These are ARK Space & Defense Innovation ETF's own holdings, not the firm's. Percentages are of the stock positions in its latest filing — the fund's cash and bonds are not included. This fund buys companies that push activity beyond the surface of the Earth and the firms that make that possible. It casts a wide net across four buckets: orbital aerospace (rockets and satellites), sub-orbital aerospace (drones and air taxis), enabling technologies such as artificial intelligence, robotics, 3D printing and batteries, and autonomous mobility. It launched in March 2021 as ARK's space exploration vehicle and was renamed in late 2025 to put defense innovation explicitly into its mandate, though the shift was mostly a label for contractors already in the portfolio. Where sibling ARK funds each chase one narrow theme, this one is a themed growth fund with an unusually broad reach, and it is actively managed rather than tied to an index. The managers look for the companies they expect to lead, enable or simply benefit from a growing space economy, which means its holdings can span anything from satellite operators to defense primes. It is run by Cathie Wood, the firm's founder and chief investment officer, alongside ARK's research team, using the same research-driven, concentrated style the firm applies across its lineup.
