Key factory construction initiatives to keep an eye on in 2026.

U.S. manufacturing construction spending declined after a peak in 2024, with over $32 billion in clean energy projects canceled in 2025 due to funding cuts and tariffs. However, major companies like Taiwan Semiconductor and Micron have announced significant investments, with Micron committing $200 billion for new facilities and R&D across multiple states. Other notable investments include Samsung's $17 billion semiconductor plant in Texas, Stellantis's $13 billion expansion in the Midwest, and Lilly's $27 billion investment in new pharmaceutical facilities.
