Cathie Wood’s ARK Invest made a big move on Friday, June 13, 2026. The firm bought 3,291,184 shares of SpaceX across four of its ETFs on the same day the company made its Nasdaq debut.
The total value of the SpaceX purchase came to $444,309,840. The position was split across the ARK Innovation ETF, ARK Autonomous Technology and Robotics ETF, ARK Next Generation Internet ETF, and ARK Space Exploration and Innovation ETF.
Space Exploration Technologies Corp., SPCX
SpaceX was already ARK’s largest holding in its Venture Fund, making up over 11% of net assets — ahead of OpenAI and Anthropic.
ARK first invested in SpaceX through its Venture Fund in late 2023, when the company was valued below $200 billion. SpaceX now carries a market cap of $2.11 trillion.
SpaceX IPO Breaks Records
The SpaceX IPO raised $75 billion from the sale of 555.6 million shares. That makes it the largest public market debut in history.
In ARKX, the SpaceX position became one of the fund’s top holdings on day one, representing 6.89% of the fund.
ARK has long backed SpaceX’s model. “The company’s ability to re-use rockets results in structurally lower launch costs than competitors that will prove difficult to match,” the firm wrote in its investment thesis.
ARK Sells AMD and Rocket Lab
To make room for SpaceX, ARK sold shares across a wide range of companies.
On the same day as the SpaceX purchase, ARK sold 80,536 shares of Advanced Micro Devices across its ARKQ, ARKW, and ARKX ETFs. That sale totaled $39,337,809.
ARK also trimmed its Rocket Lab position across ARKQ and ARKX. The sale totaled $5,824,625.
The timing of the Rocket Lab sale stood out. SpaceX’s own S-1 filing named Rocket Lab as a direct competitor, describing it as a company expanding from small-lift into medium-lift payloads.
The day before, ARK had already sold shares in 20 companies totaling $222.87 million. The largest was Teradyne at $76.6 million. Twist Bioscience, Iridium Communications, and Robinhood Markets were also trimmed, totaling $64.2 million.
Other sales included shares of Tesla, Baidu, Roku, CrowdStrike, Cloudflare, and Veracyte.
ARK sold 98,835 shares of Roku for $11,824,619 and 39,850 shares of Tesla worth $15,906,127.
The two-day selling spree cleared space across ARK’s ETFs for the SpaceX position, which is now one of the firm’s largest public equity holdings.
