024, $3.206 billion in 2025 and $5.389 billion in 2026, roughly three times the 2024 figure.4 Cost of revenue rose much more slowly over the same quarters, from $4.761 billion to $5.361 billion to $5.997 billion.6 On those filings, spending on factories and equipment is growing much faster than the cost of making today's products.
Cash tells a similar story. Micron held $10.163 billion in the third quarter of 2025 and $24.995 billion in the third quarter of 2026.5 The previous quarter's figure was $13.908 billion, so cash rose by about $11 billion in a single quarter (our arithmetic).5 One scheduled date matters here. Under CHIPS Act restrictions, Micron could technically restart stock buybacks from December 9, 2026. Analysts are not necessarily expecting an announcement.15
Upside calls, and how much weight they deserve
Lynx Equity Strategies rates Micron a clear buy with anticipated upside of 33%, and Sandisk a clear buy with 49%.1 That is one firm's view, reported through a Motley Fool article. Our measurements show only 31% of 58 checked claims from that outlet held up.1 The sample is small, but it argues for treating the price targets as opinion, not data. Our dossier does not say how much of Micron or ASML sits inside a typical index fund, so we will not guess at your exposure.
Suppliers report strong results, with caveats
Advanced Energy, which supplies power equipment, reported third-quarter 2026 revenue of $696 million, up 50% year over year and above the top of its guidance.7 Our topic summary describes growth of 64%. The event record for the report itself says 50%, so we use 50% and flag the discrepancy. Its fourth-quarter guidance is $735 million, plus or minus $25 million.7
Impinj, which makes RFID chips, reported record third-quarter revenue of $112.1 million.8 Its fourth-quarter guidance of $104.0 to $107.0 million sits below that record.8 Strong results and a softer next-quarter outlook can both be true at once.
Solitron Devices, a small defense-linked supplier, shows how uneven the cycle is. Net sales rose 101% to about $5.44 million, but net bookings fell 48% to $1.45 million. Backlog rose 28% to $23.34 million.9 The company expects revenue to stay at this level or higher for the rest of fiscal 2027.9 Our topic summary also notes slow procurement and a strategic review.17 Solitron's own results release says nothing on either point in the text we hold. Those two points rest on our summary alone.
Deals and consolidation
Nvidia is expanding its relationship with SK Hynix. Raj Mirpuri said: "The 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."10 The same report says roughly $950 billion in new AI agreements were signed at a July 24 summit in San Francisco.10 That is a headline figure for agreements, not money spent.
Skyworks and Qorvo announced the expected leadership team for their combined company, effective once the pending transaction completes.11 One insider sold shares in the same period. Lattice Semiconductor's SVP Esam Elashmawi reported selling 16,773 shares on Aug. 16 and 17, 2026, at a weighted average of $134.56 per share.12 A single sale like this says little by itself.
The longer bet: moving data, and wasting less heat
Mark Papermaster of AMD framed the bandwidth problem: "As AI systems scale, moving data efficiently is as critical as increasing compute performance."3 He argued that silicon photonics and advanced packaging will be key to the bandwidth and energy efficiency of future AI clusters.3 That is the same ground Kalray and Bull are working on from the European side.
Hannah Earley, 31, is cofounder and chief technology officer of Vaire Computing. Her startup builds chips that recycle energy normally lost as heat, an approach called reversible computing. She argues waste heat is a design choice, not an inevitable cost.13 She compares conventional computing to racing through a city and braking at every intersection, so the car must burn more fuel to speed up again.13 Of her resonator she says, "It's really a glorified pendulum."13 She also says: "I want to tackle every part of how computers are built, and rethink it in these terms."13 This is early-stage research, not shipping product. Our measurements show only 6% of 16 checked claims from this source held up, a tiny sample but a reason for caution.13
At the other end, edge-AI products are arriving. Harvest Praxis launched its "Hyper AI Brain" on October 22, 2026, an on-device computing platform on MediaTek's 3nm chip.16 Separately, Crunchbase says the 2026 IPO window is narrowing.14 Our topic summary says SambaNova is weighing a 2027 U.S. listing.17
What to watch
- Whether Micron's capex keeps outrunning its cost of revenue, and what it does with $24.995 billion in cash after December 9.515
- Whether Advanced Energy lands its $735 million fourth-quarter guidance.7
- Whether Kalray and Bull turn their collaboration into products built on Ultra Ethernet.2
- Whether Solitron's bookings recover to match its backlog.9
Source reliability here is mixed. The wire-style documents we cite score between 35% and 53% on our checks.210 Treat forecasts as claims to be tested, and the SEC-filed figures as the firmest ground.
