Where Did Elon Musk's $5.7 Billion Mystery Donation Go?

Elon Musk gifted $5.7 billion worth of Tesla Inc. stock to charity in the span of 10 days in November -- many times more than he's given away through his eponymous foundation in the two decades since it was founded.

Elon Musk, it seems, is finally becoming a philanthropist on the scale of his billionaire peers.

The electric car and space mogul gifted $5.7 billion worth of Tesla Inc. stock to charity in the span of 10 days in November -- many times more than he's given away through his eponymous foundation in the two decades since it was founded. Where that donation is going is a mystery, but it's just one more signal that the world's richest person is taking philanthropy more seriously.

The decision by Musk, 50, to donate more than 5 million shares in the electric-car maker was disclosed in a regulatory filing Monday night, and comes on the heels of some of his biggest-ever philanthropic commitments -- though nothing has come close to the scale of billions of dollars. It would also help reduce what he called the biggest tax bill in U.S. history.

The Musk Foundation in the past couple of years has made eight-figure grants to the city and local school system near his South Texas spaceport, a $100 million ready-made competition to fight climate change and millions of dollars to a pair of Covid-19 researchers.
