As Elon Musk contemplates the relationship between several of his companies, he said on social media that Tesla shareholders will vote on whether to invest in xAI.

Tesla does not currently have any plans to acquire CEO Elon Musk's artificial intelligence startup xAI, but the electric vehicle maker could invest in the company, Musk said over the weekend.

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.
