Elon Musk has reached a historic financial milestone, becoming the first person ever with an estimated net worth of $800 billion or more following a major merger between his aerospace company SpaceX and his artificial intelligence firm xAI. This landmark development significantly strengthens Musk’s position as the world’s richest individual.
According to Forbes and other financial trackers, the deal—announced in early February 2026—boosted Musk’s personal fortune by roughly $84 billion, bringing his total estimated net worth to about $852 billion. The combined company, formed by the acquisition of xAI by SpaceX, is valued at around $1.25 trillion, making it one of the most valuable private enterprises ever.
Before the merger, Musk held a significant stake in SpaceX (about 42%), which was valued at $800 billion, and a near 49% stake in xAI, valued at $250 billion. After consolidating the two companies, his combined ownership stake in the unified entity represents an extraordinary portion of his wealth.
SpaceX has now eclipsed all of Musk’s other major assets, including his roughly 12% stake in Tesla, which remains a major contributor to his fortune, along with valuable stock options.
This achievement marks the latest in a rapid set of wealth milestones for Musk over recent months. He previously became the first person worth $500 billion, $600 billion, and $700 billion—each record breaking earlier in late 2025.
The strategic merger not only reshapes Musk’s financial standing but also aligns his space and AI ventures, positioning the combined SpaceX‑xAI entity for future growth—including potential plans for space‑based AI data centers and an IPO later in 2026.
