Elon Musk's xAI to Build World's Largest Supercomputer in Memphis, Tennessee

Elon Musk's xAI is planning to construct what could potentially be the world's largest supercomputer in Memphis, Tennessee. The project, known as the "Gigafactory of Compute," will be located in the vast 785,000 square feet former Electrolux manufacturing site, surpassing the combined power of the current top two supercomputers by four times. While xAI has not officially confirmed the development, reports indicate that the installation will incorporate 100,000 Nvidia H100 GPUs to enhance AI capabilities, including advancements for their AI chatbot, Grok, with an expected opening in fall 2025.

Despite facing competition from tech giants like Meta, who are also heavily investing in GPU acquisitions for their data centers, the Memphis project, subject to local approval, pledges substantial job creation and economic investment for the city, aligning with xAI's recent announcement of a $6 billion funding raise.

Key Takeaways

  • xAI, Elon Musk's startup, plans to build a supercomputer in Memphis, Tennessee, potentially the world's largest.
  • The supercomputer, dubbed "Gigafactory of Compute," is expected to be four times larger than the combined capacity of the world's top two supercomputers.
  • The facility will occupy 785,000 square feet in the former Electrolux manufacturing site, significantly larger than the current leading supercomputer, Frontier.
  • xAI aims to equip the center with 100,000 Nvidia H100 GPUs to train AI models, including new versions of its chatbot, Grok, by fall 2025.
  • Despite competition from other tech giants investing in AI data centers, xAI's project promises economic benefits and job creation for Memphis.


Elon Musk's xAI initiative in Memphis, Tennessee, could reshape global AI capabilities, leveraging a massive 100,000 Nvidia H100 GPUs. This expansion, driven by a $6 billion funding boost, aims to quadruple current supercomputing power, potentially outpacing rivals like Meta. Short-term, Memphis will see economic growth and job creation, while long-term impacts include accelerated AI development and increased global competitiveness in AI technology. The project's success hinges on local approvals and maintaining a technological edge in a rapidly evolving sector.

Did You Know?

  • Nvidia H100 GPUs: The Nvidia H100 GPU is a high-performance graphics processing unit designed for intensive computing tasks, particularly in the field of artificial intelligence and machine learning. It features advanced architectures like Tensor Cores that accelerate AI model training and inference, making it a critical component for supercomputers aiming to handle complex AI workloads.
  • Grok AI Chatbot: Grok is an AI-powered chatbot developed by xAI, designed to simulate human-like conversation and provide information or assistance through natural language processing. The term "Grok" itself comes from a science fiction novel by Robert A. Heinlein, meaning to understand something deeply and intuitively. In the context of AI, Grok represents a sophisticated level of interaction and comprehension.
  • Gigafactory of Compute: This term refers to a massive facility dedicated to housing and operating a supercomputer, analogous to Tesla's Gigafactories, which are large-scale manufacturing plants for electric vehicle batteries. The "Gigafactory of Compute" signifies a significant expansion in the scale of computing infrastructure, focusing on the production and deployment of computational power rather than physical products.
