Cathie Wood's Ark Invest, known for its thesis-driven bets on disruptive innovation, executed a series of significant portfolio moves during the first week of August, increasing its exposure to space exploration, AI infrastructure, and cryptocurrency-related equities while reducing positions in gaming, software, and industrial names.

SpaceX Leads the Week's Purchases

SpaceX was Ark's largest acquisition of the week. The firm purchased 316,963 shares across four funds for a combined value of approximately $36.9 million. Ark initiated the purchases on August 5, when the stock declined 13.6% following the company's first earnings report as a publicly traded entity. SpaceX reported revenue of $7.8 billion, representing a 92% year-over-year increase, though investors initially reacted negatively to elevated AI infrastructure spending. Ark added to its position again on August 7 as the stock rebounded 15.8%.

SpaceX trades under the ticker SPCX (Space Exploration Technologies Corp.).

Circle Internet Group Tops Crypto Additions

Circle Internet Group was the largest crypto-sector purchase. Ark acquired 610,177 shares valued at approximately $39 million. The purchases followed Circle's second-quarter revenue, which fell short of analyst expectations. Despite the miss, Circle's USDC stablecoin — the second-largest stablecoin by market capitalization — saw circulation grow 19% year over year to $73.3 billion, and onchain transaction volume surged 151% to $14.8 trillion.

Ark also expanded other crypto holdings. Coinbase saw an addition of 114,444 shares worth roughly $17 million, while Block was added with 267,676 shares purchased for approximately $21 million.

AI Infrastructure Builds Continue

Ark deepened its commitment to AI infrastructure with several purchases. The firm bought 169,616 shares of CoreWeave for $13.2 million, adding to its position in GPU-powered cloud infrastructure. Cerebras Systems, a company focused on AI computing hardware, saw an addition of 65,677 shares for $13.1 million.

Nvidia was added across five funds, with 80,415 shares purchased for approximately $17.6 million. Nvidia's data center networking revenue rose nearly 200% year over year in the most recent quarter. The four largest hyperscalers plan to spend up to $725 billion this year, a 77% year-over-year increase, and Nvidia is positioned to capture a substantial share of that spending.

Cloudflare experienced both buying and selling within the same week. Ark sold shares earlier in the week before reversing course and purchasing 114,134 shares valued at $35.4 million after Cloudflare reported 35.9% revenue growth and raised its full-year guidance. Amazon was also added, with 73,835 shares purchased for approximately $21 million.

Major Sales Led by Roblox

Roblox represented the week's largest divestment. Ark sold 2.64 million shares worth approximately $96 million, including 1.6 million shares from a single fund on August 7. The stock rose 4.9% on that day.

Shopify saw approximately $35 million in shares sold across three funds. Palantir was reduced by $21 million. Smaller reductions included AMD, Snowflake, CrowdStrike, Natera, and Roku. Industrial sector names — Caterpillar, Garmin, Deere, and Komatsu — were also trimmed. The industrial reductions continue a broader pattern of Ark moving capital away from legacy-economy sectors toward its core innovation themes.
