Cathie Wood’s ARK added Nvidia as AI stocks slid, according to a new market report

Cathie Wood’s ARK Investment Management added to its positions in several high-profile technology and innovation companies during a recent AI sell-off, according to a Yahoo Finance report published on Aug. 10, 2026.

The report states that ARK bought roughly $40 million of Nvidia, Tesla and SpaceX over the prior month, framing the purchases as a bet that parts of the AI complex may have become temporarily cheaper after the market’s decline. It also notes Wood’s long-standing enthusiasm for these “industry leaders,” though it does not provide additional, company-specific operational details in the headline-driven account.

For Nvidia, the most relevant immediate takeaway is not a new product announcement or guidance change, but the market timing. In periods when investor sentiment toward AI infrastructure weakens, fund managers who target disruptive technology often look to add exposure, particularly when they believe the underlying demand trends will reassert themselves.

For Tesla and SpaceX, the same report highlights ARK’s broader willingness to hold and acquire exposure to companies tied to transport and space ambitions, areas that frequently trade on long-horizon narratives. However, the report’s framing does not include disclosures about the exact ARK fund vehicles involved, the number of shares or dollar amounts by company, or whether the trades were concentrated in one or multiple trading days.

This is the kind of portfolio action that tends to attract scrutiny because ARK funds are designed around thematic investing, and their trades can be interpreted by observers as either contrarian positioning or a response to catalysts outside the companies themselves. In the case of a “sell-off,” the catalyst cited is the market’s broad movement in AI-related expectations, not any single disclosed development from Nvidia, Tesla or SpaceX in the report.

In addition, the report’s question, “Was She Right to Buy the Dip?,” underscores the uncertainty embedded in timing bets. Even when a fund has a clear thesis, the outcome depends on how quickly AI-related earnings expectations stabilize, and whether the market’s valuation reset broadens or reverses.

Nvidia, in particular, typically moves with broader investor sentiment about the pace of AI infrastructure buildouts. The Yahoo Finance report does not, however, spell out whether ARK’s buying corresponded to any specific Nvidia milestone, such as new customer wins, a product transition, or updated financial forecasts. Without those details in the published account, investors are left to infer the rationale largely from the fund’s established thematic posture and the overall “AI sell-off” context.
