UNITED NEWS INTERNATIONAL (UNI) — You know that saying about the “rich getting richer”?

Well, one of the richer just became the richest person in history.

We’re talking about Amazon founder and CEO Jeff Bezos.

Amazon stocks have been surging, and Bezos has ridden the wave to the top of both the Bloomberg Billionaires Index and Forbes’ list of the world’s richest people.

On Jan. 8, both rankings put his net worth in the neighborhood of $105 billion.

That breaks the previous record held by Microsoft co-founder Bill Gates.

Gates’ current net worth is roughly $92 billion or $93 billion, depending on which index you’re using. But Bloomberg reports he would be worth over $150 billion had he not given so much of his fortune away.

Will Bezos ever top that? When you consider his ever-growing online retail empire, his ownership of The Washington Post and his foray into space travel via Blue Origin — the sky truly is the limit.
