Nvidia Dominates AI System Control Share, Driving Premium Valuation
The market values Broadcom (AVGO), Advanced Micro Devices (AMD), and Nvidia (NVDA) differently due to their distinct roles in the AI stack. This disparity can be attributed to one key metric: AI system control share.
AI system control share represents the portion of AI revenue a company earns from selling full platforms, including hardware, software, and reference architectures. In other words, it's the percentage of AI revenue that comes from companies selling entire systems, not just individual components.
Nvidia holds the highest share of AI system control, with its data center business generating over $80 billion in revenue in the first half of fiscal 2026. This is due in part to Nvidia's dominance in the market, with its data centers accounting for over 90% of total sales.
Broadcom sits at the opposite end of the spectrum, designing custom AI accelerators and high-speed switches for hyperscalers. While Broadcom has reported significant growth in AI semiconductor revenue, its chips often carry other brands and are used under the customer's name. This gives Broadcom strong contract-backed revenue but a lower AI system control share.
AMD falls somewhere in between Nvidia and Broadcom, offering its own platform that can define some deployments. While AMD has made strides in recent years, it still lags behind Nvidia in terms of market recognition and investor appeal.
