Cathie Wood's Ark Invest acquired approximately $17.3 million in Circle Internet Group shares and nearly $19.7 million in SpaceX stock on August 5, shortly after both companies released their second-quarter earnings reports. The purchases were distributed across several Ark exchange-traded funds and followed volatile trading sessions for both stocks. Ark Invest, known for focusing on companies it identifies as operating in disruptive innovation sectors, has consistently built positions in both digital assets infrastructure and space technology through its ETF lineup.

Circle Share Purchase

Ark Invest bought 273,343 Circle shares across three ETFs: ARKK, ARKW, and ARKF. ARKK received the largest allocation at 194,333 shares, while ARKW added 55,135 shares and ARKF purchased 23,875 shares.

Circle closed at $63.28, gaining 0.05% for the session, valuing the total purchase at roughly $17.3 million. The stock now ranks as the ninth-largest holding in ARKK, representing a 3.68% portfolio weight.

The acquisition followed Circle's second-quarter earnings report. Revenue and reserve income reached $701 million, up 7% year over year but falling short of the Wall Street estimate of approximately $713 million. Adjusted EBITDA rose 8% to $143 million, and net income from continuing operations came in at $48 million.

On the digital assets front, USDC circulation grew 19% to $73.3 billion, while onchain transaction volume surged 151% to $14.8 trillion. USDC remains the second-largest stablecoin by market capitalization, behind Tether's USDT. Circle reiterated its plan to launch the Arc Layer-1 blockchain mainnet on September 16, with BlackRock, DTCC, Visa, and Mastercard serving as founding validators. The mainnet launch positions Circle to compete in the growing tokenization and real-world asset settlement space, where traditional financial institutions have been expanding their blockchain-based operations.

Ark Invest has steadily increased its Circle position since the company received trust approvals in July. According to the firm's trade disclosures, additional Circle share purchases were made on July 31, May 12, and March 24.

SpaceX Share Purchase

Ark Invest also acquired 181,830 SpaceX shares across four ETFs: ARKK, ARKQ, ARKW, and ARKX. ARKK again received the largest portion at 104,008 shares.

SpaceX closed at $108.27 after a 13.61% decline, leaving the stock below its June IPO price of $135. At Wednesday's closing price, the Ark Invest purchase was valued at approximately $19.7 million. The purchase came as the stock traded down, a pattern consistent with Ark Invest's history of adding to positions during market pullbacks.

Despite the share price drop, SpaceX reported strong quarterly results. Revenue reached $7.8 billion, up 92% year over year and surpassing the $6.8 billion analyst estimate. The company's net loss narrowed to $541 million, while adjusted EBITDA soared 191% to $3.5 billion.

Investors closely examined quarterly capital expenditures totaling $18.4 billion, with approximately $16 billion directed toward AI computing infrastructure. The capital deployment reflects SpaceX's broader push into AI-driven services alongside its core launch and connectivity businesses.

The first insider lock-up tranche also expires on August 6, permitting some restricted shares to enter the public market.

SpaceX disclosed that Starlink subscribers doubled to 12 million. The company maintained its target of reaching a $100 billion annualized revenue run rate by December.
