Who Was the Richest Person in 2015
According to the most recent Forbes data, the richest person in 2015 was Bill Gates, the co-founder of Microsoft, with a net worth of approximately $79.2 billion at that time. Gates maintained the top spot on the Forbes Billionaires list for multiple consecutive years, driven by his stakes in Microsoft and his investment portfolio through Cascade Investment. His wealth was primarily derived from his significant shareholding in Microsoft, the software company he co-founded in 1975, which dominated the personal computing industry with products like Windows and Office.

Bill Gates' Business Empire and Wealth Sources
Microsoft and Early Career
Gates' wealth originated from his role as co-founder and CEO of Microsoft, where he led the company's strategy for decades. Microsoft's success with Windows operating systems and enterprise software created a massive revenue stream that funded his investment growth. He gradually reduced his day-to-day involvement at Microsoft after 2000 but retained significant shares, which appreciated as the company expanded into cloud computing with Azure. His stake in Microsoft remained the core of his fortune, with the company's market capitalization growth directly boosting his net worth over time.
Cascade Investment and Diversified Holdings
Beyond Microsoft, Gates managed a private investment firm called Cascade Investment, which held stakes in companies across energy, real estate, and consumer goods. Cascade Investment managed his diversified portfolio, including significant holdings in Canadian National Railway and Four Seasons Hotels. These investments provided steady returns and reduced reliance on Microsoft's stock performance alone. The firm's strategy focused on long-term value creation, with holdings in infrastructure and hospitality sectors contributing to his overall wealth stability.
Comparison with Other Billionaires in 2015

Gates' lead was attributed to Microsoft's global market dominance and his effective wealth management through Cascade Investment. The gap between the top three billionaires reflected the different scales of their business empires and stock market valuations at that time.
