If you're keeping score at home, Tesla Inc. (TSLA) CEO Elon Musk didn't just have a good year wealth-wise. He had a better year than two tech titans combined.
The Numbers Tell the Story
According to the Bloomberg Billionaires Index, Musk's net worth now sits at $638 billion after adding $205 billion in 2025 alone. That single-year gain is larger than the individual net worths of most billionaires on the planet.
For context, Alphabet Inc. (GOOG) (GOOGL) co-founder Larry Page saw his wealth grow by $101 billion this year, bringing his total to $270 billion. His fellow Google co-founder Sergey Brin added $92.5 billion to reach $251 billion. Combined, their gains hit $193.5 billion. That's impressive by any standard except one: it's still less than what Musk added by himself.
Billionaire Math Gets Wild
Zoom out further and the numbers get even more staggering. The world's top 10 richest people collectively added $604.39 billion to their net worth in 2025. To put that in perspective, that's more than Singapore's entire estimated nominal GDP of $574 billion for the year, according to International Monetary Fund figures.
Money Might Become Meaningless, Says Richest Man
Perhaps the most interesting part of Musk's wealth accumulation is his ongoing prediction that wealth itself might become irrelevant. The Tesla CEO has been increasingly vocal about artificial intelligence and robotics creating what he calls "universal wealth." His theory? These technologies will eventually eliminate scarcity altogether.
Earlier this month, Musk doubled down on this vision during a conversation with Indian entrepreneur Nikhil Kamath. He predicted that money could disappear "as a concept" once AI and robotics can satisfy all human needs. According to Musk, traditional jobs could become unnecessary as these technologies advance.
It's a bold philosophical stance from someone who just added more wealth in one year than most countries produce. Whether AI ushers in an era beyond money remains to be seen, but for now, the billionaire wealth tracker is alive and well.
