ARK Invest Shifts to AI, Sells Block and Robinhood

Cathie Wood's ARK Invest made significant portfolio adjustments in early August 2025, notably selling $4.8 million of Block Inc. shares ahead of its Q2 earnings and after the company's addition to the S&P 500, as well as acknowledging its fintech innovations like Bitchat. Simultaneously, ARK purchased about $4.2 million in Nvidia shares across several ETFs, reinforcing Wood's conviction in AI as a central investment theme and Nvidia’s role in AI infrastructure. ARK also increased its holdings in Advanced Micro Devices (AMD) with a $4.1 million acquisition, reflecting optimism prior to AMD’s earnings report. ARK reduced exposure to Robinhood by selling over $1.3 million in shares following the company's strong Q2 results, reallocating funds towards AI sector leaders. These moves highlight ARK's strategy of focusing on high-conviction, innovation-driven stocks and reducing fintech exposure amid market volatility. The changes demonstrate a continued pivot towards AI and semiconductor investments.
