ARK Invest, led by Cathie Wood, has made notable moves in its portfolio by selling shares of Palantir and AMD while increasing its stake in Archer Aviation. The trades were made through the ARK Innovation ETF on Sept. 8.
ARK sold 38,395 shares of Palantir Technologies worth about $6.5 million. It also sold 19,491 shares of Advanced Micro Devices worth about $9.9 million. At the same time, ARK bought 575,700 shares of Archer Aviation worth about $3.35 million.
The moves come as part of the firm’s active approach to managing its holdings. ARK publishes daily trade notifications for its actively managed exchange-traded funds. The company notes that the trade files are not comprehensive lists of every transaction because some activities such as offerings and ETF creation or redemption activity are excluded.
The firm has recently sold some of its holdings in Palantir and AMD, which Yahoo Finance described as portfolio trimming rather than clear evidence that ARK had abandoned its longer-term technology strategy. Palantir has been among the technology stocks that ARK has reduced while moving money into other companies. ARK also sold about $72.8 million of AMD shares in a separate trade in late August while buying Nvidia and Broadcom.
Archer Aviation, a company developing electric vertical take-off and landing aircraft, has drawn increased attention from the fund. The company recently entered into an agreement with Boeing to acquire several subsidiaries including Insitu, SkyGrid, and Wisk Aero. This acquisition could enhance Archer's role in the eVTOL market, drone technology, and autonomous flight systems.
The Boeing agreement goes beyond an asset sale. Boeing plans to take a stake in Archer and become a strategic partner. The companies also agreed to collaborate and share technology. Boeing will retain access to Wisk's autonomous flight technology for its own commercial and defense aircraft.
Insitu designs and builds uncrewed aircraft systems used for intelligence, surveillance and reconnaissance missions. Archer said the business currently generates more than $200 million in annual revenue and operates across 35 countries. Wisk has spent years developing autonomous eVTOL aircraft while SkyGrid specializes in airspace-management technology.
The transaction is expected to close by the end of 2026. It still must meet regulatory and other closing conditions.
ARK Invest's decision to boost its stake in Archer adds to an existing position in the aviation company. The Sept. 8 purchase came as Archer continued testing its Midnight aircraft and working toward commercial operations. Yahoo Finance reported that Archer had recently completed a piloted round-trip flight between Salinas and Hollister in California.
ARK continues to focus much of its research and investment strategy on emerging technologies. Its 2026 Investment Opportunity Report identifies artificial intelligence, autonomous technology and robotics, biotechnology, space and defense, and blockchain and financial technology as its five major areas of disruptive innovation.
ARK Invest’s approach shows a clear emphasis on innovation and long-term growth over short-term gains. This move aligns with the fund’s broader strategy of investing in companies that are shaping the future of technology and transportation.
The fund’s transparency in sharing its holdings and trades gives investors frequent information about changes in its portfolios. ARK says its holdings are updated at the end of every trading day.
The latest transactions show ARK reducing exposure to two established AI-related stocks while adding to an earlier-stage aviation company. The trades do not necessarily mean ARK has abandoned Palantir or AMD because the firm actively changes portfolio weights and can trade positions frequently.
Archer still faces major steps before its air-taxi business can operate on a large commercial scale. Those include aircraft certification, manufacturing and the launch of passenger operations. The Boeing acquisition would also expand Archer beyond air taxis and deeper into autonomous aviation and defense if the transaction closes as planned.
