AI datacenters hit diseconomies of scale as inference shifts demand smaller

The post argues that datacenters face diseconomies of scale outside training.

As workloads shift toward inference, the author says the winning direction is smaller and faster infrastructure.

It quotes a detailed example about Oracle’s Wisconsin datacenter: the project has become a case study in how credit risk is priced into AI buildouts. Because We Energies’ tariff requires collateral from developers rated below A-, Oracle’s BBB- rating triggers a $7B letter of credit plus $100M+ per year in costs on a $15B, 1GW site tied to a $300B OpenAI contract. Wisconsin regulators declined to revisit the rule, and Oracle is now challenging it in county court.

The broader point is that many states are designing large-load tariffs to prevent ratepayers from absorbing stranded-asset risk from hyperscaler capex binges.
