Cathie Wood's latest buys follow a familiar ARK playbook: lean into volatility when you still believe in the long-term trend.
The trades touch a few different tech segments — AI chipmakers like Nvidia and Cerebras, cloud networking through Cloudflare, space exposure via Rocket Lab and SpaceX, and tokenization with Securitize.
It's not simply a broad tech rally bet, though. ARK has been trimming its positions in Palantir, Shopify and Snowflake at the same time. The pattern looks more like a rotation toward infrastructure-focused names rather than a blanket AI bet. Same overarching conviction, just narrower execution.
What Did Cathie Wood Buy Most Recently?
ARKK bought 66,263 shares of Cerus, while ARKG added another 20,612 shares. ARKG also purchased 4,717 shares of Schrödinger and 45,010 shares of Perceptive Capital Solutions.
Schrödinger is the clearest technology name in that group. Its computational platform uses physics-based modelling and machine learning in drug discovery, placing it at the intersection of biotechnology and AI.
ARKW and ARKF also purchased small positions in the 3iQ Solana Staking ETF. The purchases were modest, but they show that ARK continues to seek exposure to blockchain infrastructure alongside public technology companies.
The more substantial technology trades occurred earlier in the week.
Cerebras Is ARK’s Most Visible New AI Chip Bet
ARK bought heavily into Cerebras Systems on August 13. Trade summaries based on the firm’s disclosures show that ARKK purchased 83,366 shares, while ARKW added 23,575 shares.
Cerebras is attempting to solve AI computing problems differently from Nvidia. Instead of assembling clusters around conventional GPUs, the company builds wafer-scale processors designed to handle large AI workloads with fewer individual chips.
That does not make Cerebras a direct replacement for Nvidia across every use case. Nvidia has a much larger software ecosystem, an established developer base and strong relationships with cloud providers. Cerebras is a smaller company trying to prove that its architecture can win customers in selected training and inference workloads.
ARK’s purchases suggest that it sees room for more than one important AI chip supplier. The investment case is not simply that demand for AI computing is growing. Cerebras must also demonstrate that it can turn technical performance into recurring revenue while competing against a company with Nvidia’s scale.
The risks are equally clear. AI hardware is capital-intensive, customer relationships can be concentrated, and rapid product cycles require continuous spending. A promising architecture does not guarantee durable margins or market share.
Why Is ARK Buying Nvidia Again?
ARK revisited Nvidia during the recent tech pullback.
Trade data from August 10 shows purchases across ARKK, ARKW, ARKQ, ARKX and ARKF, adding up to about 122,000 shares. The buying came after weakness in AI and semiconductor names — exactly the kind of dip ARK has historically leaned into when its long-term view holds firm.
Nvidia remains the dominant player in AI data center hardware, and its edge goes beyond silicon. CUDA, networking, the developer ecosystem — customers are locked into the stack. That's not easily replicated.
ARK has bought and sold Nvidia multiple times over the years, trimming after big runs and reloading on pullbacks. The latest buys fit that pattern more than they signal a definitive bottom.
Still, it's worth noting: ARK may be adding Cerebras and newer AI names to the mix, but it hasn't walked away from the leader. The conviction is still there.
Cloudflare Adds a Different Kind of AI Exposure
ARKK purchased 31,974 Cloudflare shares on August 12. During the same session, it reduced positions in Palantir, Shopify and Snowflake.
Cloudflare does not manufacture AI chips. Its network sits between users, applications and online services, providing security, content delivery, developer tools and edge-computing capacity.
As AI applications expand, more inference workloads may need to run close to users rather than exclusively inside large centralized data centers. Cloudflare’s network gives it a possible role in delivering those applications, protecting their traffic and providing developers with the infrastructure needed to operate them.
This is a different investment from buying a model developer or chipmaker. Cloudflare’s opportunity depends on whether AI-related usage becomes meaningful revenue rather than simply adding traffic to its network.
The company also faces competition from major cloud providers and other content-delivery and security platforms. Investors must separate the size of the AI narrative from Cloudflare’s ability to monetize it.
