OpenAI CEO Sam Altman says one of his biggest fears is that the most advanced AI capabilities could end up controlled by only a small number of companies or countries. In comments reported by Business Insider and echoed by Yahoo News, Altman frames the concern around gatekeeping: he says the risk is that access to advanced AI technologies could be restricted rather than broadly available. Altman’s position centers on the idea that concentration of control—whether among private firms or states—could limit competition, reduce openness, and shape how the technology is used. While the coverage focuses on his warning about concentration, it does not present specific policy proposals or identify which companies or countries he has in mind. Overall, the reports describe Altman emphasizing the potential downsides of centralized ownership and control over AI infrastructure and capabilities, describing such an outcome as “very, very bad.”
