On Friday, September 11, 2026, Cathie Wood’s ARK Invest executed a series of strategic portfolio adjustments, divesting from multiple holdings while increasing exposure to businesses positioned in artificial intelligence and aerospace sectors.
The most significant divestment involved 46,015 Twist Bioscience shares through the ARKK ETF, representing approximately $5.8 million in value. This exit continues a multi-week trend of reducing exposure to this holding.
Additional portfolio reductions included 60,556 shares of 10X Genomics valued at roughly $4 million, alongside 121,217 Bullish shares totaling about $4.1 million. More modest exits encompassed Tempus AI, GeneDx Holdings, and Alphabet positions.
Conversely, ARK increased its stake in Intellia Therapeutics by acquiring close to 115,000 shares, representing approximately $1.4 million. This purchase extends a consistent buying pattern in the gene-editing enterprise throughout recent trading sessions.
Meta Becomes Major ARK Holdings
On September 9, two separate ARK funds collectively acquired $27.9 million in Meta Platforms shares. The social media giant’s stock currently trades approximately 18% beneath its peak valuation.
According to ARK’s analysis team, Meta’s impressive base of 3.6 billion daily active users across its application ecosystem represents a significant competitive moat. The technology company is deploying artificial intelligence to enhance advertising precision and content recommendation systems throughout its platform network.
The company’s second-quarter financial results showed revenue expanding 28% compared to the previous year. Mark Zuckerberg, Meta’s CEO, emphasized that the company’s advertising division is experiencing faster dollar-based growth than any competing platform’s reported advertising operations.
Meta has allocated between $165 billion and $169 billion for capital investments throughout 2026. Wood’s investment thesis suggests these expenditures will ultimately drive enhanced free cash flow generation. The equity currently commands a forward price-to-earnings ratio of 21.
Rocket Lab Draws Substantial ARK Investment
Between August 31 and September 8, three distinct ARK ETFs accumulated approximately $45 million in Rocket Lab equity. The aerospace company’s shares have retreated nearly 60% from the $151 all-time peak achieved earlier in 2026.
Rocket Lab’s second-quarter performance demonstrated 62% year-over-year revenue expansion, complemented by a company-record backlog reaching $2.36 billion. Since the end of the first quarter on March 31, the organization has secured $437 million in fresh contract commitments.
Peter Beck, serving as CEO, characterized the current demand environment for launch capabilities as “extreme.” Company leadership highlighted that available launch windows extending past 2029 are now “extremely limited,” potentially creating pricing advantages as market demand intensifies.
The company is also in the process of acquiring Iridium, which maintains a 66-satellite constellation serving more than 2.5 million users. Wood’s investment strategy appears focused on establishing Rocket Lab as a foundational space infrastructure investment for the long term.
ARK’s primary ARKK ETF has generated approximately 9% returns during 2026, underperforming broader market benchmarks. However, four additional ARK-managed funds have delivered superior returns relative to the S&P 500 across the trailing three-year period.
The most recent ARK portfolio adjustments reveal a concentrated emphasis on AI-enabled platforms and aerospace infrastructure as the final quarter of 2026 approaches.
