The United States is experiencing the largest wave of data center construction in its history. According to Blackridge's global data center market report, the U.S. has more than 4,000 operational data centers and hundreds of new facilities under development and the U.S. remains the world's largest digital infrastructure market.

The largest upcoming data center projects in the US are Meta Hyperion in Louisiana, Project Jupiter in New Mexico, xAI's MACROHARDRR in Mississippi, Galaxy Helios Campus in Texas, and Stargate Frontier in Texas. These data centers represent some of the largest data center developments ever announced, with individual investments reaching tens of billions of dollars and power requirements comparable to those of small cities.

In this article, we explore the Top 15 Largest Data Center Projects in the United States (US) by investment value, planned capacity, scale, and strategic importance.

List of Top 15 Largest Data Center Projects in United States (US) by Capacity 2026

Meta Hyperion AI Campus

Meta is developing the Hyperion AI Campus in Richland Parish, Louisiana, as one of the largest artificial intelligence data center projects ever announced in the United States. Backed by an estimated USD 27 billion investment, the campus spans more than 3,600 acres near Holly Ridge and Rayville and is planned to deliver up to 5 GW of power capacity upon full build-out. The development will provide approximately 4 million square feet of data center space and is being constructed in phases from 2025 through 2030. 

In late 2025, Meta formed a joint venture with Blue Owl Capital, which holds an 80% ownership stake while Meta retains 20% and manages construction and operations. The largest data center campus by Meta is designed to support large-scale AI training, inference, and supercomputing workloads using hundreds of thousands of next-generation GPUs. 

To meet its enormous power requirements, Meta is deploying a behind-the-meter energy strategy that combines on-site natural gas generation with up to 1.5 GW of solar capacity, creating a dedicated power ecosystem for the facility. In May 2026, the state of Louisiana announced USD 3.3 billion in tax breaks for Meta to build Hyperion AI Campus.

Project Jupiter (Stargate)

Project Jupiter is a planned 2.45 GW AI data center campus under development in Santa Teresa, New Mexico, near the Texas border. Developed by STACK Infrastructure and BorderPlex Digital Assets, the project serves as a major component of OpenAI's Stargate initiative and is expected to support Oracle's large-scale AI computing operations. 

The campus will consist of four hyperscale data center buildings and is backed by an estimated investment of up to USD 165 billion as part of the wider Stargate ecosystem. To support its enormous power requirements, the facility will operate on a dedicated microgrid powered by Bloom Energy fuel cells rather than relying solely on traditional grid infrastructure. 

The project also incorporates closed-loop, non-evaporative data center cooling technology to minimize water consumption while supporting next-generation AI training and inference workloads.

xAI MACROHARDRR

xAI is developing MACROHARDRR, a hyperscale AI data center campus in Southaven, Mississippi, within the Greater Memphis market. The project is being built inside an 810,000-square-foot warehouse at 2400 Stateline Road West and represents an investment exceeding USD 20 billion. Developed and operated by xAI, the facility forms part of the company's rapidly expanding AI infrastructure network that supports training and inference workloads for its Grok models. 

Retrofitting and construction activities of the largest data center project in Mississippi began in early 2026, with initial operations already rolling out. Combined with xAI's surrounding regional assets, MACROHARDRR is expected to contribute to a broader AI computing platform approaching 2 GW of capacity, making it one of the largest AI-focused infrastructure developments currently underway in the United States.

Galaxy Helios Campus (Expansion)
