Which person is the richest in the world?

Musk’s fortune comes mainly from his stakes in Tesla and SpaceX, and in the mid-2020s estimates of his net worth have ranged into the hundreds of billions of dollars. Because billionaire wealth is mostly held in shares, rankings can shift within days. Jeff Bezos of Amazon, Bernard Arnault of luxury group LVMH and Larry Ellison of Oracle have all held or challenged the top position in recent years. Bill Gates topped the Forbes list for much of the 1990s and 2000s. Historians often name the 14th-century Malian ruler Mansa Musa as perhaps the richest person ever, though his wealth is impossible to measure precisely.
