The merger of SpaceX and xAI has reshaped the global tech landscape and sharply lifted Elon Musk’s personal wealth, pushing his estimated net worth to $852.5 billion, according to real-time tracking by Forbes.

The deal, announced on February 3, values the combined SpaceX–xAI entity at $1.25 trillion, making it the most valuable private technology company ever created. Musk owns roughly 43% of the merged group, a stake valued at about $542 billion, forming the largest component of his fortune.

Beyond the merger, Musk’s wealth is also supported by his holdings in Tesla, estimated at $178 billion, along with approximately $124 billion in stock options tied to future performance. Taken together, Forbes describes the increase as the largest single jump in net worth ever recorded.

The surge places Musk ahead of fellow technology billionaires Larry Page, Sergey Brin, and Jeff Bezos combined, whose collective net worth stands at roughly $783.5 billion, underscoring the unprecedented scale of the valuation created by the merger.

Market analysts say the SpaceX–xAI combination reflects a broader shift in the technology sector, where artificial intelligence is being fused with capital-intensive infrastructure such as satellites, launch systems, and large-scale computing. Supporters argue the structure could accelerate the development of advanced AI systems, while critics have questioned whether the valuation can be sustained without a public listing.

Speculation has intensified over whether Musk could become the world’s first trillionaire, with some investors pointing to a potential SpaceX initial public offering and rapid advances in AI as possible catalysts. Others remain sceptical, cautioning that regulatory scrutiny, execution risks, and market conditions could temper further gains.

For now, the SpaceX–xAI merger has not only redefined the upper limits of private company valuations but has also reset benchmarks for personal wealth in the modern technology era.
