TLDR
- ARK Investment Management divested more than 100K Taiwan Semiconductor Manufacturing shares valued at $40.6M
- The firm acquired approximately 255K shares in AI chip manufacturer Cerebras Systems
- ARK purchased over 162K shares of AI-powered healthcare company Tempus AI

Cathie Wood’s ARK Investment Management executed several notable portfolio adjustments last week, reducing semiconductor exposure while expanding positions in artificial intelligence infrastructure and healthcare technology.
The most significant divestment involved Taiwan Semiconductor Manufacturing Company. Between May 14 and 15, ARK portfolios liquidated 100,549 shares of the foundry giant, representing approximately $40.6 million in value. TSMC stock has appreciated roughly 35% since the beginning of the year. The semiconductor manufacturer recently upgraded its projection for the global chip market to reach $1.5 trillion by 2030, revising upward from a previous $1 trillion estimate, with artificial intelligence and high-performance computing anticipated to drive 55% of that expansion.
Taiwan Semiconductor Manufacturing Company Limited, TSM
The chipmaker delivered impressive first-quarter 2026 financial results, recording revenue growth of 35.1% and net income expansion of 58.3%. TSMC’s chief executive characterized artificial intelligence demand as “extremely robust.” Nevertheless, the semiconductor manufacturer does not appear among ARK’s ten largest portfolio positions.
ARK Investment Management also liquidated approximately 62K shares of Advanced Micro Devices representing $10.9M, alongside more than 57K Teradyne shares valued at $20.7M. These transactions occurred as the iShares Semiconductor ETF experienced a roughly 4% decline on May 15.
ARK Expands AI and Healthcare Technology Positions
Regarding acquisitions, ARK purchased approximately 255K Cerebras Systems shares, marking one of its most substantial single-week purchases. Cerebras specializes in AI compute infrastructure and has generated increasing attention from the investment community.
The firm also acquired more than 162K Tempus AI shares, a healthcare diagnostics company leveraging artificial intelligence technology. ARKK added 132K Intellia Therapeutics shares and 52K Natera shares, maintaining its commitment to precision medicine investments.
Within financial technology, ARK purchased nearly 42K Circle Internet shares distributed across three separate funds, enhancing its exposure to digital payment systems and cryptocurrency-related financial infrastructure.
ARK also acquired over 61K Kodiak AI shares and 183K Kratos Defense shares, extending a consistent pattern of expanding defense technology positions.
ARKK Performance and Wood’s Market Perspective
The Ark Innovation ETF, ARK’s flagship investment vehicle, has retreated 3.81% in 2026 thus far, underperforming the S&P 500 which has advanced more than 8%. Examining a five-year timeframe, ARKK has generated an annualized return of -6.25%, contrasting with the S&P 500’s 13.80% performance, based on Morningstar data.
Despite this performance gap, Wood maintains her optimistic long-term perspective. She has characterized the present environment as a “great acceleration” propelled by artificial intelligence and emerging technologies, rejecting comparisons to speculative market bubbles.
“AI training costs are dropping 75% per year,” Wood stated during a recent Bloomberg podcast appearance, noting that inference costs are decreasing at an even more rapid pace.
Investor appetite for ARK investment products appears resilient. The Ark Innovation ETF recorded approximately $1.48 billion in net capital inflows during the five-day period concluding May 14, according to ETF analytics provider VettaFi.
As of May 15, ARK’s largest portfolio allocations include Tesla at 11.16%, AMD at 5.57%, and Circle Internet at 5.23%.
