ARK Investment Management’s 13F: what it reported owning at Jun 30, 2026
ARK Investment Management’s stock holdings as reported to the SEC for the quarter ended Jun 30, 2026, compared with the quarter before: top positions, new positions, exits and the biggest changes in shares.
The short answer
ARK Investment Management’s 13F for the quarter ended Jun 30, 2026 lists 190 stock positions with a combined reported value of $15.40B, compared with 181 stock positions worth $12.86B in its filing for the quarter ended Mar 31, 2026. The three largest positions were Tesla, AMD and Space Exploration Technologies Corp, together 17.8% of that value. Against the previous quarter, 16 positions are new, 7 positions are gone, the share count rose in 79, fell in 94 and did not change in 1. The filing’s total reported value, $15.40B, also includes 1 option position (puts and calls, reported by the number of shares underneath them), which are not counted as stock positions here.
What a 13F shows, and what it doesn't
A 13F is a quarterly report that large investment managers file with the SEC. It is a useful record and a limited one. Read this list before reading the tables.
- It is late. The filing is due 45 days after the quarter ends. This one covers the quarter ended Jun 30, 2026 and was filed on Aug 14, 2026, 45 days later. Whatever the filer did since quarter end is not in it.
- It is a snapshot of one day. A 13F shows what the filer held on the last day of the quarter. A stock bought and sold inside the quarter never appears, and a position built up over three months looks like a single change.
- It lists long positions in US-listed stocks and similar securities only. Short positions, cash, Treasury bills, most bonds, most foreign shares and private companies are left out, so the list is not the filer’s whole portfolio.
- Reported value is a quarter-end price times shares. When a value changes between two filings, part of the change is the stock price moving. The change in shares is the better sign of buying or selling, and even that does not say why.
- Some details can be held back. Filers may ask the SEC to keep a position confidential for a time. This filing says no positions were left out on that basis.
- The filing can cover more than one entity. This filing lists no other included managers.
- It is not advice, and it is not a model portfolio. A manager’s holdings reflect its own goals, costs, time frame and risk limits, and the positions may already have changed. Nothing here says what anyone else should own.
