Cathie Wood’s ARK Invest sent a strong signal through its semiconductor portfolio adjustments on Thursday, May 14, 2026. The investment firm divested holdings in three well-established chip manufacturers while simultaneously acquiring shares in one of the year’s most anticipated initial public offerings.
The largest divestment involved 41,540 Taiwan Semiconductor shares, generating approximately $16.6 million. This transaction occurred as the semiconductor giant’s stock surged 4.4% to reach a record closing price of $421.97. ARK has been systematically reducing its Taiwan Semiconductor stake across multiple trading sessions.

Additionally, ARK unloaded 11,510 shares of Advanced Micro Devices, worth approximately $5.1 million. This move extends a pattern of decreasing AMD holdings that has emerged throughout the previous week across ARK’s portfolio of exchange-traded funds.
Teradyne represented another semiconductor-related holding that ARK retreated from. The investment firm disposed of 22,576 shares with a value near $8.2 million. This follows previous Teradyne sell-offs, indicating a strategic withdrawal from this position.
Beyond the chip sector, ARK liquidated shares across three additional holdings. These transactions included 11,602 Twist Bioscience shares for $631,032, 35,073 Adaptive Biotechnologies shares for $460,508, and 13,525 CareDx shares for $278,750.
ARK Makes Aggressive Move Into Cerebras Following Explosive Market Debut
Regarding acquisitions, ARK’s purchasing activity focused exclusively on Cerebras Systems. The firm accumulated 105,616 shares distributed across two investment vehicles — the ARK Innovation ETF and the ARK Next Generation Internet ETF — representing a total investment of $4.85 million.
Cerebras operates as an artificial intelligence chip manufacturer recognized for producing wafer-scale processors engineered specifically for AI inference applications. The firm set its IPO price at $185 per share on May 13. Market demand allegedly exceeded available shares by more than 20-fold.
When Cerebras stock commenced public trading on May 14 under the ticker symbol CBRS, shares launched at $350. The stock concluded its inaugural trading session at $311, maintaining substantial gains above the initial offering price.
This first-day trading performance elevated Cerebras to a market capitalization approaching $49 billion. The enterprise has captured investor interest through its collaborations with OpenAI and a strategic alliance with Amazon Web Services.
Strategic Implications Behind ARK’s Portfolio Adjustments
The logic behind Thursday’s transactions is transparent. ARK liquidated holdings in firms experiencing robust recent price momentum, including Taiwan Semiconductor at its peak valuation, while channeling investment capital toward a nascent, high-velocity growth opportunity.
This methodology aligns with ARK’s established investment philosophy of exiting appreciated positions and reallocating funds into emerging companies positioned within rapidly evolving technology sectors.
Cerebras exemplifies this investment criteria. The AI chip space continues attracting substantial capital as data center infrastructure requirements expand. Cerebras occupies a strategic position within this ecosystem, having established tangible commercial partnerships.
These portfolio changes were revealed through ARK’s daily transparency reports, which the firm releases following each market session. As of May 14’s closing bell, Cerebras registered among the most successful IPO launches within the AI hardware sector to date.
