Elon Musk Turns to Tesla and SpaceX to Fuel His AI Ambitions

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

The billionaire on Sunday said he plans to hold a vote by Tesla Inc. shareholders on whether the EV maker should invest in xAI, the cash-burning artificial intelligence startup he founded two years ago. That comes shortly after SpaceX, his mammoth rocket-launch company, agreed to invest about $2 billion into the AI firm, according to people familiar with the matter.

Musk said he didn’t support a merger of the companies but wanted Tesla investors to get exposure to the growth at xAI, which was valued at $113 billion after being folded into his social media platform, X, in an all-stock deal in March.

What the billionaire didn’t say was how all these additional investments from across his business empire would help stem the $1 billion-a-month that xAI is going through as it tries to build advanced AI models and take on competitors like Sam Altman’s OpenAI. Musk’s AI venture has yet to gain a foothold among big corporate clients or establish itself as central to developers as rivals OpenAI and Anthropic.

Musk’s xAI expects to burn through about $13 billion over the course of 2025, Bloomberg News has reported, meaning that its prolific fundraising efforts are just barely keeping pace with expenses.

Enter Elon Inc., the overlapping and ever-expanding constellation of businesses that could help extend the runway available to the cash-gobbling AI business.

The issue is, not every Tesla investor wants to tap the EV maker’s $1 trillion valuation to serve as Musk’s piggy bank. And xAI’s chatbot, known as Grok, comes with its own risks. On Friday, Grok’s account on X issued a lengthy apology for “the horrific behavior that many experienced” after it referred to itself as “MechaHitler” with posts that praised Adolf Hitler and appeared to call the Holocaust “effective.”
