Confidence rating:

The majority of Grayken's fortune is derived from his control of closely held Lone Star Funds, a private equity firm that invests in distressed debt. He's credited with all of the company based on US Securities and Exchange Commission filings that identify him as the sole shareholder.

The firm has raised more than $85 billion from investors since it began in 1995 and has bought assets with an aggregate price of more than $250 billion, according to the company's website. The value of assets under management isn't disclosed. It's calculated to be about $77 billion based on capital raised at funds that remain active, according to Dec. 31, 2021 data on the company's website.

Lone Star is valued using the average price-to-assets under management multiple of five publicly traded peer companies: Apollo, Ares, Blackstone, Carlyle Group and TPG.

Grayken personally invested $680 million into two Lone Star Funds, according to the minutes of meetings with two of the funds' institutional investors. The investments form the basis of his cash holdings.

Hudson Advisors, an affiliate asset-management company owned by Grayken, is valued as part of Lone Star.

He also owns properties in the UK, Switzerland and the US. They're valued according to reports in the Irish Independent and Boston Globe.

Joseph Sala, a spokesman for Lone Star at New York-based Joele Frank Wilkinson Brimmer Katcher PR, said Grayken declined to comment on his net worth.


Family: Married, No children

John Grayken was born in Boston in 1956. He graduated from the University of Pennsylvania with a bachelor's degree in economics followed by an MBA from Harvard Business School.

He started his professional career in Morgan Stanley's real estate group, moving on to work for Texas billionaire Robert Bass, whose firm partnered with the Federal Deposit Insurance Corp. following the savings and loans crisis. Grayken ran the partnership and helped manage distressed assets.

In 1995, Grayken started his own fund, Lone Star, to buy distressed assets. He raised $396 million for Brazos, his first fund. Since then, he's invested in commercial and residential real estate as well as consumer debt products and financial services companies.

Lone Star fought a four-year legal battle with South Korean prosecutors after Lone Star's top executive there was convicted in 2008 of illegally manipulating the stock price of Korea Exchange Bank in order to acquire it at a lower price in 2003. The conviction was overturned in June 2008 and the bank was sold four years later.

Grayken renounced his U.S. citizenship in 1999 and became a citizen of Ireland.
