AI Capex Grows Up: $22bn Chip Loans, $2.4bn Private-Credit "AI Factories" and the Shift from Equity to Secured Debt

September 2026 confirmed the financing pivot in AI infrastructure. A ten-bank syndicate lined up a $22bn chip loan for the Blackstone-Alphabet venture Crux AI, Blue Owl led a $2.4bn facility for IREN's AI factories, and Zankore signed up to $3.1bn. Equity still funds the platforms; secured debt now funds the machines.
On 16 September 2026 Bloomberg reported that a syndicate of ten banks was assembling a $22bn loan secured against chips to back Crux AI, the cloud venture formed by Blackstone and Alphabet. Two weeks earlier, on 28 August, Blue Owl Capital led a $2.4bn debt package for IREN Limited's AI factory buildout — described as the year's largest single-borrower private-credit facility tied specifically to AI infrastructure. Blue Owl reported $319bn of assets under management as at 30 June 2026.
The pattern extends beyond North America. On 9 September, Zankore — the neocloud platform backed by Ooredoo and Indosat — signed a senior term loan of up to $3.1bn to fund an Nvidia-powered GPU rollout across Indonesia and Southeast Asia. Equity has not disappeared: Crusoe raised a $3.9bn Series F on 17 September at a $30.9bn post-money valuation, co-led by Atreides, Mubadala Capital and Valor Equity Partners, with Nvidia, QIA and GIC participating.
What changed is the division of labour. Through 2024 and 2025, GPUs were bought with equity because nobody could underwrite their residual value. In 2026 lenders have accepted three things: that hyperscaler offtake contracts are bankable, that GPU depreciation schedules are estimable, and that the physical asset — chips, power interconnect, shell — can be perfected as collateral. IREN's delivery of its Horizon 1 facility to Microsoft on 13 August, and its Nvidia "Exemplar Cloud" status on the GB300 NVL72 platform, are exactly the contractual and technical evidence a credit committee needs.
The consequence is a materially lower blended cost of capital for anyone with a contracted offtake, and a materially higher barrier for anyone without one. A developer holding signed hyperscaler demand can now fund 60-70% of a project with secured debt; a speculative builder still funds close to 100% with equity. That gap, not chip availability, is what will determine which platforms survive the next capex cycle.
For mid-market companies the transferable lesson is about contract quality rather than sector. Lenders financed these assets because the cash flows were documented, the counterparties were investment grade and the collateral was identifiable. The same three tests decide whether a €20m European growth financing prices at 400bp or 700bp — and they are answered in the data room, not in the pitch.
Key takeaways
- $22bn chip-secured loan from a ten-bank syndicate backing Blackstone and Alphabet's Crux AI (reported 16 Sept 2026)
- Blue Owl led a $2.4bn facility for IREN's AI factories on 28 Aug 2026 — the year's largest single-borrower AI private-credit deal
- Zankore signed up to $3.1bn (9 Sept); Crusoe raised a $3.9bn Series F at a $30.9bn valuation (17 Sept)
- Contracted offtake now funds 60-70% with secured debt; speculative capacity still funds close to 100% with equity
