Ark Invest, the investment firm led by Cathie Wood, acquired approximately $37.4 million worth of shares in Block Inc. and roughly $3.36 million in Circle Internet Group stock during Monday’s trading session. The purchases continued the firm’s pattern of adding to positions in crypto-related companies during periods of share price movement.

Details of the Block Purchase

According to Ark Invest’s daily trading disclosures, the firm bought 456,059 shares of Block, the fintech company headed by Jack Dorsey. Based on the stock’s closing price of $82.02, the transaction totaled about $37.4 million. The shares were allocated across three actively managed exchange-traded funds: the ARK Innovation ETF, the ARK Next Generation Internet ETF, and the ARK Blockchain & Fintech Innovation ETF.

Block shares finished the day 1.85% lower. The latest buy follows earlier additions to the position this year. In June, Ark acquired 236,759 Block shares valued at roughly $17.2 million. In July, the firm purchased another 19,029 shares worth approximately $1.52 million.

Block reported second-quarter results showing gross profit of $3.17 billion, a 25% increase from the prior year. Square contributed $1.16 billion and Cash App $1.97 billion. Adjusted diluted earnings per share reached $1.02. Following the results, the company raised its full-year 2026 gross profit forecast to $12.51 billion and projected adjusted operating income of $3.47 billion.

The company also expanded its Bitcoin holdings by 85 BTC in June, bringing its treasury total to 9,117 BTC.

Circle Position Expanded

Ark simultaneously increased its stake in Circle Internet Group, the issuer of the USDC stablecoin, by purchasing 35,192 shares. At the Monday closing price of $95.55, the cost was about $3.36 million. Circle shares rose 9.65% on the day after a 7.5% decline in the previous session.

This marked another step in Ark’s accumulation of Circle stock during 2026. In July the firm bought 220,012 shares for approximately $13.9 million when the price traded below $64. Later that month it added 109,129 shares valued at about $6.83 million after Circle received a limited-purpose trust charter from the New York Department of Financial Services.

Circle reported second-quarter revenue of $701 million. USDC circulation stood at $73.3 billion at the end of the period. Bernstein recently maintained an Outperform rating on the shares and set a $140 price target, citing growth in stablecoin payments and related blockchain applications.

Ongoing Portfolio Adjustments

Ark’s strategy involves adjusting holdings to maintain target portfolio weights, with individual positions generally limited to no more than 10% of a fund. The firm has used declines in crypto-linked equities earlier this year to build exposure across several companies, including Block and Circle.

The combined Monday transactions brought Ark’s new investment in the two stocks to nearly $41 million, extending its focus on companies operating at the intersection of financial technology and digital assets.
