What is the HDI?
The Hyperscale Deficit Index (HDI) is a institutional macroeconomic benchmark measuring the thermodynamic and financial sustainability of global AI compute capacity.
By mapping real-time spot market rental rates directly against physical hardware operating costs, the HDI isolates true valuation from market speculation. A positive score denotes sustainable cash flow; a negative score indicates a debt-leveraged deficit expansion.
How It Is Calculated
The index engine extracts raw physical operational costs, combining commercial electricity tariffs, thermodynamic cooling penalties, and dynamic hardware depreciation, and contrasts them against market spot rates.
To ensure high institutional integrity, off-balance-sheet SPV debt structures are mathematically isolated from vendor-financed revenue recycling, presenting an unmanipulated baseline cost cross.
