AI compute cumulative spend must grow 5-10x vs cloud before oversupply, says LeClerc

Responding to AI compute glut fears, Rob LeClerc notes cumulative AI DC spend is still below cumulative cloud spend since 2015. But (i) AI is far more compute-intensive, and (ii) builders pay a 30-40% scarcity/inflation/speed premium — $500B today buys what $300B did in 2024. His conclusion: cumulative AI compute spend probably needs to reach 5-10x cloud before oversupply, by which time demand drivers could be far bigger. Attached chart: estimated US data center cumulative capex 2015-2026, total $1.646T, AI $786B vs non-AI $860B, with AI share spiking in 2025-26.
