Amazon Missouri Data Center Campus Lands in Montgomery County With $10 Billion Commitment

The Amazon Missouri data center campus is a $10 billion development in Montgomery County, announced on 15 June 2026 and set to become one of the largest single private investments in the rural heart of the state. The project will be owned and operated by Amazon through its cloud arm, Amazon Web Services, and sits on the northeast quadrant of the Interstate 70 and Highway 19 interchange, near the communities of Montgomery City and New Florence in eastern Missouri. The campus is designed to host the high density computing infrastructure that powers cloud workloads, from remote work and video streaming to hospital records and financial transactions. Amazon confirmed the investment during a press conference attended by state, county, and utility leaders, with Governor Mike Kehoe framing it as a generational opportunity for the region. Local officials have referred to the development internally as “Project Green,” a codename used through the land use approval process before Amazon was publicly named. The company has committed more than $7 million in community contributions and will work with utility Ameren Missouri on grid connection. According to figures shared by the governor’s office and reported by Missourinet, the project is expected to create roughly 400 permanent data center jobs alongside thousands of construction roles. Amazon has not released a groundbreaking date or an operational timeline, and officials have said the build will take several years to complete.

Montgomery County Becomes a Data Center Cluster in Eastern Missouri

The Amazon data center cost of $10 billion places Montgomery County at the center of a fast forming data center cluster, a remarkable shift for a county better known for farmland than cloud infrastructure. Amazon’s campus will rise directly across the interstate from a separate Google project near New Florence, which carries a headline figure of $15 billion and is further along in construction. Together the two developments represent tens of billions of dollars flowing into a single rural county, a concentration rarely seen outside major metropolitan markets such as Northern Virginia or Phoenix. The scale of the Google site is even larger than first reported, with cost benefit filings indicating equipment investment could eventually reach far higher figures over the life of the project, as detailed in coverage by Broadband Breakfast. Missouri has emerged as a competitive destination for hyperscale operators, helped by available land, Chapter 100 tax incentive structures, and grid capacity. The surge in cloud demand is also reshaping the power supply side of the industry, with utility scale renewable builds such as the 104MW Ostrea Solar project in Washington illustrating the kind of generation capacity that large data center loads increasingly rely on. The trend extends beyond Montgomery County. A separate $6 billion data center project in Festus, roughly 90 miles away, reshaped local politics after residents ousted incumbents over transparency concerns, while a $1.4 billion campus was announced in Liberty. For a state that has historically trailed coastal technology hubs, the arrival of two of the world’s largest cloud providers within sight of each other signals a structural change in where America builds its digital backbone.

Amazon Missouri Data Center Timeline and What Comes Next

The Amazon Missouri data center timeline remains the biggest open question, as the company has declined to specify a construction start or an expected completion date and has confirmed only that the build will span several years. Before earthworks begin in earnest, the project must move past a legal challenge. A residents’ group, Preserve Montgomery County LLC, filed suit in February 2026 alleging that county officials violated Missouri’s Sunshine Law during the approval of the tax incentive package, and a hearing in the case is scheduled for early August, according to KOMU. Water use and rural character are at the heart of local concerns. Amazon has sought to address them by partnering with agricultural technology firm Arable Labs to improve irrigation efficiency for nearby farmers, a measure the company says will cut water use by 100 million gallons. Amazon will also host a public open house on 23 June where residents can question project experts on water and sound impacts. If the campus proceeds as planned, Montgomery County estimates it will generate hundreds of millions of dollars in new property tax revenue over the next 25 years.
