Amazon Web Services data center campus at the Madison County Mega Site near Canton
Also called: AWS Madison Mega Site, AWS Canton campus
Amazon runs five large data center buildings at the Madison County Mega Site near Canton, part of a $10 billion plan first announced in 2024. In 2026 the county and Amazon disagreed over how much the buildings are worth for taxes. Amazon says this site cools with recycled wastewater.
Where things stand: Five buildings are running; Madison County taxed each one for 2026.
🕒 Latest update (Aug 17, 2026): Madison County supervisors set a value of about $292 million on each of the five Canton buildings; Amazon had argued for about $70 million each.
