Cathie Wood
ARK Investment Management is led by founder, chief executive and chief investment officer Cathie Wood, who has final responsibility for investment decisions. Its research focuses on disruptive innovation, including robotics, genomics, financial technology and next-generation internet businesses. Analysts study technological change across traditional sector boundaries, then examine individual companies and valuations to build portfolios around those themes. ARK also publishes research and invites outside input into its process. Its identity is strongly tied to expectations about how new technologies will develop and spread.
On June 30, 2026, ARK Investment Management held 189 positions in US-listed stocks worth $15.4 billion. The ten largest were 39.4% of it.
The other 139 positions, worth $2 billion (12.9% of the total), are in the filing.
1 of the 189 positions have no US ticker in our data, so they are listed under the company’s name.
Options · 1 line
Listed as filed, as the number of shares each option is on. A put can be a bet against a stock or insurance on shares the fund holds, and the filing does not say which, so options are never added into the total above.
A 13F is a partial picture. Here is the part that is missing.
It lists long positions in US-listed stocks and options only. Not short positions, cash, ordinary bonds, anything listed only abroad, anything private, or anything bought and sold inside the quarter.
A quarterly SEC filing where large investment managers list the long positions in US-listed stocks and options they held at the end of the quarter. It is a snapshot, filed up to 45 days after that date.
Managers have 45 days after each quarter ends to file, and most of the funds we track file on the last permitted day. So the newest list still describes where the fund stood weeks ago, and the market has moved since.
How many equal-sized positions would be exactly this concentrated. Ten positions of the same size behave like 10. Ten positions where one holds most of the money behave like fewer than 2. It is 1 divided by the sum of each position’s squared share of the total.
Each line is one security as the manager filed it. Two share classes of one company, or a company’s stock and its convertible notes, are separate lines in the filing, and they stay separate here.
