  "summary": "This model quantifies positive feedback loops (data, compute, talent, network effects) driving AI market concentration, estimating combined loop gain of 1.2-2.0 means top 3-5 actors will control 70-90% of frontier capabilities. Analysis provides intervention cost-effectiveness estimates ranging from \\$3-10M per 1% HHI reduction (antitrust) to \\$200-500M (talent programs), with public compute infrastructure (\\$5-20B annually) offering highest leverage despite difficulty.",
