Cathie Wood’s ARK Invest buys $49 million basket including Palantir and Cerebras

Cathie Wood’s ARK Invest purchased a basket of high-profile technology and artificial-intelligence related stocks totaling about $49 million, according to a report published Tuesday by Yahoo Finance. The trades, attributed to Wood’s funds, included positions in Palantir and Cerebras, among other well-known companies.

The Yahoo Finance post said the purchases covered Amazon, Tesla, Alphabet, Palantir, CoreWeave and Cerebras. Palantir is a software company best known for data and operations platforms used in defense, government, and commercial settings. Cerebras is associated with hardware designed to run AI workloads at scale, reflecting investor interest in the compute stack rather than only software.

Palantir shares trade on the Nasdaq under the ticker PLTR. The inclusion of Palantir in ARK’s buying list reinforces a theme that has been visible in recent years across active exchange-traded funds focused on innovation, where portfolio managers try to balance established platform companies with faster-growing infrastructure and AI-exposed names.

ARK’s activity is also notable in the broader context of what the purchases suggest about market positioning. The same reported basket paired mega-cap tech exposure, such as Alphabet and Amazon, with more concentrated bets tied to AI infrastructure and deployment, represented here by CoreWeave and Cerebras. Tesla’s presence in the mix highlights that ARK’s approach continues to span both AI-adjacent computing and other technology-driven sectors.

Beyond the listed names, the Yahoo Finance report did not provide additional detail in the material available here, such as the specific ARK fund(s) involved, the number of shares bought, the exact trade dates and prices, or whether the purchases were part of a rebalancing effort or new conviction bets.

Company-specific implications for Palantir are limited by what is disclosed publicly in the post. While the reported buy indicates ARK Invest took exposure to PLTR as part of its strategy for that day, the post did not quantify how much of Palantir’s outstanding shares were affected, nor did it describe whether the new position would be expected to grow or remain stable over time.

For Cerebras, the reported inclusion points to continued investor attention on AI hardware, an area where outcomes can hinge on product execution and customer adoption. Still, the Yahoo Finance excerpt does not indicate any company milestone, contract, or guidance that would connect the purchase to a specific near-term catalyst.

What to watch next is whether ARK Invest files additional transaction details, such as through regular fund disclosures, and whether Palantir and Cerebras respond through corporate updates. For market participants, the more informative follow-up will be changes in position sizing across ARK’s funds and how those moves line up with upcoming earnings and product announcements.
