My early-warning layer: CoreWeave guiding $31-35B capex on $12-13B revenue — roughly 3x, funded by $25.1B debt, Microsoft about two-thirds of revenue; CFO's own framing: "CapEx shows up before revenue." Nebius more extreme: $20-25B capex on ~$3B revenue, capacity "sold out," anchored by Microsoft and Meta contracts, though cushioned by ~$9.3B cash. Oracle running -$23.7B FCF to fund a backlog-driven build. None distressed today; all fragile by construction. These are the balance sheets that would strain first if contracted demand slips.
From the best seats, the course confirms the buyer: power — not capital or chips — gates gigawatts, and memory bandwidth, not raw compute, is the wall. It refines with 20-year take-or-pay contracts and optical circuit-switching. It oversells where incentives predict: 'uncapped demand' is a token-seller's claim, the 2027-28 memory-glut counter-case goes unspoken, and the 'advanced packaging' layer has zero packaging content across twelve lectures. Clearest signal: insiders with opposite books describing the same market differently.
Look, you know, our filings show the concentration you're describing — top ten at 46% of revenue last quarter, up from 40% and 41% the two years before. Quite frankly, one customer over 10%, different one than a year ago, and we can't name any of them. It's the component supplier shape: revenue climbing while the buyer list narrows. We'll see how it tracks.
