Ark Invest Adds $9.4 Million of Coinbase and Circle Shares

Cathie Wood’s Ark Invest has made Circle Internet Group and SpaceX central bets on two fast-growing themes: regulated digital-dollar infrastructure and the commercial space economy. Circle issues USDC, while Elon Musk-led SpaceX combines launch services, Starlink connectivity and an expanding AI infrastructure push. Their rise among ARK’s top positions underscores the manager’s high-conviction approach, but also increases portfolio exposure to richly valued, volatile growth companies.

In trades disclosed on Aug. 5, 2026, ARK Invest bought about $17 million of Circle shares and roughly $20 million of SpaceX, extending its buying after SpaceX’s first quarterly report as a public company on Aug. 4. SpaceX said second-quarter revenue rose 92% to $7.81 billion, but the company posted a $541 million net loss and $18.4 billion in capital spending. The outlay, much of it tied to AI infrastructure, renewed concerns over cash burn despite stronger sales.

ARK Invest, led by Cathie Wood, uses actively managed funds including ARKK, ARKW and ARKF to hold crypto-linked equities and rebalance exposure as prices and portfolio weights shift. Bitmine Immersion Technologies is an Ether treasury company, while Block, Coinbase, Circle Internet Group and Bullish span payments, exchanges and stablecoin infrastructure. Changes in those positions are closely watched as a gauge of ARK’s risk appetite in a volatile corner of the equity market.

On July 28, 2026, ARK sold shares of Bitmine, Bullish, Block and Robinhood as crypto stocks weakened, while buying about $14.5 million of SpaceX and adding Nvidia. The rotation continued on July 29: ARK disposed of roughly $4.4 million across those four crypto-linked names and purchased about $14.5 million of Coinbase and Circle shares. The back-to-back disclosures showed the manager trimming selected crypto proxies while redirecting capital toward space, AI chips, a major exchange and a stablecoin issuer.

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.
