Elon Musk Supercharges AI Ambitions with Massive GPU Expansion in Memphis

Elon Musk continues to intensify the AI arms race with the news that Tesla and xAI will keep purchasing chips from semiconductor giants NVIDIA and AMD. This development underscores the critical role high-performance GPUs play in advancing artificial intelligence and autonomous driving technologies. Musk, the CEO of Tesla and founder of xAI, disclosed these intentions during a recent interview.
Both Tesla and xAI are already extensively utilizing GPUs from NVIDIA, demonstrated by the Colossus supercomputer in Memphis, Tennessee, which has been instrumental in training xAI's Grok 3 models. Originally built with 100,000 NVIDIA H100 GPUs, the capacity of the Colossus supercomputer was expanded to 200,000 GPUs earlier this year, indicating the scale at which these companies operate.
Looking forward, Musk revealed ambitious plans for xAI to construct a new facility near Memphis, which will house a staggering one million GPUs. This development marks Memphis as a crucial hub for future computational endeavors, reinforcing the city’s importance in Musk's vision for a tech-rich manufacturing base.
Musk further detailed that besides AI and self-driving technology, the high-performance GPUs are also crucial for training Tesla's humanoid robot, Optimus. He emphasized the reliance on NVIDIA's leading GPUs for their superior performance, which directly contributes to their procurement strategy.
The announcement of Musk's Memphis-based plans has been met with mixed reactions. While local officials praise the move as transformative for the region’s tech industry, environmental groups express concerns about the facility's dependency on natural gas turbines, linking them to potential air quality violations and health risks.
Musk's comments reflect a broader narrative about the constraints facing AI progression, suggesting that the current bottleneck—chip availability—will transition to electrical power supply issues by mid-2026. While acknowledging China’s investment in energy, he maintained that the U.S. holds a cultural edge in breakthrough innovation.
