Amazon Data Services has acquired 100 acres in Chantilly as part of a $73 million deal, according to land records.
Multiple media outlets have indicated the site will be used for data centers.
The Washington Business Journal first reported earlier this month that H&M Gudelsky Asset Management LLC sold the land shortly before Christmas for well over the assessed value of nearly $3.5 million.
The site borders the boundary line of Fairfax and Loudoun counties, sitting north of Route 50.
The land is zoned Mineral Resource/Heavy Industry (MRHI) and has been owned by the company since 2004.
In July, Amazon Web Services acquired nearly 90 acres near Arcola for $116 million.
Loudoun County is home to more than 70 data centers, with most of them falling in the Ashburn corridor that has become known as "Data Center Alley."
