ARK Invest Buys $15.5 Million in NVIDIA Shares Amid Market Jitters

Cathie Wood's ARK Invest purchased 78,965 shares of NVIDIA (NVDA) for its flagship ARK Innovation ETF (ARKK) on July 28, 2026, a transaction valued at approximately $15.5 million. The investment follows a significant one-day sell-off in the chipmaker's stock, demonstrating ARK's strategy of buying into market dislocations.

Details of the Trade

The purchase was executed a day after NVIDIA's stock experienced a 5% decline. At the time of the transaction, NVIDIA shares closed at $197.01, which was approximately 16.7% below the stock's 52-week high of $236.54, according to the source material.

This move was part of a broader portfolio adjustment for ARK. On the same day, the firm also bought shares of Tesla (TSLA) and Intuitive Machines (LUNR) while selling its positions in Iridium (IRDM), Teledyne (TDY), CRISPR Therapeutics (CRSP), and Robinhood (HOOD). This activity suggests a strategic rotation into companies ARK views as central to AI infrastructure.

Market Context and Rationale

NVIDIA's recent stock decline was reportedly linked to investor unease following announcements of over $750 billion in AI-related deals, including partnerships with SK Group and OpenAI. The concern was not about a lack of demand for NVIDIA's products but rather about the potential balance sheet risks faced by its major customers committing to massive capital expenditures.

ARK Invest's purchase indicates it views these market fears as a short-term overreaction and a long-term buying opportunity. The firm is effectively making a conviction call on the durability of AI infrastructure spending, despite near-term financing questions.

Outlook for NVIDIA

The investment highlights a divergence between short-term market sentiment and some long-term growth theses. Key factors supporting a bullish outlook include the full production of NVIDIA's next-generation Vera Rubin AI chips and a $1.5 billion deal with Amkor to expand U.S.-based advanced packaging capacity, mitigating geopolitical supply chain risks.

However, potential headwinds remain, including ongoing U.S. export controls on technology sold to China and the risk of margin compression if customers face financing stress. The next major catalyst for the stock will be its earnings report scheduled for August 26, where Wall Street consensus projects revenues of approximately $91.8 billion.
