Ark Invest divests from Amazon amid AI safety slowdown concerns

Cathie Wood's Ark Invest fund dumped Amazon shares on September 14, 2026, as leading artificial intelligence labs called for a development slowdown to address safety concerns. The sell-off occurred alongside moves into competitor Meta, and reflected broader investor concern about potential slowdowns in AI model advancement and the implications for earnings growth among heavy infrastructure spenders. The move contrasted with Ark's broader bullish stance from early September, when the firm had projected AWS could become a trillion-dollar-per-year business driven by AI monetization across enterprise and consumer interfaces.

2. The selloff came after leaders from Anthropic, OpenAI, and SpaceXAI published calls for AI development to slow pending better safety frameworks.
3. OpenAI CEO Sam Altman expressed support for slowing frontier model advancement and announced the company was delaying its 2026 IPO due to unresolved safety concerns.
4. Ark bought Meta shares on the same day, indicating a shift in AI infrastructure positioning within the fund's portfolio.
