Amazon purchases $65M data center site in Manassas

Amazon.com recently paid $65 million to purchase a 7.66-acre data center campus in Manassas, according to Prince William County property records.

Manassas Technology Partners, an affiliate of California-based Menlo Equities, sold the property at 7505 Mason King Court to Amazon Data Services on March 26.

County records show the property includes a 109,543-square-foot facility built in 2003.

Amazon and Amazon Web Services did not immediately return requests for comment regarding plans for the property. Datacenters.com identifies the site as AWS IAD7, a data center operated by Amazon Web Services.

Before Menlo acquired the property in September 2021 for $53 million, the site was owned by a limited liability company tied to Austin, Texas-based Digital Realty.

According to a 2009 U.S. Securities and Exchange Commission filing, Digital Realty acquired 7505 Mason King Court in 2008 for approximately $10.6 million.

The filing states that, upon closing, the company signed a lease for 100% of the building with a “leading IT enterprise company,” beginning in January 2009. The filing did not identify the tenant.

Menlo Equities also did not immediately return requests for comment.

In November 2025, Amazon announced plans to invest up to $50 billion to expand artificial intelligence and supercomputing infrastructure for Amazon Web Services’ federal cloud customers. Starting this year, AWS said it would begin constructing advanced data centers capable of adding nearly 1.3 gigawatts of AI and supercomputing capacity to support AWS Top Secret, AWS Secret and AWS GovCloud (U.S.) platforms.

It remains unclear how much of that investment will ultimately be directed toward Virginia infrastructure.

The AWS US East (Northern Virginia) Region launched in 2006 and operates data centers across Loudoun, Fairfax and Prince William counties. According to the most recently released company figures, AWS invested $63.9 billion in Virginia data centers between 2011 and 2022. AWS has said those investments added an estimated $21.3 billion to Virginia’s gross domestic product and supported 16,600 jobs.

In 2023, AWS separately announced plans to invest an additional $35 billion in Virginia by 2040 to establish multiple data center campuses across the state, a effort expected to create roughly 1,000 jobs. An Amazon spokesperson confirmed in November that the newer $50 billion AI infrastructure initiative is separate from the previously announced Virginia investment.
