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

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

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.
