ARK Invest adds $18.18 million to CoreWeave position despite OpenAI slowdown fears

Cathie Wood's ARK Invest executed a substantial purchase of 162,306 shares of CoreWeave on April 28, valuing the transaction at approximately $18.18 million. The acquisition occurred across the ARKK and ARKW ETFs and was made immediately following a 5.83% decline in CoreWeave's share price. The drop was triggered by reports that OpenAI had missed internal revenue and user growth targets, a development that caused most investors to pause. For Wood, however, the selloff presented a clear opportunity to accumulate shares of the AI infrastructure firm.

This single transaction represents a significant step in a broader accumulation strategy, as ARK Invest has now invested at least $80 million in CoreWeave shares year to date in 2026. The pattern suggests a deliberate build rather than a one-off trade, with Wood consistently adding to her position whenever the stock pulls back. Wood's conviction appears rooted in the belief that the recent market reaction is disconnected from CoreWeave's underlying business strength, despite the company's high debt-to-equity ratio of 4.85 and its reliance on OpenAI under a potential $11.9 billion revenue deal.

CoreWeave operates as a GPU-optimised cloud infrastructure company specifically designed for AI workloads. While OpenAI remains a major customer and investor, the company has diversified its client base to include nine of the top 10 global AI platforms, such as Google, Microsoft, Meta, and Anthropic. This breadth of relationships is a key factor supporting Wood's willingness to maintain exposure, even as the stock remains volatile. The company's revenue has more than doubled in each of its first four quarters since its IPO, a growth trajectory that continues to underpin the investment thesis.

The purchase on April 28 was not an isolated event but part of a wider rotation by ARK Invest on that day. Wood also acquired 40,656 shares of Alphabet for approximately $14.17 million ahead of the tech giant's Q1 2026 earnings report. Additionally, the fund added 98,393 shares of Kratos Defense and Security Solutions for about $6.2 million. On the sell side, ARK reduced its position in Bullish, a crypto exchange and media company. The combined activity indicates an aggressive shift into AI infrastructure and adjacent themes while trimming digital asset exposure.

Despite the bullish signal from ARK, the investment landscape for CoreWeave remains complex. The company has taken on significant leverage to fund its infrastructure expansion, and a slowdown at OpenAI could create pressure on its growth trajectory given the balance sheet constraints. Analyst consensus currently rates CoreWeave as a Moderate Buy with an average price target of $114.20, implying roughly 8% upside from the levels at the time of the report. Wood's purchases do not eliminate these inherent risks but signal a strong belief that the long-term growth potential justifies accepting them.
