Cathie Wood’s investment firm ARK Invest executed significant portfolio adjustments on Tuesday, June 23, accumulating positions in prominent technology companies while trimming its Roku exposure.
The firm divested 327,053 Roku shares across ARKK, ARKW, and ARKF portfolios, representing approximately $44.2 million in value. This continues ARK’s ongoing pattern of reducing Roku exposure throughout recent trading sessions.
Meanwhile, ARK deployed roughly $49.3 million toward building multiple strategic positions.
Major Positions: Palantir and Amazon Take Center Stage
ARK accumulated 81,254 shares of Palantir valued at $9.48 million distributed across ARKK, ARKW, and ARKF funds. This move reverses previous selling activity in the data analytics company. Palantir currently ranks as the 16th-largest position within ARK Innovation ETF, comprising 2.58% of holdings.
Palantir Technologies Inc., PLTR
Simultaneously, ARK secured 41,141 Amazon shares totaling $9.63 million across identical funds. The e-commerce and cloud computing giant represents the 18th-largest position in ARKK, accounting for 2.36% of assets.
The investment firm added 21,226 Tesla shares valued at $8.1 million. Tesla maintains its status as the leading holding in ARKF, commanding 9.73% of that portfolio.
ARK accumulated 23,603 Alphabet shares worth $8.17 million. The search giant constitutes 1.92% of ARK Innovation ETF holdings.
Doubling Down on AI Infrastructure
ARK secured 76,195 CoreWeave shares for $8.06 million. CoreWeave ranks as the 17th-largest holding in ARKK, representing 2.57% of the fund.
Additionally, ARK purchased 25,795 Cerebras Systems shares totaling $5.85 million. The artificial intelligence chip manufacturer recently completed its public debut on May 14. This acquisition strategically preceded Cerebras’s first-quarter earnings report, which showed revenue exceeding expectations following Tuesday’s market close.
Cerebras comprises just 1.22% of ARK Innovation ETF currently, indicating the firm may be establishing a larger position over time.
On the previous trading day, ARK deployed $32.4 million into SpaceX across four ETF portfolios, capitalizing on a 16% stock decline. The firm had already acquired 3.3 million SpaceX shares during the company’s public market debut.
To finance that SpaceX acquisition, ARK liquidated hundreds of millions in holdings during the weeks preceding the initial public offering.
Tuesday’s trading activity demonstrates ARK’s strategic reallocation from Roku toward artificial intelligence infrastructure providers and Magnificent 7 technology stocks.
