A lot of ink has been spilled on GPU financing lately. I spent over a decade trading ABS on Wall St, and structured over $2B+ of debt financings as an operator (including at @tryramp). Figured I'd try to make sense of this market, so I went back to a framework I knew well: aircraft ABS and aircraft engine ABS. My take: a GPU neocloud runs on airline economics, and the debt behind it looks a lot like aircraft engine ABS. The parallels: • Perishable inventory. An empty seat after the door closes is gone forever. So is an idle hour on an energized H100 rack. • 85%+ of cost is fixed (servers, 10-year rack leases, 10-14% debt service). One more hour of compute costs pennies of power. • Utilization is everything. Airlines break even around 80% load factor, a levered GPU cluster around 65-75%. The returns live in those last 25 percentage points. • NVIDIA is Boeing and Airbus rolled into one. Powered shells and grid interconnects are the new airport slots. • Wall St copied the aircraft financing playbook: take-or-pay contract plus servers in a bankruptcy-remote SPV, 70-80% LTV. Part 1 of my blog post goes into a lot more detail:
