Key Highlights Ark Invest accumulated approximately $37M in SpaceX stock following the company’s earnings-related decline, representing the week’s top purchase The stablecoin issuer Circle In
During the opening week of August, Cathie Wood’s Ark Invest executed substantial portfolio adjustments, significantly increasing positions in aerospace, artificial intelligence infrastructure, and digital assets while simultaneously reducing stakes in gaming, enterprise software, and medical technology sectors.
The aerospace manufacturer SpaceX emerged as Ark’s most substantial acquisition for the period. The investment management firm accumulated 316,963 shares distributed across four distinct funds, representing a combined investment of approximately $36.9M. Ark initiated purchases on August 5 when shares declined 13.6% immediately after the company released its inaugural earnings report as a publicly traded entity. SpaceX reported revenue reaching $7.8B, marking a 92% increase compared to the previous year, though market participants initially responded unfavorably to the company’s substantial AI infrastructure capital expenditures. Ark resumed purchasing on August 7 as shares recovered with a 15.8% gain.

Circle Internet Group secured the position as the week’s most significant cryptocurrency-related acquisition. Ark accumulated 610,177 shares with an approximate value of $39M. These purchases occurred following Circle’s second-quarter revenue figures that fell short of analyst projections. The circulation of Circle’s USDC stablecoin expanded 19% year-over-year to reach $73.3B, while onchain transaction volumes surged 151% to $14.8T.
Coinbase represented another noteworthy expansion. Ark acquired 114,444 shares valued at approximately $17M. Block also received attention, with 267,676 shares purchased totaling about $21M.
Ark secured 169,616 shares of CoreWeave for $13.2M, expanding its position in GPU-based cloud computing infrastructure. The investment firm additionally acquired 65,677 shares of Cerebras Systems for $13.1M, targeting a specialist in AI-focused computing hardware.
Nvidia received allocations across five separate funds, with 80,415 shares acquired for approximately $17.6M. Nvidia’s data center networking division reported revenue growth approaching 200% year-over-year in the most recent quarter. The four dominant hyperscale cloud providers are projected to allocate up to $725 billion in capital expenditures this year, representing a 77% annual increase, with Nvidia positioned to secure a substantial share of these investments.
Cloudflare experienced both selling and buying activity within the same timeframe. Ark initially divested shares early in the week before reversing direction and purchasing 114,134 shares worth $35.4M following Cloudflare’s announcement of 35.9% revenue expansion and improved full-year guidance. Amazon also joined the purchase list, with 73,835 shares acquired for roughly $21M.
Roblox represented by far the most substantial divestment. Ark liquidated 2.64M shares valued at roughly $96M, including a single-day transaction of 1.6M shares from one fund on August 7. The stock appreciated 4.9% during that trading session.
Shopify experienced $35M in share sales spanning three funds. Palantir faced a $21M position reduction. More modest decreases affected AMD, Snowflake, CrowdStrike, Natera, and Roku.
Industrial sector holdings including Caterpillar, Garmin, Deere, and Komatsu also underwent position trimming.
