AI Rally in Full Swing... 'AMD' Top Executives Sell Off Billions in Shares

Advanced Micro Devices, Inc. (AMD) CEO Lisa Su sold 148,350 shares on the open market on May 13 under a pre-established Rule 10b5-1 trading plan, realizing approximately $66.2 million (about KRW 850 billion). She still directly holds roughly 3.02 million shares. Earlier, on April 24, CTO and Senior Vice President Mark Papermaster disposed of about 30,000 shares at around $350 per share—about $11 million (KRW 140 billion)—and on May 8, Vice President and CSO Paul Darren Grassby sold a similar amount on the market. The transactions by Su and Papermaster were both conducted under their respective Rule 10b5-1 plans and duly disclosed; all three executives continue to maintain significant AMD holdings.

In its first quarter 2026 financial results announced May 5, AMD reported revenue of $10.3 billion and net income of $1.4 billion, attributing its growth primarily to expanding demand for data-center AI infrastructure. Following the earnings release, AMD shares surged to an intraday record of $469.22 on May 11. By the morning of May 19, amid profit-taking and news of Su’s May 18 meeting with China’s vice premier, the stock gave back roughly 5 percent.

Headquartered in Santa Clara, California, AMD designs high-performance CPUs, GPUs and AI accelerators and is a leading competitor to NVIDIA in the data-center AI chip market. Since Su became CEO in 2014, she has driven expansion of the data-center and AI business with products such as the EPYC server processors and Instinct AI accelerators, and has recently ramped up large-scale AI infrastructure collaborations with major customers, including Meta.
