ARK bought 166,585 shares of IONS for ARKG on 14 September 2026: 0.49% of that fund — roughly $8.6m at that day’s close.
The entry above is IONS’s close on 14 September 2026, $51.44. 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.
Also bought that session: META at 665.60 (0.40% of the fund), GH at 167.84 (0.35% of the fund), AVAV at 153.40 (0.32% of the fund). Each priced the same way — the close on the day ARK traded it.
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. Sales are not posted here: trimming a position is an exit, not a short. An automated tracker of public ARK Invest disclosures, not a recommendation. Not run by or affiliated with ARK Invest or Cathie Wood.
