Musk now richer than any American — ever…

Billionaire entrepreneur Elon Musk has reportedly become the wealthiest American in history, with his net worth surpassing $1 trillion following gains in the value of his companies.

According to MarketWatch, the surge in shares of SpaceX and Tesla has pushed Musk’s fortune beyond the trillion-dollar threshold, making him the world’s first and only trillionaire.

The report, published on October 10, 2026, said Musk’s wealth exceeds the combined fortunes of the next three wealthiest individuals of his generation.

His financial standing also surpasses that of prominent American industrialists, including John D. Rockefeller, Andrew Carnegie, Cornelius Vanderbilt and John Jacob Astor.

MarketWatch explained that Musk’s historic position was established by comparing individual fortunes with the size of the United States economy during their respective eras.

The comparison highlights the extraordinary scale of Musk’s wealth relative to America’s economic output.

His growing fortune reflects the rising valuations of his business interests, particularly in aerospace and electric vehicles, strengthening his position atop global wealth rankings.
