Self Driving Portfolio: 50 Specialized Agents Manage Institutional Assets With Voting and Self-Rewriting Code
arXiv·medium signal
BlackRock-affiliated researchers present an agentic asset allocation pipeline where ~50 specialized agents produce capital market assumptions, construct portfolios using 20+ competing methods, and critique and vote on each other's output. A researcher agent proposes new portfolio methods, and a meta-agent compares past forecasts against realized returns and rewrites agent code and prompts accordingly. The architecture demonstrates multi-agent self-improvement patterns applicable beyond finance.
