Musk’s Wealth Hits $676B After $1.25T SpaceX-xAI Merger; Tesla Shares Down 5.45%
Elon Musk’s net worth climbed $57B to $676B in 2026 after the SpaceX-xAI merger valued at $1.25T, where he holds a 42% stake. Tesla shares are down 5.45% YTD even as a potential SpaceX IPO at over $1.5T and a near-$1T Tesla pay package could further inflate his wealth.
1. Wealth Milestone
Elon Musk’s net worth rose by $57B to $676B in 2026, propelled by gains from Tesla stock and the valuation of his SpaceX and xAI holdings. His wealth now exceeds the second-richest individual by over double.
2. SpaceX-xAI Merger Details
The merger assigned a $1.25T valuation to the combined SpaceX and xAI entity, where Musk’s 42% ownership translates into roughly $525B in equity. A potential IPO could lift the company’s market value above $1.5T.
3. Tesla Stock Performance and Pay Package
Tesla shares have declined 5.45% year-to-date in 2026, partially offsetting Musk’s wealth gains. A forthcoming pay package promising up to $1T in Tesla shares could further align his compensation with company stock performance.
4. Buffett Comparison
Musk’s net worth stands 453.7% above Warren Buffett’s $149B valuation, after Buffett’s wealth fell by $2.78B YTD due to philanthropic donations. This gap underscores the divergent wealth trajectories of the two executives.
