xAI raised $20 billion in its latest upsized funding round, exceeding the $15 billion targeted round size.
The financing will accelerate xAI’s infrastructure buildout, enable the rapid development and deployment of transformative AI products and fuel research.
Elon Musk’s artificial intelligence startup xAI had a year of breakthrough momentum in 2025, which included the expansion of its data centers—the world's largest AI supercomputers at Colossus I and II—and the launch of Grok 4, Grok Voice and Grok Imagine.
The S&C team advising xAI included Mike Ringler and Pete Jones.
