Elon Musk announced xAI has purchased a third building called MACROHARDRR near its Colossus data center in Memphis to expand AI training compute capacity to nearly 2 gigawatts. The aggressive expansion aims to house at least 1 million Nvidia GPUs as xAI races to compete with OpenAI and Anthropic, while raising billions to fund infrastructure that critics say consumes massive energy.

xAI Purchases Third Building to Expand AI Training Compute Capacity

Elon Musk revealed Tuesday that xAI has acquired a third building to expand its infrastructure near Memphis, Tennessee, pushing the company's AI compute power to nearly 2 gigawatts of compute power

2

. The billionaire posted on X that the new structure will be named MACROHARDRR, an extension of his Macrohard project where he intends to build software from the ground up using AI agents

1

. The term is potentially a play on Microsoft's name

3

. Located in nearby Southaven, Mississippi, the MACROHARDRR building adjoins the Colossus 2 facility currently under construction

2

. A gigawatt is enough to provide electricity for about 750,000 US homes, meaning the expanded capacity could power approximately 1.5 million homes

Memphis Expansion Targets Million GPU Supercomputer Infrastructure

The latest Memphis expansion underscores xAI's ambitious push to compete with OpenAI and other industry leaders by training advanced AI models at unprecedented scale

3

. xAI is planning to expand its supercomputer Colossus to house at least 1 million graphics processing units

5

. The Colossus data center in Memphis is already touted as the largest supercomputer cluster in the world

5

. Musk posted earlier this year that Colossus 2 will eventually house 550,000 chips from Nvidia Corp., which would cost tens of billions of dollars

2

. Nvidia has already reportedly signed a deal to deliver the needed Nvidia GPUs for the site, helping Musk reach his goal of acquiring 50 million H100-equivalent GPUs in the next five years

1

. Nvidia CEO Jensen Huang called the first Colossus project a "superhuman" effort, especially after the facility began operation after just 19 days—a feat that usually takes four years

Natural Gas Power Plant and Fundraising Drive Infrastructure Growth

The startup is planning to start turning the newly purchased warehouse into a data center in 2026, with both the new data center and Colossus 2 located close to a natural gas power plant that xAI is building in the area, as well as other power sources

5

. Musk has already confirmed that xAI bought an overseas power plant and is shipping it to the U.S. to power Colossus 2, and the company has set its sights on installing a gas turbine facility set to supply 460MW from natural gas

1

. Even though Elon Musk is one of the richest people on earth, he's working to raise tens of billions of dollars to help fund the project, as xAI is burning through over a billion dollars a month

1

. xAI was in talks to raise $20 billion in debt and equity earlier this year, in part to buy Nvidia processors for Colossus 2

2

. The company previously raised $10 billion in capital through equity funding and loans in July, and has held talks with Saudi Arabia's PIF sovereign wealth fund over a further $20 billion raise that would bring its value to over $170 billion

Environmental Concerns Mount as Data Centers Demand Massive Energy

The expansion of AI infrastructure has drawn criticism from environmental activists as data centers consume large amounts of energy

3

5

. Environmental concerns extend beyond power consumption, as xAI expects to use millions of gallons of water per day at the site for cooling servers and infrastructure

4

. However, xAI has taken steps to reduce its environmental footprint by announcing in February a plan to build a new wastewater treatment center near Colossus at a cost of around $80 million, which will enable the company to reuse approximately 13 million gallons of wastewater per day

4

. Musk's ultimate goal is to have more AI compute than everyone else combined, challenging Microsoft and other AI titans

1

. Although xAI is a relatively new entrant founded in 2023 to compete with OpenAI's ChatGPT and Anthropic's Claude, it quickly caught up with more established players due to the significant resources being poured into the project

1

4

. With other players in the AI game also spending billions of dollars on their own projects, the question remains where all this expenditure will ultimately lead as the race to build the most advanced AI on the planet intensifies
