Cathie Wood’s ARK Invest expanded its stake in the Bullish crypto exchange on Monday, purchasing approximately 238,000 shares worth around $12 million across its flagship exchange-traded funds (ETFs).
According to ARK’s daily trade disclosures, the ARK Innovation ETF (ARKK) bought 164,214 shares, the ARK Next Generation Internet ETF (ARKW) added 49,056 shares, and the ARK Fintech Innovation ETF (ARKF) acquired 25,076 shares.
The latest purchase follows ARK’s buying activity last week, when the firm added over $5 million worth of Bullish shares across multiple ETFs. Since Bullish’s $1.1 billion debut on the New York Stock Exchange, ARK has accumulated roughly $172 million in the company’s stock across its funds.
Bullish Records Surge in Options Trading Volume
ARK’s renewed buying comes as Bullish reported more than $82 million in trading volume within just five days of launching its crypto options platform. The new product lets users deploy their entire portfolio as collateral across spot, futures, and options markets, improving capital efficiency and drawing strong market interest.

Institutional partners such as FalconX Global, Wintermute, and BlockTech took part in the launch of Bullish’s new options platform. “We’ve built a product designed to address the key pain points in today’s crypto options trading landscape,” Bullish wrote on X Monday.
Bullish shares closed the day at $50.26, down 0.71%, with after-hours trading showing a slight decline to $50.02.

Bullish Expands to 20 U.S. States
Last month, Bullish officially launched operations in 20 U.S. states after securing both a BitLicense and a money transmission license from the New York State Department of Financial Services (NYDFS) — a key regulatory milestone for any crypto firm.
The exchange began its U.S. rollout with two major institutional partners, BitGo and Nonco. Founded in 2021, Bullish has since processed more than $1.5 trillion in global trading volume and now ranks among the top 10 exchanges by Bitcoin and Ether activity.
