Billionaires' fortunes have more than doubled globally over the past decade, rising by 121% from $6,300 billion in 2015 to $14,000 billion in 2024, driven primarily by the technology sector, which saw its wealth triple to $2,400 billion. While the number of billionaires increased from 1,757 to 2,682, North American billionaires experienced consistent growth, reaching $6,100 billion by 2024. In contrast, real estate fortunes lagged due to market corrections and rising interest rates.
