Hello world, it’s Friday, October 23rd.
Meta spent $34.91 billion on CapEx in a single quarter, pushing free cash flow negative and sending shares down 7%. Elsewhere, TSMC is asking equipment suppliers to strip Chinese rare-earth magnets out of their tools, Tesla and Nvidia are funding dedicated FC-BGA lines at Samsung Electro-Mechanics, and SK Hynix pulled Solidigm’s $10 billion US listing.
Let’s get into it. — Austin & Vik

Presented by Crusoe
Crusoe builds the full stack for AI, from power and data centers to the cloud. It can also help you tune a small model on your own data for just a few bucks.
For repeatable work like reports, an open model trained on your terminology and formats can match a frontier model, and it’s cheaper and faster to run.
Crusoe’s Serverless Fine-Tuning handles the training: upload your dataset, pick an open model like Llama, DeepSeek, or GLM, and pay per million tokens used, not per GPU hour.
About $2 buys roughly 5M training tokens on smaller models.

Meta’s $34.9 Billion Quarter CapEx Sends Stock Sliding, Spreads Widening
Meta spent $34.91 billion on capital expenditures in a single quarter, blowing past analyst estimates and pushing free cash flow negative for the first time in years. Shares fell 7% on the report, dragging the Nasdaq lower with them. The company guided 2026 CapEx as high as $145 billion, a ceiling that Bloomberg reports drove Meta’s credit risk gauge to a fresh high as spreads widened on the spending plans. Beyond the quarterly figures, Meta disclosed $825 billion in total future spending commitments. The investor debate has visibly shifted: not whether AI infrastructure spend will arrive, but whether any monetization timeline can keep pace with a burn rate of this scale.
TSMC Asks Equipment Suppliers to Drop Chinese Rare-Earth Magnets
TSMC has formally asked chipmaking equipment suppliers to develop motors and components that contain no Chinese rare-earth magnets, the first known request of its kind directed at the tool level of the semiconductor supply chain. The move comes after Beijing tightened export controls on rare-earth materials, which are used in the permanent magnets inside motors that drive wafer-handling and lithography equipment. China currently dominates global production of those materials. TSMC hasn’t named specific suppliers, but the request spans broadly across its equipment base, according to Reuters sources. Redesigning motors around alternative materials is a multi-year undertaking, and replacing Chinese rare-earth components in fab tools will carry meaningful costs across the equipment ecosystem.
Vik: Permanent-magnet motors in the wafer handlers and litho stages run on neodymium and dysprosium, and China controls roughly 95% of the finished magnets. Alternatives exist - induction, switched-reluctance, ferrite - but requalifying motors across a fab’s entire tool base is a drawn-out slog.
Tesla and Nvidia Take Equity Stakes in Samsung Electro-Mechanics Substrate Lines
Tesla is committing KRW 1.1 trillion to secure dedicated FC-BGA substrate capacity at Samsung Electro-Mechanics, while Nvidia adds KRW 2.6 trillion in a parallel investment. The two companies aren’t writing checks to a middleman: they are co-funding dedicated production lines at Samsung Electro-Mechanics’ Sejong and Busan plants, giving each investor allocated output rather than a place in the standard order queue. Together the commitments total roughly KRW 3.7 trillion. FC-BGA substrates sit directly beneath AI accelerators and high-end automotive chips, making capacity here a hard constraint on how fast either company can ship finished silicon.
Vik: Ibiden still holds 70%+ of high-end FC-BGA, so the signal here is SEMCO buying its way up the share table on customer money. Nvidia’s running the same play with Ibiden prepayments and Unimicron reservations. Tesla’s allocation doesn’t even land until 2029 though.
SK Hynix Scraps Solidigm’s $10 Billion US Listing After Regulatory Opposition
SK Hynix has discontinued the IPO review for Solidigm, its US-based NAND unit, after Seoul authorities and shareholders pushed back against the planned listing. The deal had been valued at up to $10 billion and was intended to fund a new American fab to serve rising AI memory demand. Solidigm’s own statement cited “market conditions and share price trends” rather than regulatory friction, but Bloomberg reported strong opposition from Korean regulators and investors as the decisive factor. SK Hynix shares rallied on the news. The company says alternatives to finance Solidigm’s growth and generate shareholder returns remain under consideration, with no replacement mechanism named.
JCET Commits $2.73 Billion to Advanced Packaging After AI Lifts Margins
JCET, China’s largest outsourced semiconductor assembly and test provider, is deploying $2.73 billion into advanced packaging capacity after AI-driven demand pushed margins and revenue higher through the first three quarters of 2026. The expansion targets chiplet integration and heterogeneous assembly, technologies that put JCET directly in the path of ASE and Amkor as hyperscalers shop for next-generation AI SoC packaging contracts. The company’s Q3 YTD results showed steady revenue growth alongside improved profitability, with AI-related orders credited for the margin lift. JCET isn’t waiting for the cycle to mature before committing capital. The investment scale makes clear that China’s leading OSAT intends to compete at the top of the packaging value chain, not just fill capacity below it.
Short Sellers Bank $6 Billion as CoreWeave Debt Fears Spread Across Neoclouds
Short sellers have accumulated $6 billion in unrealized profits betting against CoreWeave and its neocloud peers as widening credit spreads and mounting debt concerns batter the sector. CoreWeave stock hit new 2026 lows alongside fellow neocloud IREN, with CoreWeave shares dropping nearly 10% after Nvidia’s CEO flagged an AI funding crunch. The structural problem is familiar: long-dated GPU lease commitments financed with short-term debt leave neoclouds acutely exposed when credit conditions tighten. Bloomberg reported that AI-sector credit spreads reached a 17-month high, amplifying refinancing risk across the group. Blackstone president Jon Gray told CNBC the company can “find a way through” the financing pressure, offering one of the few public defenses of the model’s durability.
