ARK Invest Sells $75M in AMD, Buys Nvidia and Broadcom in AI Strategy Shift

Cathie Wood's ARK Invest has adjusted its artificial intelligence portfolio, selling a substantial position in Advanced Micro Devices while increasing its holdings in semiconductor giants Nvidia and Broadcom. The trades, executed on August 28, 2026, signal a strategic rotation toward established AI infrastructure providers.

Details of the Portfolio Rotation

According to disclosed fund transactions, ARK executed the following trades on August 28, 2026:

• Sold: 156,286 shares of Advanced Micro Devices (AMD) for approximately $74.5 million.
• Bought: 243,707 shares of NVIDIA Corporation (NVDA) for approximately $55.56 million.
• Bought: 55,131 shares of Broadcom Inc. (AVGO) for approximately $20.48 million.

The combined purchases of Nvidia and Broadcom totaled $76.04 million, slightly exceeding the proceeds from the AMD sale. This indicates a reallocation of capital within the semiconductor sector rather than a reduction in overall exposure.

A Bet on AI Infrastructure

The portfolio adjustment reflects a shift in conviction toward companies at the core of AI infrastructure. By trimming its AMD position, ARK is reducing exposure to a key challenger in the AI chip market and scaling up its bet on two distinct pillars of the AI ecosystem.

Nvidia represents the dominant platform for accelerated computing, while Broadcom provides critical exposure to custom AI chips and high-performance networking equipment. These components are in high demand from hyperscale data center operators building out their AI capabilities.

What This Means for Investors

This series of trades suggests ARK is concentrating its AI investment thesis on market leaders with established ecosystems and infrastructure leverage. The timing of the Broadcom purchase is also notable, occurring shortly before the company's scheduled earnings report on September 2, 2026.

While these moves offer insight into ARK's strategic thinking, they should not be viewed as a direct trading signal. Fund transactions are often influenced by factors specific to the portfolio, such as rebalancing needs, liquidity management, or tax considerations. For market observers, the key takeaway is the direction of institutional preference within the high-stakes AI sector, underscoring a continued, but more concentrated, bullish stance on the companies powering the build-out of artificial intelligence.
