Cathie Wood’s Ark Invest stepped up its exposure to two high-profile growth companies on Wednesday, purchasing approximately $17.3 million of Circle Internet Group (NYSE: CRCL) shares and nearly $20 million of SpaceX (NASDAQ:SPCX) stock. The moves, detailed in the firm’s official daily trade disclosures, came as both companies released second-quarter results that mixed solid operational gains with market concerns.
Ark acquired 273,343 shares of Circle, the issuer of the USDC stablecoin, across its Ark Innovation ETF (ARKK), Next Generation Internet ETF (ARKW), and Blockchain & Fintech Innovation ETF (ARKF).
Circle’s stock closed essentially flat, up 0.05 percent at $63.28, valuing the new purchases at about $17.3 million.
The addition keeps Circle as a notable holding within Ark’s portfolios, currently ranking near the top tier in ARKK.
The buying coincided with Circle’s quarterly report.
The company posted total revenue and reserve income of $701 million, a 7 percent increase from the year-earlier period, while adjusted EBITDA rose 8 percent to $143 million.
USDC circulation ended the quarter at $73.3 billion, up 19 percent year-over-year, and on-chain transaction volume climbed 151 percent to $14.8 trillion.
These figures highlighted continued expansion in stablecoin usage even as broader market conditions remained uneven
.On the same day, Ark added 181,830 shares of SpaceX across ARKK, the Autonomous Technology & Robotics ETF (ARKQ), ARKW, and the Space & Defense Innovation ETF (ARKX).
The purchases were valued at roughly $19.7 million based on the day’s closing price. SpaceX shares, however, fell sharply, dropping 13.61 percent to $108.27—below the company’s IPO level of $135.SpaceX reported strong top-line growth, with revenue surging 92 percent year-over-year to $7.8 billion.
Investors focused instead on elevated capital spending of $18.4 billion in the quarter, largely directed toward expanding artificial-intelligence infrastructure.
Despite the sell-off, SpaceX leadership expressed confidence in reaching $1 trillion in annual revenue by 2030 or possibly earlier.
Ark’s strategy of concentrating on disruptive innovators while capping individual positions below 10 percent of any fund remains consistent.
By adding to both Circle and SpaceX after their earnings releases, the firm signaled belief that longer-term growth potential outweighs near-term volatility tied to spending levels and competitive pressures. These transactions reflect Ark’s ongoing emphasis on companies advancing blockchain finance and multi-domain technology platforms spanning connectivity, space, and AI.
