13F Insight
What is 13F Insight?
Institutional investors managing over $100M must disclose holdings to the SEC quarterly, but parsing thousands of filings manually is impractical. 13F Insight ingests 380,000+ 13F filings, 4.3M+ insider transactions, and 480,000+ activist filings dating back to 1999. AI-powered Smart Money Alerts detect unusual patterns — massive new positions, complete exits, double-downs — and generate plain-language analysis. Ask questions in natural language, find consensus holdings across fund groups, or merge portfolios into one view. Free tier available, no credit card required.
How to use 13F Insight?
Browse 8,000+ institutional investors or search for any fund to see their full holdings, position changes, and AI analysis. Search any stock by ticker to see every institutional holder and insider trade. The homepage shows live Smart Money Alerts for unusual activity, and Pro users can ask questions in plain English or compare portfolios across multiple funds.
