MENA Newswire, NEW YORK: Elon Musk’s estimated net worth reached about $788 billion on Jan. 22, 2026, a record level on a widely followed real time wealth ranking after a rally in Tesla shares increased the value of his largest public stake. The estimate reflected end of day market prices and updated valuations used by the ranking, which tracks the paper value of founders’ holdings across public companies and private ventures.
Tesla shares rose about 4% on Jan. 22 after Musk posted on X that Tesla had begun operating some robotaxi rides in Austin, Texas, without a safety monitor in the vehicle. A video circulating online showed a passenger riding in a Tesla Model Y with no one in the driver’s seat and no chaperone in the cabin. The update added momentum to a stock that remains highly sensitive to announcements tied to autonomy and software.
Ashok Elluswamy, Tesla’s vice president of AI software, separately posted that robotaxi rides without safety monitors were publicly available in Austin, beginning with a limited number of unsupervised vehicles mixed into a broader fleet that still includes monitored rides. The posts described an initial rollout rather than a full scale commercial launch, and provided no public pricing or coverage map. The move followed earlier testing phases that included safety monitors.
Musk’s fortune is heavily concentrated in Tesla and typically moves by billions of dollars in a single session alongside the stock. Wealth rankings generally calculate the value of his Tesla stake using public market prices, while assigning modeled values to his holdings in privately held companies. The Jan. 22 estimate also reflected updated assumptions for private assets, which can be revised when companies disclose financing activity or comparable valuation data.
Robotaxi update drives market reaction
The Austin robotaxi change drew investor attention because it addressed a key question for Tesla’s autonomy program: whether the company would remove in vehicle safety oversight during passenger rides. Tesla has long sold and updated its driver assistance and full self driving software, and the company’s progress toward operating rides without a safety monitor has been closely tracked by customers, regulators, and investors. The announcement and confirmations helped drive the day’s move in Tesla shares.
Musk’s net worth estimates also incorporate his stakes in privately held businesses including SpaceX, xAI, X, Neuralink and The Boring Company. Unlike public stocks, private companies do not have continuously quoted prices, so valuations used in billionaire rankings are typically updated when firms report new funding rounds, disclose internal transactions, or when analysts revise estimates based on the latest available data.
On Jan. 6, 2026, xAI said it completed an upsized Series E funding round raising $20 billion, exceeding an earlier target of $15 billion. The company said the capital would support development of its AI models and expansion of computing infrastructure. Large private financings can materially affect Musk’s paper wealth because rankings often apply the most recent disclosed or inferred valuation to founders’ equity stakes.
Record wealth highlights volatility of estimates
The $788 billion figure represented one real time estimate, while other widely watched wealth trackers can show different totals because they use different methodologies for valuing private holdings, handling currency moves, and accounting for pledged shares or other financing arrangements. As a result, publicized net worth figures for the same individual can diverge, particularly when private company valuations are updated at different intervals.
Even with methodological differences, Musk’s wealth trajectory in late January 2026 underscored how tightly his net worth remains linked to Tesla’s market value. The Jan. 22 jump followed a single session gain in Tesla shares tied to the Austin robotaxi update, illustrating how quickly paper fortunes can shift with headline driven trading and how a limited operational change can translate into large moves for major shareholders.
