How billionaire investor Ken Griffin makes and spends his money: he stopped donating to Harvard, but he’s splurged on beachfront mega-mansions, Covid-19 relief efforts … and the Republican Party

  • Griffin is among the world’s biggest private supporters of charities and non-profit organisations, having donated over US$2 billion to philanthropic projects
  • He splurged around US$500 million on two paintings, and bought America’s most expensive house, a four-floor penthouse in Manhattan, for US$238 million

He may have reportedly given over US$500 million to Harvard and US$2 billion in charitable donations overall, but billionaire Kenneth Cordele Griffin recently made headlines for halting his funding to the prestigious university over its handling of alleged antisemitism on campus. The move has brought his wealth sharply into focus.

Griffin made his US$37 billion fortune through business and spends much of it on philanthropy, educational donations, record-breaking properties, super expensive art and private jets, per Forbes.

While Harvard deals with the fallout of his decision, here is a closer look at Griffin and how he makes (and spends) his billions.

Harvard played a big part in Griffin’s financial journey. It was at the university that he first started investing, according to his biography in the Milken Institute. He installed a satellite dish in his dorm room in 1987 to get real-time stock information. He began investing with US$265,000 in capital, according to Bloomberg. Three years later, he started his own investment firm, Citadel, with US$4.2 million of investor money, reported Business Insider.

Reflecting on the events leading to this, Griffin told Bloomberg that the crash of 1987 led to him becoming a “boy genius”. “I knew I was boy lucky, because I was shorting the market intentionally, but outside investors went, ‘This person is a genius, he made money in the crash’ … it gave me a track record early on that was attractive to investors,” he recalled.

Citadel Securities, a separate market making firm also founded by Ken Griffin, has become a global leader in the field, serving over 1,600 clients including many of the world’s largest sovereign wealth funds and central banks. Forbes reports that Citadel manages more than US$60 billion in assets.

The firm has made him the world’s most successful hedge fund manager in terms of earnings, per Reuters, with Bloomberg estimating he may have around US$9 billion in personal assets in the company’s funds.

In 2018, he was the richest man in Illinois with a fortune of US$9 billion, per Forbes, and his worth has grown every year since. By 2023, he was the 22nd richest man in the US with US$35.4 billion, per the same publication. By January, his bank balance stood at US$37.2 billion.

He’s big on philanthropy, donating US$2 billion so far
