Nvidia Rubin architecture ramp expected to face massive supply shortage without 50% to 100% capacity increase

Industry reports suggest a significant supply gap is expected when Nvidia begins production of its Rubin architecture, requiring a 50% to 100% increase in capacity to meet demand.
Context
The upcoming ramp of Nvidia's next-generation Rubin architecture is expected to trigger a massive supply shortage unless manufacturing capacity increases by 50% to 100%. This supply crunch is driven by the extreme technical complexity of the Rubin R100 GPUs, which require advanced CoWoS-L packaging and HBM4 memory. Despite TSMC aggressively expanding its advanced packaging output toward a target of 150,000 wafers per month by late 2026, Nvidia has already secured approximately 60% of this total capacity, leaving competitors to scramble for remaining resources.
To prioritize the Vera Rubin platform, Nvidia has reallocated capacity away from existing chips, including halting production of China-bound H200 processors. The shortage risk is amplified by the scale of planned deployments, such as Microsoft's next-generation AI superfactories which aim to integrate hundreds of thousands of Vera Rubin Superchips. For investors, the bottleneck has shifted from raw silicon fabrication to high-end assembly and HBM4 availability, making supply chain throughput the primary factor for Nvidia's 2026 revenue ceiling.
