Who are the world's wealthiest atheists?

I’m asking about self-proclaimed atheists that are public about their lack of belief in god.

My theory is that most people who claim to believe in god have a “just in case” mentality, either consciously or subconsciously. Thus, the very wealthy or very poor tend to be more religious. The wealthy have something to protect so they “believe” just in case there is a god who can take everything away. The poor “believe” just in case a god exists, who may pull them out of poverty.

Based on this Wikipedia list, I’ll suggest Mark Zuckerberg, whose Facebook stock is worth about $16 billion. Any atheists richer than that?

“Zuckerberg was born in 1984 in White Plains, New York. He is the son of Karen (née Kempner), a psychiatrist, and Edward Zuckerberg, a dentist. He and his three sisters, Randi, Donna, and Arielle, were brought up in Dobbs Ferry, New York. Zuckerberg was raised Jewish, had his bar mitzvah when he turned and has since described himself as an atheist.”

ETA: Too slow!

Looks like George Soros is worth $22 billion.

Per this Wikipedia reference, both Bill Gates and Warren Buffett are agnostics. Does that count?

I think self-proclaimed agnostics would count for this discussion.

As I always say (or sometimes say, anyway);

“If you want to know what God thinks of Money, just look at who he gives it to.”
