Cathie Wood’s ARK funds sell AMD as they add $17.2 million to Cerebras, according to Yahoo Finance

Cathie Wood’s ARK investment funds reportedly reduced exposure to Advanced Micro Devices as they increased holdings in Cerebras, according to a Yahoo Finance report dated Aug. 26, 2026. The same report said ARK bought $17.2 million of Cerebras shares, while “dumping” AMD, a move that highlights how actively managed strategies can rotate quickly between established semiconductor suppliers and newer AI infrastructure bets.

AMD, a long-time supplier of processors and accelerators used in data centers, has been a central name in investors’ AI expectations for years, largely because of its push to compete in the market for AI compute. ARK’s reported move does not, by itself, indicate that AMD has lost product relevance, but it does show that even well-followed semiconductor names can be deprioritized by certain funds when portfolio managers rebalance around their own themes.

The Yahoo Finance report focused on the transaction decision rather than offering details about AMD-specific operating changes or new guidance that prompted the sell. In this instance, there is no information in the provided materials about the size of the AMD reduction, whether it was a full exit or partial trimming, or what cost basis or timing ARK used to execute the trade.

By contrast, the report is more specific about the Cerebras purchase, stating that ARK bought $17.2 million of Cerebras shares. Cerebras is commonly discussed in the context of AI chip infrastructure, and funds that emphasize thematic AI exposure often look for companies they believe can capture next-generation demand for specialized compute. Still, the provided report excerpt does not detail how ARK framed the Cerebras bet, such as whether the purchase was tied to a particular product milestone, customer win, or financial disclosure.

Market observers often watch ARK trades as a announcement of how a popular “disruptive innovation” approach is shifting, especially when money moves across the AI hardware stack. The reported rotation from AMD to Cerebras suggests ARK funds may be adjusting exposure toward a different slice of the AI computing ecosystem, where investors may perceive distinct growth timelines or competitive advantages.

Sector context matters, because AI chip investing spans both incumbent semiconductor platforms and newer architectures. Established suppliers like AMD tend to be valued for scale, broad deployment, and the ability to sell across multiple workloads, while younger AI chip companies are often evaluated on whether they can move from prototype performance to production deployments. ARK’s reported transactions fit that broader pattern of thematic funds moving between maturity profiles as their internal models and risk assumptions evolve.

A key caveat is what the report does not provide in the materials here. There is no disclosed rationale from ARK, no disclosed breakdown by which specific ARK fund or funds conducted the AMD sale, and no disclosed explanation of whether the Cerebras buy reflected a long-term increase in conviction or a shorter-term rebalancing move. Without those details, it is not possible to link the trades to specific AMD developments or to confirm the precise rationale behind ARK’s portfolio change.

Looking ahead, investors may want to watch for follow-on filings or disclosures that can confirm the size and timing of the AMD reduction and the exact ARK funds involved, as well as any subsequent updates from both companies about AI platform adoption. For AMD, the question is whether broader market demand for its data center and AI offerings continues to match expectations. For Cerebras, the focus would be on whether the company’s commercialization progress supports the kind of thematic accumulation ARK is reported to have made. Both paths will likely remain sensitive to quickly changing views on AI compute demand and competitive positioning.
