Cathie Wood’s Ark Invest just bought 262,463 shares of Block Inc., the payments company led by Jack Dorsey, on August 11, 2025.
The purchase was made after Block’s shares dropped 15% from their weekly high of $85. Ark Invest took advantage of this dip to increase its stake in the company.
According to the data, this purchase was spread across three of Ark’s funds: the Ark Fintech Innovation ETF (ARKF), the Ark Next Generation Internet ETF (ARKW), and another ARKF tranche. The total value of these shares is about $19.2 million. With this new buy, Ark Invest now holds Block shares worth $169 million, which makes up 1.62% of its total portfolio.
Block Inc. recently announced strong second-quarter earnings. The company reported a profit of $1.5 billion, up 16% compared to last year. Block’s stock also joined the S&P 500 index last month. This addition is expected to boost liquidity and attract more investors.
Cathie Wood, who leads Ark Invest, has been increasing her exposure to crypto-related firms. Earlier in August, she bought shares of Coinbase, showing her continued confidence in the crypto market.
Jack Dorsey’s Block is working to grow Bitcoin adoption through its subsidiaries. The company plans to launch a full Bitcoin banking suite designed for small businesses. This suite will use Block’s services, such as Cash App, Square, and Bitkey, to promote Bitcoin use.
Cash App supports the Bitcoin Lightning Network and generated $10 billion in Bitcoin revenue in 2024. Square enables merchants in the U.S. to accept Bitcoin payments. Bitkey offers self-custody hardware wallets for everyday users.
In the second quarter of 2025, Block added 108 Bitcoins to its corporate treasury, bringing its total holdings to 8,692 BTC, which were purchased at an average price of $30,405 per Bitcoin.
This makes the company a bigger supporter of Bitcoin. Meanwhile, Cathie Wood’s share purchase fits her plan to back companies that help grow crypto adoption.
