ARKX — ARK SPACE & DEFENSE INNOVATION
As of Q2 2026, 12 SEC-registered investment managers reported holding ARKX (ARK SPACE & DEFENSE INNOVATION) in their latest 13F filings, with a combined reported value of $20.34M across 597.43K shares. That is +42.7% by share count (+178.90K shares) versus the previous quarter, while reported value moved +65.6%. Ownership is concentrated: the five largest holders account for 91.2% of reported value and the top ten for 99.7%.
Compared with the prior quarter, 6 opened new positions, 4 added to existing stakes, 1 trimmed. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.
All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
