Mark Coombs Net Worth

Mark Coombs has an estimated net worth of $2 billion, according to Forbes Real-Time Billionaires, Mark Coombs profile (figures as of October 20, 2026). That is down from a peak of $2.4 billion.

Mark Coombs is a British businessman and the chief executive of Ashmore Group, a London-based investment manager focused on emerging markets. Born in April 1960, he went to Dulwich College and studied law at St John's College, Cambridge. Forbes counts him as a self-made billionaire, having built his fortune from a business he started inside a bank.

His career began in 1983 in the Latin American department of Grindlays Bank, which later became part of the Australia and New Zealand Banking Group. In 1998 he started Ashmore as a new division of the bank. A year later he led a management buyout that made Ashmore independent, and in 2006 he took the company public on the stock market.

How Mark Coombs built his fortune

Coombs makes his money through his ownership of Ashmore. The firm invests in emerging markets, a field Coombs knew well from his early work on Latin America. Forbes reports that Ashmore manages some $57 billion in assets. Investment managers earn fees based on the assets they oversee, so the size of that pool and the firm's results drive the value of the company.

His stake is large. Forbes says Coombs owns around one-third of Ashmore's shares, and in 2007 he held 42.5% of the group. He has also grown the business through deals, including the purchase of the money manager Emerging Market Management. In 2019 he sold 10 million Ashmore shares, a move that brought in £43.5 million.

How his Forbes estimate has moved

Forbes estimated Coombs at $2.1 billion in 2019, then $1.7 billion in 2020. His figure jumped to $2.4 billion in 2021 before settling at $1.8 billion in 2022 and $1.8 billion again in 2023. Since most of his wealth is in Ashmore stock, his estimate rises and falls with the share price, which is closely linked to how investors feel about emerging markets.

Recent years have brought modest changes. Forbes put him at $1.9 billion in 2024 and $1.8 billion in 2025. On its 2026 World's Billionaires List, his estimate climbed to $2.1 billion. As of October 20, 2026, the Forbes real-time billionaires tracker showed $2 billion. That keeps him close to where he started in 2019, despite the share sale that year. Coombs lives in Wimbledon, London, with his wife Rebecca, and he continues to lead the firm he founded.
