AISummary
SemiAnalysis says more than 24GW of datacenters are in advanced construction for delivery in 2027, across about 40 campuses. It cites over $1 trillion of binding datacenter leases signed year-to-date in 2026 and says modular designs are cutting build timelines.
AIWhy it matters
The report pairs leasing data and construction starts with a supply-chain view, showing how buildout pace may be checked against independent indicators rather than hunches.
