Every quarter, institutional investors managing over $100M must disclose their holdings to the SEC. But parsing thousands of XML filings manually is impractical. 13F Insight automatically ingests and analyzes 380,000+ 13F filings, 4.3M+ insider transactions, and 480,000+ activist filings dating back to 1999, then surfaces the signals that matter.
The platform covers three major SEC filing types: 13F quarterly holdings for full portfolio views of any institutional filer, Form 4 insider transactions updated hourly, and 13D/G filings for tracking significant 5%+ ownership stakes. AI-powered Smart Money Alerts detect unusual patterns across these filings — massive new positions, complete exits, double-downs, and concentrated buys — and generate plain-language analysis for each event.
For deeper research, you can ask questions in natural language like "Which hedge funds bought NVDA last quarter?", find consensus holdings across fund groups, or merge multiple portfolios into a single combined view. Every filer is scored with WhaleScore™, a 0-100 quality ranking based on performance and credibility. Free tier with generous limits, no credit card required.
