In a surprising turn of events, Elon Musk's xAI has secured a substantial $430 million investment from Tesla in 2025, marking a significant milestone in the tech industry. This deal involves Tesla's cutting-edge Megapack backup batteries, which are designed to provide reliable power solutions. The Megapack's versatility is evident in its application to xAI's data infrastructure in Memphis, Tennessee, where it powers the Colossus data center. However, this partnership has sparked controversy, as xAI's operations at the facility have faced scrutiny due to the use of natural gas-burning turbines, leading to community complaints and environmental concerns.
