Mark Lipacis

Mark Lipacis is a senior semiconductor analyst at Jefferies, covering major semiconductor companies with particular focus on the AI computing acceleration theme and data center chip demand. His research on NVIDIA's AI chip market position, the data center GPU market, and semiconductor cycle timing has been highly influential as AI computing demand transformed the semiconductor sector beginning in 2023. He analyzes the full stack of semiconductors involved in AI training and inference — from GPUs to memory to networking chips — providing institutional investors with a comprehensive framework for understanding the AI semiconductor investment opportunity and risks. His work on supply chain dynamics, wafer allocation at TSMC, and long-lead equipment ordering patterns has helped institutional investors anticipate semiconductor cycle inflections before they become visible in company results — a critical edge in a sector where lead times for capacity additions run 18 to 24 months ahead of revenue recognition.
