Wood also bought shares in two flying taxi companies. ARK purchased 162,270 shares of Joby Aviation through the ARK Space Exploration & Innovation ETF for $2.5 million. The purchase came after Joby bought a 700,000-square-foot manufacturing facility in Dayton, Ohio.
The facility will be used to produce electric air taxis. These aircraft are also called eVTOL aircraft. Joby stock dropped 1.9% on the day of ARK’s purchase.

ARK Sells Palantir Stake
On the selling side, ARK dumped $10.4 million in Palantir Technologies. The fund sold 58,741 shares of the AI software company. This happened as President Donald Trump proposed a $1.5 trillion defense budget by 2027.
The proposed budget represents an increase from current spending levels. Palantir gets much of its revenue from government contracts for AI services. However, Palantir stock dropped 2.7% on January 8.
ARK also reduced positions in defense and space companies. The fund trimmed stakes in Aerovironment, Rocket Lab, and Kratos Defense. These sales were smaller than the Palantir transaction.
Wood separately sold $2.29 million in Roku stock on January 7. ARK offloaded 20,203 shares of the streaming platform company. This came after Roku gained 10% in the past month.
Roku posted a 42% gain in 2025. The stock outperformed the S&P 500 last year. Even after the sale, Roku remains a top holding in ARK Innovation ETF.
ARK Innovation gained nearly 38% in 2025. The fund benefited from gains in AI and software stocks. Wood’s investment approach focuses on disruptive technology companies.
The January 8 trades show Wood buying during price declines in chip and aviation stocks. She sold positions in companies that had recent gains or faced market pressure.
