Elon Musk's net worth is $850 billion, making him the richest person who has ever lived, adjusted for everything.

“As of early 2026, Elon Musk's net worth is estimated to be around $850 billion by sources like Forbes, making the first part of the claim accurate for the time the video was produced. However, the assertion that this makes him the richest person who has ever lived is debatable. When adjusted for inflation and share of the economy, historical figures like John D. Rockefeller are estimated to have had fortunes equivalent to hundreds of billions, and rulers like Mansa Musa of the Mali Empire are often cited as having wealth that is considered incomprehensible and possibly far greater. Context: While Musk's wealth is record-breaking by modern standards, historical comparisons are complex. The wealth of historical figures is often measured as a percentage of their society's total economic output, which can result in inflation-adjusted figures that rival or exceed modern fortunes.”
