He has become a player in esports, investing with his son, Gregory, in Immortals Gaming Club, which acquired Infinite Esports in 2019 in the industry’s first $100 million deal. He has also made investments in private equity, hedge funds, venture capital and asset management firms. Milken has deep ties to Santa Monica-based Stone Canyon Industries Holdings Inc., which has been active buying industrial packaging and container makers. Much of Milken’s net worth stems from his early investment in Kite Pharma, a biotech firm acquired by Gilead Sciences for $12 billion in 2017. Milken’s Knowledge Universe, an early childhood education business, sold its Knowledge Schools subsidiary in 2015 for $1.3 billion while retaining its real estate holdings. THE BUZZ: Milken threw himself and the Milken Institute into the fight against Covid-19, working the phones 17 hours a day to facilitate medical research and the public health response among leaders from the business, academia, government and nonprofit sectors. In his new podcast series, “Responding to Covid-19: Conversations with Mike Milken,” the former financier interviews individuals at the forefront of the pandemic. Milken, who served a prison sentence for securities fraud in the 1980s, was pardoned by President Donald Trump in February. The Milken Institute’s new Center for Advancing the American Dream in Washington, D.C., promotes equal access to education, job training and health care while also aiming to foster entrepreneurialism and innovation.
