ARK Invest Adds $40.8 Million in Block and Circle Shares

Cathie Wood’s Ark Invest uses actively managed exchange-traded funds to target companies associated with disruptive innovation. Coinbase Global provides cryptocurrency trading and custody services, while Circle Internet Group operates the USDC stablecoin. Their shares give Ark exposure to two key parts of the digital-asset industry — trading infrastructure and blockchain-based payments — making the firm’s portfolio moves a closely watched gauge of institutional appetite for crypto-linked equities.

On Aug. 3, Ark bought 54,776 Coinbase shares worth about $8.02 million at the closing price and 23,070 Circle shares valued at roughly $1.39 million, taking the combined purchase to about $9.41 million. The trades were spread across the ARK Innovation ETF, ARK Next Generation Internet ETF and ARK Fintech Innovation ETF. Coinbase edged up 0.16% to $146.50, while Circle fell 3.61% to $60.35. Ark also made smaller reductions in Solmate across the funds as it rebalanced portfolio weights.

Shares of USDC issuer Circle have recently come under pressure from factors including the launch of rival stablecoin Open USD. ARK Invest, founded by Cathie Wood, has nevertheless made a substantial purchase, signaling strong long-term confidence in digital finance and the stablecoin market. The move also reflects the firm’s core buy-the-dip strategy and offers a gauge of the stablecoin industry’s prospects and technology-stock investment trends.

ARK Invest added to its position again on July 15, 2026, with its funds spending about $13.9 million to buy 220,012 Circle shares while selling 27,742 Robinhood shares. Despite competition from the new Open USD stablecoin, analysts maintained an outperform rating on Circle.

Cathie Wood’s ARK Invest runs actively managed ETFs focused on disruptive innovation and buys into market declines to maintain portfolio weightings. Coinbase, Circle, Bullish and Robinhood span exchanges, stablecoins and retail brokerage, making them key gauges of crypto-finance infrastructure. Wood has also argued that inflation is cooling and monetary policy could ease, citing annual unit labor cost growth of just 0.5%.

On June 25, 2026, ARK bought 9,014 Coinbase shares, 9,264 Circle shares, 9,136 Bullish shares and 35,023 Robinhood shares through ARKK, ARKW and ARKF. The purchases were worth an estimated $5.4 million based on that day’s closing prices. ARK stepped up its buying over the full month, purchasing about $44 million of Coinbase, $25.25 million of Circle and $8.2 million of Bullish shares. Circle fell 40% in June.

Bullish is a cryptoasset trading platform serving institutional investors. It listed on the New York Stock Exchange in August 2025 at $37 a share and holds about 24,300 Bitcoin. The company also acquired British share registrar Equiniti for $4.2 billion in an effort to connect regulated shareholder services with tokenization technology, making it a closely watched proxy for the crypto market and blockchain-based financial infrastructure.

Cathie Wood’s Ark Invest bought 122,020 Bullish shares worth about $4.4 million through three ETFs on May 18 and 19, 2026. By May 21, it had purchased the stock for four consecutive days, spending a total of $12.5 million. Bullish posted a first-quarter net loss of $604.9 million, while adjusted revenue rose 49% from a year earlier to $92.8 million. The shares closed at $35.96 on May 21.

Circle Internet Group issues USDC, the world's second-largest U.S. dollar stablecoin, and its business is closely tied to interest rates, stablecoin usage and regulatory developments. Cathie Wood's ARK Invest has increased its holdings again, reflecting a major growth fund's bet on digital-dollar infrastructure and Circle's future expansion.

Circle reported first-quarter earnings on May 11, 2026, posting earnings per share of 21 cents, above market expectations. ARK Invest bought 41,904 shares that day through ARKK, ARKW and ARKF, spending $5.5 million. Circle shares closed 16% higher at $131.76, their highest close since March 18. It was ARK's first increase in its holdings since spending $16.3 million on March 24.

Coinbase is a major U.S. cryptocurrency exchange, while Robinhood began as a zero-commission brokerage and has expanded its crypto business. Both companies’ shares are highly sensitive to market risk appetite and trading volumes. Cathie Wood’s Ark Invest uses actively managed ETFs to invest in disruptive innovation, and its decision to buy amid a geopolitical shock reflects a long-term bet on the growth of crypto-related stocks.

Ark Invest bought 22,452 Coinbase shares through ARKK, ARKW and ARKF on March 3, 2026, worth about $4.1 million based on the closing price of $182.36. It also purchased 158,587 Robinhood shares, worth about $12 million at $76.07 each. The stocks fell 1.55% and 3.44%, respectively, that day, and details of the trades were disclosed the following day, March 4.
