Amazon Web Services' campus in the Indiana Enterprise Center near New Carlisle is an $11 billion investment and one of the data center sites behind Project Rainier, the AI compute cluster that Anthropic uses to train and run Claude. AWS brought Project Rainier online in October 2025 with nearly 500,000 Trainium2 chips. St. Joseph County approved a tax abatement in 2024, and some county council members have since asked Amazon to voluntarily give back part of it.
