Monologue: The AI Data Center Overbuild

Sep 25, 2026 · 10m

Summary

The host investigates a massive AI infrastructure overbuild, revealing that approximately 50% of sold GPUs are currently warehoused or in unpowered data centers rather than active service. By analyzing "construction in progress" balance sheets, the episode estimates that $400–$500 billion in hardware is stalled, contradicting hyperscaler claims of rapid capacity expansion. The host argues that perceived scarcity is an illusion created by OpenAI and Anthropic absorbing most available compute, leading to an unsustainable bubble worse than the dot-com era.
