The AI tape splits along balance sheets
The first thing to break in a vendor-financed buildout is the middleman who owns the assets and none of the cash flow, and equities are now pricing that layer separately from the rest.
Friday's session was flat at the index level — the S&P moved 0.03%, VIX 14.59 — and violent underneath it. IREN fell 9.7%, Nebius 4.9%, Applied Digital 4.7%, Core Scientific 4.0%. Over five days IREN is down 12.6% and Core Scientific is 29% below its recent high. In the same session Microsoft closed at its period high, Amazon rose 1.5%, Alphabet 1.0% and Meta 1.7%, taking it up 5.6% on the week. The dividing line is not who builds data centres. It is who pays for them. The hyperscalers fund from operating cash flow and investment-grade bonds — expensive bonds, at roughly 55 basis points over other US corporate credit, which JPMorgan's Matthias Reschke calls a "material premium", but bonds that clear (Bloomberg). The neoclouds fund with secured paper against the machines. Nebius upsized its raise to $5bn this week — reported as $3bn of convertibles due 2030 and $2bn due 2034 — after a $775m July loan backed by existing GPUs and the cash flows from one investment-grade customer, and has begun collateralising infrastructure and customer contracts for further borrowing. Applied Digital is sounding out roughly $3.5bn of high yield for its Delta Forge 1 campus in Louisiana. That model needs two things: a residual value for used GPUs, and a buyer for compute nobody has yet contracted. Nvidia's paused rent-back programme was, briefly, the answer to the second (Reuters). It is gone. The equity market appears to be marking that withdrawal before the credit market does: high yield sits at 267bp and has tightened 7% in twenty days.
