Chamath: banning open-source AI in the US could tank the stock market
rohanpaul_ai · x · 2026-09-28
Investor Chamath Palihapitiya argues that banning open-source AI in the U.S. risks tanking the stock market.
His reasoning: companies would be forced onto closed models costing 50–100x more, crushing earnings and valuations. Closed-model providers would gain U.S. revenue, but the market overall would lose value as model costs eat into corporate profitability.
The comments add another high-profile voice to the debate over potential U.S. restrictions on open-source AI.
