Musk’s xAI to Invest Over $20 Billion in Mississippi Data Center

xAI, the artificial intelligence company founded by Elon Musk, will invest more than $20 billion to build a large-scale data center in Southaven, Mississippi, state Governor Tate Reeves said on Thursday.

The investment comes as booming demand for generative AI drives tech companies to sharply expand computing infrastructure. Data centers have become a focal point for spending by AI startups and hyperscalers seeking to train increasingly powerful models.

According to the governor’s statement, xAI expects to begin operations at the Southaven data center in February 2026. Musk had previously announced on December 30 that xAI had acquired a data center named “MACROHARDRR,” saying the facility would lift the company’s total computing capacity to 2 gigawatts, though he did not disclose the investment size or location at the time.

The Southaven site is located near a power plant recently acquired by xAI and close to its existing data center footprint in Memphis, Tennessee, the statement said. Memphis is home to xAI’s flagship supercomputer cluster, Colossus, which the company has described as the largest in the world.

The expansion highlights xAI’s aggressive push to compete more directly with leading AI developers such as OpenAI and Anthropic, whose ChatGPT and Claude models dominate much of the current generative AI market.

xAI’s spending underscores the heavy cash demands of the AI race. Bloomberg reported earlier on Thursday that the company burned $7.8 billion in cash during the first nine months of the year, reflecting the high cost of advanced data center hardware and large-scale model training.

Nvidia CEO Urges UK to Boost Computing Power to Fully Harness AI Potential

Nvidia’s CEO Jensen Huang said on Monday that the UK currently lacks sufficient computing infrastructure to fully capitalize on its leading artificial intelligence research capabilities. Huang’s remarks coincided with the UK’s partnership with Nvidia to create a new AI testing environment aimed at fostering innovation.

Speaking during London Tech Week alongside Prime Minister Keir Starmer, Huang praised the UK’s top universities, startups, and its status as the world’s third-largest AI venture capital market. He welcomed Starmer’s plan to increase Britain’s domestic computing capacity by 20 times and inject £1 billion ($1.36 billion) in investments.

“The ability to build these AI supercomputers here in the UK will naturally attract more startups and empower the country’s vibrant research ecosystem,” Huang said, calling Britain “an incredible place to invest.”

The UK’s Financial Conduct Authority (FCA) launched a framework to enable financial firms to experiment with AI tools in a controlled environment starting this October. Partnering with Nvidia, the FCA will offer firms access to advanced computing resources, specialized AI expertise, improved datasets, and regulatory guidance.

Finance Minister Rachel Reeves emphasized the government’s commitment to removing regulatory barriers to economic growth, labeling it a “top priority.” Earlier this year, she expressed satisfaction with regulators’ efforts to reduce red tape.

Prime Minister Starmer also announced that Israeli fintech company Liquidity Group will open its European headquarters in London, committing to a £1.5 billion investment, further signaling the UK’s ambition to become a global AI and tech hub.

Britain Cancels $1.7 Billion of Computing Projects in Setback for Global AI Ambitions

The U.K. government has canceled £1.3 billion ($1.7 billion) in computing infrastructure projects, marking a significant setback to its goal of becoming a global leader in artificial intelligence (AI). The cancellations include two major taxpayer-funded initiatives:

1. AI Research Resource: A £500 million ($640 million) project aimed at enhancing the U.K.’s compute infrastructure for AI research.
2. Exascale Computer: An £800 million ($1.02 billion) commitment to develop a next-generation exascale computer at the University of Edinburgh, capable of performing one trillion calculations per second.

These projects were intended to bolster the U.K.’s high-performance infrastructure, essential for running advanced AI models requiring substantial computational power and data. However, the newly elected Labour government has decided to redirect these funds to other fiscal priorities, citing the need for difficult spending decisions across all departments to restore economic stability and support national growth.

Fiscal Challenges and Strategic Shifts

The decision comes in the wake of a projected £22 billion ($28 billion) of unfunded commitments inherited from the previous Conservative administration. British Finance Minister Rachel Reeves recently announced a series of spending cuts to address this fiscal challenge.

Despite the cancellations, the government launched an AI Opportunities Action Plan last month to identify ways to enhance the U.K.’s computing infrastructure and support its industrial strategy with AI and other emerging technologies.

Regulatory Approach and Future Plans

Prime Minister Keir Starmer’s government plans to introduce new statutory regulations for the AI industry, diverging from the previous administration’s stance of avoiding formal legislation to prevent stifling innovation. The move signals a shift in strategy as the U.K. navigates its AI ambitions under the new government.
