Google has filed to build another data center at its campus in Midlothian, Texas.

In a filing with the Texas Department of Licensing and Regulation (TDLR), Google - through the shell company Sharka LLC, which was behind the other data centers for Google at the site - has shared its plans for a fifth building on the data center campus.

Dubbed Sharka Data Center - Building 5, the construction project began in late January this year and is expected to be completed by February 24, 2027.

An estimated $880 million will be invested in the development, which will be a one-story data center spanning 288,000 sq ft (26,756 sqm). The investment will include the core, shell, and interior finish out, as well as site improvements.

The location of the project is listed as 3441 Railport Parkway in Ellis County, the same address as Google's Midlothian data center campus.

Google added a fourth building in 2024, revealing plans for a $100 million, 170,600 sq ft (15,850 sqm) data center at the site in March of that year.

Google first built a data center in the Midlothian area of DFW in 2019 through its Alamo Mission LLC shell company under the project name Sharka. After originally buying 375 acres, the company later acquired another 165-acre tract for further development.

Google launched a Texas cloud region in Dallas in June 2022.

Google is also developing a second Texas campus in the Red Oak area of Dallas.

In November 2025, Google revealed it would spend $40bn to expand its cloud and AI infrastructure in Texas through 2027. This included the expansion of its presence in Ellis County, along with announcing three new campuses in Armstrong and Haskell Counties, two of which would fall in the latter.

Elsewhere in Texas, and seemingly separate from the $40bn commitment, Google is backing the TeraWulf joint venture with Fluidstack that plans a data center in Abernathy, Texas.

Earlier this year, the cloud company revealed it was building a data center in Wilbarger County, Texas, that would be powered by onsite ‘clean energy’ from US energy firm AES.
