Institutional owners (13F) 697 filers · $9.1B 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
100 (-21 vs prior Q)	54 (+7 vs prior Q)	191 (-12 vs prior Q)	238 (+52 vs prior Q)	+3.4M

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.
