Cathie Wood’s ARK Invest bought about $40.2 million in Tesla, SpaceX and Nvidia shares on July 28 as a global technology sell-off hit AI and semiconductor stocks.
ARK Invest spread its Tesla purchases across four exchange-traded funds, according to the firm’s daily trade disclosures.
The ARK Innovation ETF (ARKK) bought 26,920 Tesla shares, the largest portion of the purchase. ARK Autonomous Technology & Robotics ETF (ARKQ) acquired 5,785 shares, while ARK Next Generation Internet ETF (ARKW) and ARK Space & Defense Innovation ETF (ARKX) added 5,119 and 2,457 shares, respectively.
The 40,281 Tesla shares were worth about $12.38 million based on the stock’s July 28 closing price of $307.44.
ARK also purchased 105,108 SpaceX shares across the same four funds. ARKK acquired 70,773 shares, followed by 15,213 for ARKQ, 9,426 for ARKW and 9,696 for ARKX.
The SpaceX investment was valued at about $12.24 million using the company’s $116.41 closing price. ARK had already purchased approximately $14 million in SpaceX shares earlier in the week, extending its exposure to Elon Musk’s aerospace company.
Nvidia was added to all five of ARK Invest’s active ETFs included in the July 28 disclosure.
ARKK bought 42,072 Nvidia shares, while ARKQ and ARKW purchased 13,639 and 11,984 shares. The ARK Fintech Innovation ETF (ARKF) added 5,471 shares, and ARKX acquired another 5,799.
The combined purchase of 78,965 shares was worth about $15.56 million based on Nvidia’s closing price of $197.01.
ARK’s buying followed a sharp decline in Nvidia shares on Monday as investors reassessed the cost and financing of AI infrastructure. The chipmaker also lost its position as the world’s most valuable publicly traded company to Apple during the market rotation.
Other U.S. semiconductor and data-storage stocks remained under pressure on Tuesday. Intel, AMD, SanDisk, Western Digital and Seagate Technology each fell more than 4% as concerns over data-center spending spread across the sector.
Asian equities recorded some of the steepest losses during the global retreat. South Korea’s Kospi dropped 10.8%, triggering a temporary circuit breaker after losses crossed 8%.
Samsung Electronics and SK Hynix fell by double digits as investors reacted to concerns over China’s progress in chipmaking equipment and the sustainability of AI investment. Japan’s Nikkei 225 also finished nearly 4% lower.
The sell-off followed a long rally in AI-linked companies and renewed debate over whether revenue from AI services can justify the amount being invested in chips, power supplies and data centers. ARK’s purchases indicate the investment manager used the decline to expand positions in companies tied to autonomous vehicles, space technology and computing infrastructure.
For U.S. investors, ARK’s trades offer exposure to those sectors through its actively managed ETFs. However, the purchases also increase sensitivity to further declines in high-valuation technology stocks if AI spending slows or financing costs remain elevated.
ARK also increased its indirect Solana exposure through the 3iQ Solana Staking ETF. ARKW bought 2,997 shares, while ARKF purchased 2,255 shares.
The combined 5,252-share purchase was valued at about $32,667 based on the fund’s $6.22 closing price. It followed ARK’s purchase of BitMine Immersion Technologies shares and the same Solana fund on July 24, when the firm invested roughly $251,500 across three ETFs.
ARK Invest’s director of digital assets research, Lorenzo Valente, separately warned on July 28 that the crypto industry was entering its deepest consolidation phase. He claimed Hyperliquid and Pump.fun generated 67% of application revenue, with Ethena lifting the top-three share to almost 80%.
Valente expects more acquisitions, bankruptcies and shutdowns as capital moves toward fewer businesses. However, his post did not disclose the dataset, category definitions, or measurement period used to calculate those figures.
