Institutional owners (13F) 424 filers · $4.4B total · As of June 30, 2026

Institutions that report holding this stock in their quarterly SEC Form 13F. Long positions only; a single filer may appear twice for separate option legs. Large offsetting put/call legs typically reflect market-making or hedged inventory, not directional conviction.

Institutional activity — Q2 2026 vs prior quarter
New positions Exited positions Increased Decreased Net shares change
132 (+57 vs prior Q) 37 (-6 vs prior Q) 120 (+39 vs prior Q) 97 (-10 vs prior Q) +6.7M

Compared to Q1 2026. SEC Form 13F filings are due within 45 days of quarter-end plus a short buffer for late filers — quarters still inside that window are skipped in favor of the most recent fully-reported pair.
