Ark Invest invests over $16 million to buy more Coinbase and Robinhood shares

Cathie Wood’s Ark Invest continues to increase its holdings in crypto-related stocks amid global market volatility due to US–Iran tensions.

According to the trading records released on Tuesday, Ark purchased a total of 22,452 Coinbase shares through three ETFs: ARKK, ARKW, and ARKF. At a closing price of $182.36 per share, the transaction was worth approximately $4.09 million.

On the same day, the company also bought an additional 158,587 Robinhood Markets shares, valued at around $12.06 million based on the closing price of $76.07.

This move comes as both stocks declined due to geopolitical instability related to US–Iran conflict, which put pressure on the stock market. The Nasdaq Composite fell 1%, while the S&P 500 dropped 0.94% on Tuesday. Coinbase shares declined 1.55%, and Robinhood fell 3.44%.

Despite the short-term correction, the buying activity indicates that Ark maintains a long-term positive outlook on platforms tied to the digital asset ecosystem. Since early 2026, the firm has been continuously rebalancing its portfolio, taking advantage of dips to increase positions in Coinbase, Robinhood, and also adding shares of Circle and Bullish.

According to its investment strategy, Ark limits each stock’s weight to about 10% within a fund to ensure diversification, which necessitates rebalancing when market fluctuations alter these weights.

As of March 3, Coinbase is the sixth-largest holding in the ARKK fund, with a 4.21% allocation, worth approximately $281.2 million. Robinhood ranks seventh with 4.07%, and Circle is eighth with 4.05%.
