Nobody knows what a used GPU cluster is worth
TLDR Dev 4 days ago
xAI's $5 billion GPU cluster (Colossus) serves as collateral for debt financing arranged by Apollo Global Management, but lenders cannot reliably assess its actual value because operational expertise lives with personnel, not in documented systems. GPU failure rates run at 9% annually, and clusters require specialized operations teams to manage failures, silent data corruption, and thermal issues that rarely appear in standard monitoring. The 6-7 percentage point premium charged on GPU-collateralized debt reflects uncertainty that has no equivalent in aircraft, shipping, or real estate financing, where standardized pricing and secondary markets exist after decades of maturation.
