According to a Wall Street Journal report that cites investors close to SpaceX, the company has agreed to invest $2 billion in Musk’s AI startup xAI. The investment would reportedly be part of the $5 billion equity raise (along with another $5 billion in debt) that Morgan Stanley announced at the end of June.

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.

The money behind Elon Musk’s trillion-dollar empire is increasingly flowing in one direction: toward artificial intelligence.
