Elon Musk’s net worth has reached an unprecedented $852 billion, and this makes him the first person in history to surpass the Elon Musk $800 billion milestone. The surge came after SpaceX acquired his artificial intelligence company xAI in a deal that was announced Monday evening, with Forbes estimating the transaction boosted his fortune by around $84 billion.

The merger values the combined entity at $1.25 trillion, with SpaceX accounting for $1 trillion and also xAI for $250 billion. At the time of writing, Musk holds an estimated 43% stake in the consolidated company, worth approximately $542 billion, and he also owns a 12% stake in Tesla valued at $178 billion, plus Tesla stock options worth another $124 billion.

Elon Musk Net Worth Today After SpaceX xAI Deal

The world’s richest person, Musk, has seen his wealth multiply through a series of strategic moves, and right now the Elon Musk SpaceX valuation stands at some pretty impressive numbers. Before Monday’s announcement, he owned roughly 42% of SpaceX, which a December tender offer valued at $336 billion when it priced the rocket maker at $800 billion. His 49% stake in xAI was worth $122 billion, following a funding round earlier this month that valued the AI firm at $250 billion.

Musk has now merged two of his controlled companies for the second time in under a year. Last March, xAI acquired social media platform X, formerly known as Twitter, in a deal that valued xAI at $80 billion and X at $33 billion—nearly matching what Musk paid for Twitter back in 2022, excluding debt.

SpaceX Valuation Reshapes Musk’s Empire

The Elon Musk SpaceX valuation now approaches Tesla’s market capitalization, which currently sits at about $1.58 trillion. SpaceX’s $1.25 trillion valuation is only 26% below Tesla’s, and this marks a significant shift in Musk’s portfolio composition. According to Forbes, SpaceX has become Musk’s most valuable asset by far.

SpaceX generated approximately $15 billion in revenue last year with $8 billion in profit, according to Reuters. The company leads the orbital launch services market through multi-billion dollar contracts with NASA and the Department of Defense, and it also operates Starlink satellite internet service with over 9,000 satellites in orbit and roughly 9 million customers.

Four Milestones in Four Months

The Elon Musk $800 billion milestone represents the fourth major wealth record that Musk has achieved since October. He became the first person worth $500 billion in October as Tesla’s stock climbed after he left President Trump’s Department of Government Efficiency. On December 15, Elon Musk’s net worth hit $600 billion when private investors valued SpaceX at $800 billion, up from $400 billion in August. Four days later, he crossed $700 billion after the Delaware Supreme Court restored his Tesla stock options, which had been voided by a lower court in 2024.

Elon Musk’s net worth today stands $578 billion ahead of the world’s second-wealthiest individual, Google cofounder Larry Page, who has an estimated net worth of $281 billion.

Tesla’s Declining Role and Regulatory Concerns

Tesla’s stock has dropped 6% so far in the Elon Musk net worth 2026 cycle. The electric vehicle maker reported a 16% year-over-year decline in vehicle deliveries in early January, and the company announced that total revenue fell 3% in 2025—the first annual decline on record. Last week, Musk told analysts that Tesla is ending production of its Model S and X vehicles, which made up less than 3% of annual deliveries in 2025.

The xAI acquisition brings new regulatory challenges that several analysts noted. Authorities in Europe, India, Malaysia, and California are investigating the AI company after its Grok image generator allowed users to create explicit deepfake images. On Tuesday, French investigators raided X’s offices and prosecutors ordered Musk to answer questions about suspected algorithm abuse.

Eric Talley, a law professor at Columbia University, noted that SpaceX investors may now have to shoulder some regulatory risks facing xAI.

“Different regulatory entities may say you have to be in good standing overall as an organization,” Talley said.

The Elon Musk net worth 2026 figures reflect both the opportunities and also the risks tied to his expanding empire. SpaceX is reportedly pursuing an IPO this year, which will subject the company to public market scrutiny. Musk’s role as both buyer and seller in these transactions has raised questions about the claimed valuations, though the upcoming IPO should provide market-based validation.

Strategic Vision Behind the Merger

Musk stated his vision for the merger in a blog post on SpaceX’s website:

“SpaceX has acquired xAI to form the most ambitious, vertically-integrated innovation engine on (and off) Earth, with AI, rockets, space-based internet, direct-to-mobile device communications and the world’s foremost real-time information and free speech platform.”

He also explained the reasoning behind the deal:

“Current advances in AI are dependent on large terrestrial data centers, which require immense amounts of power and cooling. Global electricity demand for AI simply cannot be met with terrestrial solutions, even in the near term, without imposing hardship on communities and the environment.”

Ali Javaheri, senior emerging spaces analyst at PitchBook, provided his perspective on the deal:

“It shifts the valuation story from a rocket company to a critical infrastructure plus platform business. The underappreciated angle is that connectivity, data, and compute are converging into a single stack where launch, global broadband, defense applications, and AI workloads reinforce each other.”

Michael Sobel, co-founder and president of Scenic Management, shared investor sentiment:

“It’s very much on investors’ minds. If it was a clean SpaceX IPO, everyone is super stoked. If it’s a multimerger combination of companies, they’re curious and eager and mostly trust [Musk], but they’re like ‘Hmmm.'”

Meanwhile, Moffett Nathanson analysts expressed some skepticism about the ambitious space data center plans:

“At a bare minimum, one can safely conclude that a full-fledged build is not happening anytime soon, given the requisite operational maturity, supply chain development, and financial requirements.”

Elon Musk’s net worth positions him as the world’s richest person by a considerable margin right now, and the merger between SpaceX and xAI has been described as the largest merger of all time at $1.25 trillion.
