Elon Musk's AI startup, xAI, is accelerating its computing power competition. On Tuesday, Musk announced that the company has successfully acquired a third building to expand its infrastructure in Memphis, Tennessee. The core goal of this expansion is to increase model training computing power to nearly 2 billion watts (2GW).

Musk confirmed on the social platform X that the new building is named "MACROHARDRR"—a name interpreted by the public as an open parody of industry giant Microsoft (Microsoft). Although Musk did not reveal specific coordinates, previous reports indicated that the location is outside Memphis and will serve as xAI's third large-scale data center.

xAI's current supercomputer cluster, "Colossus," is already recognized as the largest supercomputing cluster in the world. According to the latest plan, xAI is pushing for a large-scale expansion of "Colossus," with the ultimate goal of accommodating at least 1 million graphics processing units (GPUs). This ambitious hardware upgrade aims to compete directly with OpenAI's ChatGPT and Anthropic's Claude by training more advanced large models.

It is reported that xAI plans to start the renovation of the new building in 2026. This facility, along with the upcoming "Colossus 2," will be adjacent to the power grid of the Tennessee Valley Authority. This layout close to key energy facilities can provide the necessary power support for high-energy AI operations.

However, xAI's rapid expansion has also sparked controversy. Environmentalists point out that the operation of data centers consumes massive energy, and this high dependence on resources is triggering widespread public discussion about the environmental impact of large-scale artificial intelligence infrastructure.
