Elon Musk is already the wealthiest individual in the world, with a net worth that surpasses the next richest person by hundreds of billions of dollars. The highly anticipated SpaceX/xAI IPO, which could come later this year, could give a further massive boost to the tech mogul’s fortune.
Elon Musk, Nearly A Trillionaire
With a current net worth of $666 billion, Musk could hypothetically buy up multiple automaker rivals of Tesla Inc. Alternatively, he could purchase every MLB, NBA, NFL, and NHL team. Estimates suggest that $426 billion of Musk’s wealth is due to his 44% stake in the recently merged SpaceX/xAI entity, which has assets across space exploration, social media, and artificial intelligence.
Valuation of SpaceX/xAI
The combined company was recently valued at $1.25 trillion, but more recent reports suggest that the SpaceX/xAI combination could be valued at $1.75 trillion with an IPO this year. This could translate to Musk’s stake being worth $770 billion, implying an increase of $344 billion from the last estimate. As a result, Musk’s wealth could increase above a trillion dollars, to $1.01 trillion, assuming valuations of other Musk-linked businesses, including Tesla, remain at current levels.
Musk’s Wealth History and Future
The Tesla CEO became the world’s richest person in January 2021, topping Amazon.com founder Jeff Bezos. Musk would hold the title for months, losing it several times to Bezos and LVMH CEO Bernard Arnault in 2022 and 2024. Musk has held the title fairly consistently over the last two years, briefly losing the title to Oracle co-founder Larry Ellison for one day in September 2025.
Sources of Musk’s Wealth
Estimates suggest that the majority of Musk’s wealth comes from his SpaceX/xAI stake, with an estimated 11% holding in Tesla currently worth around $167 billion. His stakes in other companies, such as The Boring Company and Neuralink, are worth billions of dollars as well.
Prediction of Musk’s Future Wealth
Without a SpaceX IPO, Musk could still continue to add to his net worth from rising valuations of his holdings in other businesses, and for meeting certain Tesla milestones that are part of a compensation package worth nearly $1 trillion. Tesla is currently valued at around $1.2 trillion. Prediction markets suggest that the prospect of Musk becoming the first ever trillionaire is a matter of when and not if.
