Warren Buffett could've been worth $102 billion

Warren Buffett is now the world's third-richest person.

But he could be even richer.

On Tuesday, Bloomberg News reported that Buffett was recently passed by Amancio Ortega, the Spanish fashion magnate, as the world's second-richest person.

Buffett's net worth currently stands at $70.2 billion, but according to Bloomberg, without his philanthropic giving Buffett's net worth would be $102 billion.

This would've made him the richest person in the world.

According to the Bloomberg Billionaires Index, Bill Gates, a board member at Buffett's Berkshire Hathaway, is the world's richest person with a net worth of around $86 billion.

Ortega's net worth currently stands at $71.5 billion.

Both Buffett and Gates have signed the Giving Pledge, a pledge to give away at least half of their wealth to philanthropy or charity during their life or through their will.
