From Space to Silicon: xAI’s ‘MACROHARD’ Roof Marker Signals Massive Datacenter Expansion in Tennessee” “Satellite images have revealed a bold message atop xAI’s Colossus 2 datacenter in Tennessee — the word ‘MACROHARD’ painted across the roof, a symbolic wink toward Microsoft that’s visible from space. Behind the humor is serious infrastructure. The Colossus 2 campus is rapidly scaling, with power and cooling systems expanding alongside construction. Reports indicate the site is moving toward ~400 MW of active capacity, with new gas turbines and cooling towers already being installed. Even more significant, xAI is building on a foundation that paves the way for over 2 GW of potential IT capacity in the future, backed by permitted infrastructure, ordered hardware, and on-site generation plans. The message from the rooftop may be playful — but the growth underneath it is anything but. #xAI #DataCenters #AIInfrastructure #TechnologyNews #ElonMusk #Tennessee #CloudComputing #BigTech
