At least 17 data center projects were canceled in the US during Q3 2026, the highest quarterly total since 2024, according to tracking site Programs. At least four additional projects have been scrapped since October, bringing cancellations in the second half of this year close to matching the full-year 2025 total. Local resident opposition remains the leading cause of cancellation, accounting for roughly half of all 69 US data center projects scrapped since 2024. The surge in cancellations coincides with heightened market concerns over data center construction pace following Democratic gains in midterm elections.
