MP Materials to Build $1.3B Manufacturing Hub at AllianceTexas
The facility will produce rare earth magnets as part of a public-private partnership.
MP Materials will invest $1.25 billion to build a rare earth magnet manufacturing facility in Northlake, Texas. Known as 10X, the manufacturing hub will be located on Hillwood’s AllianceTexas campus.
The facility will occupy multiple buildings on a 120-acre site. Construction is scheduled to begin “imminently,” MP Materials said, and commissioning is expected to begin in 2028.
Once complete, 10X will employ 1,500 people and have a production capacity of about 10,000 metric tons of rare earth magnets per year.
The project is being supported by the state of Texas, Denton County and the city of Northlake, which are collectively offering a $200 million incentive package over 10 years. The incentives include grants, abatements and exemptions. Also part of the package are more than $66 million in grants from the Texas Enterprise Fund and Texas Semiconductor Innovation Fund.

10X is part of MP Materials’ July 2025 public-private partnership with the U.S. Department of Defense to establish more domestic rare earth magnet production. Rare earth magnets are crucial production parts for drones, robots, data centers and semiconductor fabrication.
10X is located 10 miles from MP’s existing manufacturing facility in Fort Worth, Texas. CBRE led the site selection process for the new project.
Continuing growth at AllianceTexas
Hillwood continues to expand and make deals at its 27,000-acre, master-planned AllianceTexas campus. Overall, the mixed-use property comprises 60 million square feet of completed and underway buildings, with assets including residential, retail, office and industrial spaces.
Earlier in February, the company announced it would start construction on Alliance Westport, a 1.2 million-square-foot industrial building on the campus. Construction is expected to finish in the first quarter of 2027.
Hillwood currently has four other speculative industrial buildings in development within AllianceTexas development, totaling more than 3.4 million square feet. Two of them, the 798,494-square-foot Alliance Westport 15 and the 310,036-square-foot Alliance Gateway 34, broke ground in September. Both facilities are slated to come online this year.
The Dallas-Fort Worth metro led the nation for industrial development activity as of January 2026, according to a Yardi Matrix report. The Metroplex recorded about 28.8 million square feet of industrial space under construction, representing 2.8 percent of existing stock.
