Maye Musk revealed that her son Elon Musk ignored her advice to focus on just a single business after selling PayPal, choosing instead to simultaneously launch SpaceX and Tesla. Speaking with Fox Business host Stuart Varney while promoting her memoir Timeless published by HarperCollins on September 15, the 78-year-old model provided insight into the multi-company strategy that built a fortune Forbes estimates at $929 billion.
Stock Holdings Drive Multibillion-Dollar Valuation
According to Maye Musk, the massive net worth reported by financial media does not represent liquid cash in a bank account. Forbes data confirms that Elon Musk owns approximately 38% of SpaceX and nearly 11% of Tesla, meaning his financial standing fluctuates directly with private and public equity valuations. The commentary follows reports that Musk became the world's first trillionaire on June 12 when SpaceX went public, amidst broader financial focus on SpaceX executive stock moves.
When her son asked after PayPal whether he should pursue electric vehicles, rocketry, or solar energy, Maye recalled advising him to pick just one due to his heavy workload. Instead, Musk launched multiple ventures at once, despite widespread expectations that they would fail.
AI Oversight and Personal Habits at Starbase
Maye Musk also discussed her regular use of Grok, the artificial intelligence chatbot developed by Musk's company xAI. Addressing whether artificial intelligence development should slow down, she referred to Musk's recent support for industry oversight, including his public agreement with Anthropic CEO Dario Amodei regarding competitive peer reviews—a topic gaining political momentum after recent White House discussions on AI governance.
Despite her son's status as the world's wealthiest individual, Maye noted that she sleeps on a small bed in his garage when visiting SpaceX's launch facility at Starbase, Texas, preferring it to a hotel suite located 45 minutes away. She added that she expects Musk to personally fly into space in the future.
Key Takeaways
- Maye Musk advised Elon Musk to focus on only one company post-PayPal, advice he rejected to form Tesla and SpaceX.
- Elon Musk holds roughly 38% of SpaceX and 11% of Tesla, anchoring his $929 billion net worth in equity rather than cash.
- Musk backs peer-review AI oversight for xAI and Grok alongside other industry leaders.
Why It Matters
Musk's refusal to diversify away from high-risk ventures illustrates how illiquid equity concentration drives modern billionaire wealth rankings. His simultaneous leadership across Tesla, SpaceX, and xAI gives him unprecedented influence across energy, aerospace, and artificial intelligence markets. As regulatory scrutiny around AI governance mounts, his overlapping control across these core technology sectors will remain a key focal point for institutional markets.
