SpaceXAI is expanding its Colossus 2 data center with two new campuses in Southaven, Mississippi, adding around 420,000 Nvidia GB300 GPUs focused on AI training and inference workloads, aiming for operation by the end of 2026. The project faces regulatory challenges including environmental permits and lawsuits linked to gas-fired power plant emissions and turbine permits.
This Wire brief sits within Fusion42's coverage of AI Infrastructure.
◆ ◆ The Wire takeaway
Your AI capacity just grew by hundreds of thousands of GPUs in Mississippi; this opens a door to rent compute at scale but also flags regulatory delays. You need to factor in environmental and legal risks as much as infrastructure readiness for timely operations and customer delivery.
