Elon Musk and Bill Gates. Two entrepreneurs whose projects have changed the world forever and brought attention to global issues in our society. They are both business titans with a total state worth of over $300 billion.

Investors familiar with the matter told The Wall Street Journal that the rocket company SpaceX has agreed to invest a whopping $2 billion in xAI, the Musk-led firm behind the controversial large language model Grok. This investment makes up almost half of the $5 billion of equity that the AI company raised last month.
