New research from digital reputation management company Five Blocks examined how eight AI engines describe 25 of America's largest AI data center projects, finding that none of the 1,200 general project descriptions rated were negative, but when the question changed to what challenges each project faced, 55% of answers were classified as negative. Google AI Mode produced negative answers to the challenges question 88% of the time, compared with just 6% for ChatGPT. For the first study, published Tuesday, Five Blocks asked eight AI engines two questions about 25 major U.S. data center projects every day throughout September 2026, using the prompts "Tell me about [project]" and "What challenges does [project] face?" More than 80% of challenge-related answers about Fermi America's Project Matador, Meta's Hyperion, Stargate and Vantage's Lighthouse were rated negative, while Amazon's Project Rainier and Microsoft's Fairwater project in Atlanta received negative responses roughly 20% of the time or less. Microsoft's Atlanta development had a negative-response rate of about one in five, while its Wisconsin project approached seven in ten. According to the study, Copilot's general description of the Fairwater Wisconsin project incorrectly claimed the project didn't exist until September 24.
