While Tesla’s soaring stock is the main story, Elon Musk’s ascent to a $500 billion net worth is a testament to his Midas touch across multiple ventures. The tech magnate became the first person to reach this historic financial milestone on Wednesday, showcasing the combined power of his futuristic business portfolio.
At the heart of his fortune is his 12% stake in Tesla, the electric vehicle company now valued at over $1.5 trillion. The company’s stock has shrugged off a difficult start to the year to post a 13% gain in 2025, directly fueling the rapid expansion of Musk’s wealth. This was backed by strong fundamentals, including a record 497,099 vehicle deliveries last quarter.
However, a significant and growing portion of his wealth lies beyond Tesla. SpaceX, his private aerospace company, is a titan of industry, reportedly seeking a $400 billion valuation. Musk’s commanding 42% stake in the rocket firm makes up a substantial part of his net worth and solidifies his position as a leader in the commercialization of space.
His latest bet, on artificial intelligence with xAI, is already paying off handsomely. Data from Pitchbook reveals the company had achieved an impressive $75 billion valuation as of July. This illustrates investors’ unwavering faith in Musk’s ability to identify and dominate the next wave of technological innovation.
After temporarily topping $500 billion, his fortune stabilized at $499 billion. This event, driven by a synergy between his public and private enterprises, demonstrates a unique ability to build and scale multiple billion-dollar companies simultaneously, creating a level of wealth previously unseen.
