ARK Invest sold roughly $163 million in stock on Monday, June 16, 2026, to fund continued purchases of SpaceX shares after the company’s record-setting IPO debut four days earlier, according to the firm’s daily trading records and Investor’s Business Daily.
The sales marked the second major liquidation in a week for Cathie Wood’s investment firm. Last week, ARK Invest had sold an estimated $327 million worth of stock ahead of SpaceX’s IPO on June 12, then immediately deployed capital into the rocket company on its first trading day.
SpaceX priced its IPO at $135 per share on June 11, 2026, and opened trading at $150 on Friday, June 12, before closing at $160.95—a gain of nearly 20% on its debut, according to Reuters and Forbes. ARK Invest acquired 3.29 million shares of SpaceX that day, building a stake worth over $500 million, as reported by CoinDesk and Barron’s.
The largest single sale on Monday was 665,136 shares of Roku worth at least $77.7 million. The streaming platform’s stock had surged 20% the prior day after Fox Corporation announced a $22 billion acquisition deal, according to Investor’s Business Daily. ARK Invest also sold 141,408 shares of Advanced Micro Devices (AMD) worth a minimum of $23 million and 534,967 shares of 10x Genomics valued at least $15 million, the same source reported.
The majority of the sales came from the ARK Innovation ETF (ARKK), which shed roughly 2.3 million shares worth $143.4 million. The ARK Autonomous Tech & Robotics ETF (ARKQ) sold half a million shares valued at $13.8 million, while the ARK Space & Defense Innovation ETF (ARKX) divested 292.1 million shares worth $6.2 million, according to ARK Invest’s records cited by Investor’s Business Daily.
SpaceX now represents a significant portion of ARK Invest’s space-focused holdings. The company accounts for 4.3% of the ARK Innovation ETF’s roughly $7.3 billion in net assets, 6.25% of the ARK Autonomous Technology & Robotics ETF, and 7.19% of the ARK Space & Defense Innovation ETF, according to the firm. The rebalancing reflects Wood’s long-standing conviction in Elon Musk’s ventures—ARK Invest held a stake in SpaceX when it was still private through its venture fund, and maintains major positions in Tesla across its ETFs.
The pattern of selling other holdings to fund SpaceX purchases underscores the active management approach ARK Invest employs. The firm’s thematic strategy focuses on disruptive innovation across artificial intelligence, robotics, energy, blockchain, space, and biology, according to its Big Ideas 2026 research report released in January. The rebalancing activity, while unusual in its intensity, aligns with how actively managed ETFs adjust their portfolios to pursue their investment thesis.
