In June, Elon Musk announced that Memphis, Tennessee, would be home to his ambitious “Gigafactory of Compute,” a massive supercomputing facility dedicated to training “Grok,” a large language model developed by Musk’s xAI. Now dubbed “Colossus,” this facility has rapidly positioned itself as the world’s largest AI compute cluster, signaling Memphis’s emergence as a major player in digital technology and AI development. In just over four months, Colossus became operational, and plans are already underway to double its capacity to 200,000 GPUs, further solidifying its impact on the region.
This rapid development has not only sparked interest but has also positioned Memphis as what local leaders are calling a “Digital Delta.” Memphis Mayor Paul Young celebrated the investment as proof of the city’s “get-it-done attitude,” and Ted Townsend, CEO of the Greater Memphis Chamber, heralded it as the largest capital investment by a new-to-market company in Memphis history. Townsend noted that Colossus positions Memphis on the “leading edge of artificial intelligence,” a statement that speaks to the broader economic and technological implications for the region.
In support of xAI’s expanding footprint, the Economic Development Growth Engine (EDGE) for Memphis and Shelby County recently approved an extension of land usage for xAI, providing an additional 522 acres south of the city for the next 21 years. The approval highlights the city’s commitment to supporting Musk’s vision, which extends beyond technology to community engagement and corporate responsibility.

However, the development has not been without controversy. Environmental advocates have voiced concerns over Colossus’s substantial water and energy requirements, along with air pollution from gas turbines temporarily used to meet the facility’s power needs. Some locals worry about worsening air quality, while others question the project’s long-term sustainability.
For insights on the development, Area Development spoke with Troy Parkes, Vice President of Global Development at the Greater Memphis Chamber, who underscored the strategic importance of “speed and power” in xAI’s site selection. Musk’s decision to forgo public incentives was driven largely by the need for rapid deployment and confidentiality. “We were in competition with eight other communities,” Parkes explained, “and Memphis was the only one to present a viable solution and critical path for their timelines.”
Addressing environmental concerns, Parkes emphasized xAI’s commitment to responsible resource management, noting initial steps to mitigate impacts on Memphis’s water supply. “They brought in water from outside sources, deliberately avoiding the local aquifer,” Parkes explained, acknowledging Memphis’s unique water quality. In collaboration with local leaders, xAI is also exploring plans for a large-scale water reclamation facility, aiming to set a new standard in sustainable water usage.

On the issue of power, Parkes acknowledged that the gas turbines supporting Colossus are temporary and will only operate until xAI determines the facility’s permanent energy requirements. He highlighted Musk’s interest in energy storage solutions that may eventually allow Colossus to operate independently from the local grid or even supply power back to it during high-demand periods, such as during storms.
“xAI is doing things purposefully to become a better corporate citizen,” Parkes emphasized, commending the company’s unique commitment to environmental stewardship. He closed with praise for xAI’s swift execution, saying, “They achieved in 122 days what would typically take years. It’s a remarkable accomplishment.”
Despite the divided public opinion, Memphis leaders remain optimistic about the partnership’s future. Parkes and the Memphis Chamber aim to foster this relationship, finding innovative solutions to support xAI’s growth and positioning Memphis as a central hub in the digital economy.
