Names the most funds opened from scratch: fresh institutional bets.
Computed from the latest non-superseded 13F filing of every tracked fund as of Q3 2026, grouped by security (a 13F shows long positions only, on a quarterly lag). Pick any quarter above to see that point-in-time ranking. No look-ahead. All data is public domain, sourced to SEC EDGAR 13F. The same ranking is available programmatically via the Arkolith API & MCP server.
