Ark Invest Adds Block and Circle Shares
The purchases give Ark Invest additional exposure to two publicly traded companies with significant roles in the digital-asset and financial technology sectors.
On Aug. 31, the investment firm bought 456,059 shares of Block for $37.4 million. Block operates financial technology businesses that include payments and other financial services — best known for its Square point-of-sale platform and the Cash App consumer finance service — while its ecosystem also has exposure to cryptocurrency through its products and services, including bitcoin holdings and bitcoin-related features for its customers.
The same day, Ark Invest acquired 35,192 shares of Circle worth $3.4 million. Circle is the issuer of USDC, a U.S. dollar-backed stablecoin used across digital-asset markets and blockchain-based financial applications. USDC is one of the largest stablecoins by circulating supply, and Circle listed its shares on the New York Stock Exchange in June 2025, giving public-market investors direct exposure to a stablecoin issuer's business.
The reported transactions show Ark Invest allocating capital to both companies in the same trading session, although the information shared by Cointelegraph does not specify the individual purchase prices or the investment strategy behind the transactions.
Cathie Wood's Investment Activity
Ark Invest, led by Cathie Wood, is known for investing in companies it views as positioned around long-term technological trends. Its publicly disclosed trading activity is closely followed by investors because the firm's portfolio changes can provide insight into its exposure to emerging financial technologies. Ark publishes daily trade disclosures for its exchange-traded funds, which is how transactions such as the Aug. 31 purchases become publicly visible.
The Aug. 31 transactions involve two different areas of the financial technology market. Block has developed a broad payments and financial-services business, while Circle's operations are closely tied to the expanding use of digital currencies and blockchain-based payments — a segment that has drawn increased attention as U.S. lawmakers moved in 2025 to advance stablecoin legislation, including the GENIUS Act signed into law in July 2025, which established a federal regulatory framework for payment stablecoins.
The size of the Block purchase was substantially larger than the Circle transaction. Ark Invest acquired $37.4 million worth of Block shares compared with $3.4 million of Circle shares, based on the figures reported.
Block and Circle Purchases in Focus
The purchases come as publicly traded digital-asset-related companies continue to attract attention from institutional investors. Ark Invest's latest reported transactions provide a specific snapshot of how the firm adjusted its holdings on Aug. 31.
The available information does not state whether the purchases were made across one or more Ark Invest funds, nor does it identify the prices at which the individual shares were acquired. It also does not indicate whether further purchases or sales followed the transactions.
Investors will therefore be watching subsequent disclosures for any additional changes involving Block and Circle, particularly whether the Aug. 31 purchases form part of a broader adjustment to Ark Invest's holdings.
