xAI escalates power infrastructure amid Clean Air Act lawsuit

Elon Musk's xAI is rapidly expanding Colossus 2's energy capacity—adding 19 gas turbines in two months—even as it faces legal challenges over emissions compliance. The expansion shows how compute-hungry AI companies are choosing aggressive infrastructure buildout over waiting for regulatory clarity, betting they can manage legal and reputational risk faster than competitors can scale. The lawsuit signals that neighbors and regulators are organizing opposition to data center proliferation, but xAI's acceleration suggests it's calculating the cost of litigation as lower than the cost of delayed training runs.
