• Elon Musk's xAI announced a $6 billion Series C funding round on April 19, 2026, led by Sequoia Capital, valuing the startup at $24 billion post-money. • Funds will expand the Colossus supercomputer in Memphis, Tennessee, to 300,000 Nvidia GPUs for Grok AI training. • Investment accelerates US AI infrastructure race, countering China's advances and supporting domestic chip production.

Suit alleges the billionaire’s AI company is illegally spewing toxic pollutants from its datacenter in the Memphis areaA new lawsuit accuses Elon Musk’s artificial intelligence company of illegally spewing toxic pollutants into the Black neighborhoods on the border of Tennessee and Mississippi.The suit, filed Tuesday in Mississippi federal court, alleges xAI is violating the Clean Air Act due to emissions from its enormous datacenter in Southaven, Mississippi. The plaintiff – storied civil rights group the NAACP, represented by the Southern Environmental Law Center – says xAI has been polluting the surrounding historically Black communities by using dozens of methane gas generators without permits. The organization is seeking to force the company to stop operating its unpermitted turbines in Southaven. Continue reading...