Rocket Lab and SpaceX Keep Commercial Space in the Portfolio
ARK’s recent activity has not been limited to AI. On August 11, ARK bought Rocket Lab across several funds, with ARKK accounting for roughly 201,000 shares. ARKQ and ARKX also added to their positions.
Rocket Lab began as a launch company, but its business now reaches further into satellite components, spacecraft manufacturing and space systems. This gives ARK exposure to the infrastructure behind the space economy rather than relying only on launch frequency.
The firm also increased its SpaceX holdings in late July. Reports based on ARK’s trade disclosures estimated that it bought approximately $12.2 million of SpaceX shares on July 28, alongside purchases of Tesla and Nvidia.
Commercial space investments carry long development timelines and considerable execution risk. Launch delays, technical failures, government contract changes and high capital requirements can all affect results. Private or recently listed companies may also be difficult to value because their future businesses are still taking shape.
ARK appears willing to accept those risks in exchange for exposure to satellite connectivity, reusable launch systems and space-based infrastructure.
Securitize Connects Technology Stocks With Crypto
One of ARK’s most relevant purchases for digital-asset investors is Securitize. ARKF bought 192,702 SECZ shares on August 13, extending a position that ARK had already been building after the company’s public listing.
Securitize provides regulated infrastructure for issuing, managing and trading tokenized securities. The company completed its business combination with Cantor Equity Partners II in July and began trading on the New York Stock Exchange under the SECZ ticker.
According to Securitize, more than $4 billion of assets had been brought on-chain through its platform at the time of the listing.
The company offers public-market exposure to the real-world asset tokenization theme. Instead of buying a crypto token whose value depends on protocol incentives, investors are buying shares in a company that provides issuance, transfer-agent, brokerage and fund-administration services.
That structure does not remove risk. Securitize remains exposed to regulation, competition, client concentration and the pace at which financial institutions adopt tokenized assets. Its short history as a listed company also makes valuation more difficult.
ARK’s continued buying shows that it regards tokenization as part of financial infrastructure, not merely a temporary crypto narrative.
Why Is ARK Selling Palantir, Shopify and Snowflake?
During the same week, the firm reduced positions in Palantir, Shopify, Snowflake and several other growth companies. These sales could reflect valuation concerns, portfolio limits or the need to fund new purchases.
A sale does not necessarily mean ARK has rejected a company’s long-term prospects. Actively managed ETFs regularly trim holdings after price increases to prevent a single stock from becoming too large.
Palantir is a useful example. Its association with AI, defense and government software has attracted substantial investor attention. Reducing the position after a strong period could be a decision about weight and risk rather than a negative judgment on the underlying business.
The more useful signal is the direction of the capital. ARK has been moving some money from well-owned software companies into AI hardware, cloud infrastructure, commercial space and tokenized financial markets.
What the Recent Purchases Say About ARK’s Strategy
ARK’s current technology exposure covers several layers of the same economic shift.
Nvidia and Cerebras supply computing hardware. Cloudflare provides network and application infrastructure. Rocket Lab and SpaceX build physical systems for the space economy. Securitize develops financial infrastructure for assets moving on-chain. Schrödinger applies computing and AI to drug discovery.
These companies have little in common at the product level. What connects them is ARK’s belief that computing, automation and digital infrastructure will reshape established industries.
That approach creates opportunities, but it also produces concentrated exposure to high-growth companies. Many of these stocks are sensitive to interest rates, capital availability and changes in investor sentiment. Their valuations frequently rely on revenue or profits expected several years in the future.
If economic growth weakens or financing becomes more expensive, the market may apply lower valuation multiples even when the companies continue expanding.
What Matters Next
The next useful signal will be whether ARK continues buying these companies after the recent market volatility passes.
Further Cerebras purchases would indicate growing conviction in alternative AI hardware. Continued Nvidia buying would show that ARK still sees value in the established leader. Cloudflare’s position will depend on evidence that AI workloads are contributing to growth, while Securitize must demonstrate that tokenized assets can produce recurring revenue at scale.
Cathie Wood’s latest purchases do not offer a simple list of stocks to copy. They show where one high-profile innovation investor believes the next layer of technology infrastructure may be developing.
