The Net Zero Thesis

The Net Zero Thesis is Damodaran's controversial counter-narrative to the dominant AI investment story. His claim, articulated repeatedly in 2024-2026 interviews and blog posts, is that the aggregate market impact of AI will be approximately neutral — not because AI is unimportant (he considers it genuinely revolutionary, a view he updated after watching ChatGPT) but because the gains accruing to AI winners will be approximately offset by losses among AI losers and capital misallocated during the Big Market Delusion phase. The pattern is consistent across prior technology revolutions: PCs produced Microsoft and Intel but destroyed dozens of hardware companies; the internet produced Amazon and Google but destroyed hundreds of dot-coms; smartphones produced Apple but gutted Nokia and BlackBerry. "For those winners, there were dozens, even hundreds of losers," Damodaran observed. The net effect on aggregate market returns was modest in every case, even as individual winners produced spectacular returns.
