Elon Musk’s rocket and satellite Internet company SpaceX plans to invest in his generative AI business xAI. The Wall Street Journal reports that SpaceX will pump $2 billion into the Grok company, as part of a broader $5bn round. SpaceX previously loaned money to Tesla and helped fund his acquisition of social media platform X.

The investment from SpaceX is part of xAI’s $5 billion equity fundraising effort, which was announced by Morgan Stanley last month.

Elon Musk clarified on social media that he does not support a merger between Tesla and his artificial intelligence company, xAI.
