Every quarter, institutional investors with $100M+ in assets must file Form 13F with the SEC. ARK Invest's Q1 2026 filing reveals exactly what Cathie Wood held at the end of March — here's the complete breakdown.
A 13F is a quarterly report filed with the SEC by institutional investment managers. It discloses all equity holdings — giving retail investors a window into what the big players own. ARK Invest files 13Fs for each of its ETFs.
Important caveat: 13Fs are filed up to 45 days after quarter-end. The Q1 2026 filing (covering positions as of March 31) is due by May 15, 2026. The data below reflects what we know from ARK's daily trade disclosures, which are more current than the 13F itself.
ARK added several new names during the quarter. New positions signal fresh conviction — Cathie Wood doesn't add small positions to test the water; she builds conviction and then enters.
