Musk Accelerates Colossus 2 Expansion with New Tennessee Sites Amid Legal Backlash

Key points

• Musk announced the addition of two new facilities to the Colossus 2 campus in Tennessee, naming them 'Spam' and 'Gun Range'.
• The 'Spam' site previously housed Hormel-brand products, while the 'Gun Range' location was formerly owned by the local police department.
• Musk stated that the Gun Range site is on track to be operational by the end of November 2026, with the Spam site following in December.
• A US District Judge recently denied xAI and its subsidiary MZX Tech a motion to dismiss a lawsuit filed by the NAACP.
• The lawsuit alleges that xAI is unlawfully operating unpermitted methane gas turbines in Southaven, Mississippi, to power the complex.

Background

Colossus 2 is an expansion of the original Colossus supercomputer built in Memphis in 2024 to support xAI's Grok chatbot. The project has faced significant local opposition, with residents staging protests and filing petitions against the facilities. This expansion follows a period of intense scrutiny on AI infrastructure, including broader debates on safety risks and environmental impacts.

Why it matters

The rapid physical expansion of AI data centers highlights the immense energy and infrastructure demands of modern artificial intelligence. The legal challenges regarding unpermitted power generation suggest that regulatory hurdles may increasingly constrain the speed at which tech giants can deploy their computing capabilities.

What to watch

The operational status of the Spam and Gun Range sites will be monitored in late 2026. The outcome of the NAACP lawsuit regarding the unpermitted gas turbines in Mississippi will likely determine whether xAI faces regulatory penalties or operational restrictions.
