Twenty years ago today, Bill Gates announced that he was stepping down as the CEO of Microsoft, which he founded with Paul Allen in 1975 and helped build into one of the top tech companies in the world. Now, he has a net worth of over $100 billion.
In 2017, it emerged Gates was donating 64 million Microsoft shares, worth about $4.6 billion, which reduced his stake to just over 1 percent. Since its launch, the 64-year-old has poured money into the philanthropic charity he runs with his wife, the Bill & Melinda Gates Foundation, which helps to eradicate disease and improve healthcare in developing nations.
On the rich list, he is second only to Amazon's Jeff Bezos. So, after distilling his Microsoft stake and donating billions to charity, it begs the question: how on earth is Gates maintaining that vast fortune?
To start, it helps that Microsoft has become a thriving company, with a share price that has quadrupled under the leadership of current CEO Satya Nadella, according to metrics from analysts at Statista.
And Gates' remaining 1 percent stake is still valued at a casual $7 billion, Business Insider reported.
