Explanation

Elon Musk just became the richest person in the world, with a net worth of more than $185 billion. Thursday’s increase in Tesla’s share price pushed Musk past Jeff Bezos, who had been the richest person since 2017 and is currently worth about $184 billion. Musk’s wealth surge over the past year marks the fastest rise to the top of the rich list in history — and marks a dramatic financial turnaround for the famed entrepreneur.
