Former Microsoft CEO Steve Ballmer has surpassed his former boss, Bill Gates, on the Bloomberg Billionaires Index, becoming the sixth-richest person in the world with a net worth of $157.2 billion. Ballmer's wealth surged as Microsoft shares hit a new high, with over 90% of his fortune tied to the tech giant. In contrast, Gates has diversified his portfolio and donated billions to his foundation. Despite not signing the Giving Pledge like Gates, Ballmer and his wife focus on philanthropy through the Ballmer Group, aiming to enhance economic opportunities for families. Ballmer's rise in wealth highlights his successful tenure at Microsoft, where he worked for over three decades and served as CEO for nearly 14 years. His accomplishments exemplify the enduring legacy of Microsoft's leadership beyond Gates, now under CEO Satya Nadella.
