Elon Musk’s personal net worth of $681 billion now exceeds the combined fortune of the world’s ten richest billionaires in 2015, highlighting a seismic shift in global wealth concentration.
At a Glance
- The top 10 billionaires’ combined $559 billion in 2015 falls short of Musk’s current $681 billion
- Only five names from the 2016 elite list remain in today’s top 10
- The staying billionaires’ collective worth has more than doubled the entire 2016 rankings
- Why it matters: The chasm between the ultra-wealthy and everyone else has widened dramatically in under a decade
A decade ago, Bill Gates led the Bloomberg Billionaires Index with $84 billion. Today, Musk-who didn’t even crack the 2016 top 10-commands a fortune that eclipses the whole cohort from that year.

Musk’s AI Prediction
Beyond the numbers, Musk recently claimed on the Moonshots podcast that retirement savings will soon become irrelevant.
“You won’t need to save for retirement,” Musk said, predicting that artificial intelligence advancements will make traditional financial planning obsolete. “In the relatively near future, you could have whatever you want.”
He added: “It won’t matter to worry about, like, squirreling money away for retirement in 10 or 20 years.”
