Institutional owners (13F) 301 filers · $2.2B 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
109 (+37 vs prior Q) 27 (+12 vs prior Q) 86 (+26 vs prior Q) 72 (+13 vs prior Q) +3.9M

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.
