The buyers of the racks are getting weaker
Chip revenue is increasingly booked against buyers whose ability to pay depends on debt the seller has underwritten.
TrendForce estimates that the latest generation of high-end server rack systems (NVL72-class, including GB300, VR200 and VR300) will generate more than $710bn of value in 2027, a 214% increase, on shipment growth above 50% and a doubling of average selling price for the next-generation Vera Rubin chips. Buried in the same research is the number that matters more. The five big North American cloud providers' share of rack purchases is expected to fall from about 70% in 2025 to 60% in 2026, with the difference made up by Tesla (including xAI and SpaceX) and CoreWeave (TrendForce, via Newtalk). Read that as a statement about who can pay rather than who is buying. Microsoft, Amazon and Alphabet buy chips out of the cash their businesses generate. The replacement buyers do not. IREN is funding its next-generation chip purchases with $2.4bn from Blue Owl and Pimco at 9% interest, coming due two and a half years after the money is drawn (Bloomberg). Lambda has just raised about $1bn of short-dated private debt arranged by JPMorgan for chips that Microsoft will lease, weeks after a separate $926m loan (Bloomberg). Which is why the vendors are now writing the credit themselves: Nvidia's $105bn guarantee covering the residual value of the Ohio campus, Google's $44bn rent guarantee for Anthropic, and Broadcom's pledge to buy back chips that do not sell. When the buyer at the margin cannot carry the debt, the supplier carries it, and revenue growth and credit exposure become the same line. TrendForce is a forecaster, not a regulatory filing. Treat the 2027 numbers as an estimate. Treat the shift in who is buying as the point.
