ARK bought 277,573 shares of RKLB for ARKK on 22 September 2026: 0.21% of that fund — roughly $20.0m at that day’s close. ARK put the same trade in ARKQ and ARKX the same day, so this was a view across the shelf rather than one fund’s adjustment.

The entry above is RKLB’s close on 22 September 2026, $71.98. ARK discloses the fund, the date, the direction and the share count — never the price it paid — and the notification is published after the close, so this is the closing print on the day they traded rather than their fill, and the first moment anyone reading could act on it was the next open.

ARK’s most recent published holdings, as of the 21 September 2026 close, put ARKK’s position at 1,435,548 shares of RKLB — 1.03% of the fund.

ARK’s file covers portfolio adjustments the investment team made; it excludes the creation and redemption activity that moves an ETF’s share counts without anyone deciding anything.
