Chris Hohn

Sir Christopher Anthony Hohn KCMG (born October 1966) is a British billionaire hedge fund manager. As of 2026, he is worth £10.08 billion.

In 2003, Hohn established The Children's Investment Fund Management (TCI), a value-based hedge fund. Profits generated by the fund were initially proportionately allocated to The Children's Investment Fund Foundation, a registered charity in England and Wales.

He is known as an activist investor, and is an outspoken advocate of urgent action on climate change.

Early life Christopher Anthony Hohn was born on October 1966 in Addlestone, Surrey,

He was a pupil at St Paul's County Secondary School in Addlestone between 1979 and 1983, gaining 13 O Levels. He then attended the University of Southampton, and graduated in 1988 with first-class honours in accounting and business economics. He briefly worked for Coopers & Lybrand to help cover his impending student loan repayments. While at Southampton, a tutor advised him to apply for Harvard Business School, where he completed the Master of Business Administration course.

In 2019, it was reported that he had built a €730m stake in Heathrow Airport via a range of investment companies jointly taking a 4% stake in Spanish multinational Ferrovial.

In conjunction with TCI, Hohn launched the "Say on climate" initiative. The idea of the campaign is to make companies disclose their greenhouse gas emissions and their plans to manage these emissions and also give shareholders an advisory vote on the plans and their results. The initiative was first implemented by Aena, Unilever, Glencore, and CN but it has won many critics at the same time.

Investor activism In November 2022, Hohn, on behalf of TCI, wrote an open letter to Sundar Pichai, CEO of Alphabet and Google. In the letter, Hohn stated that Google's headcount was too high and should be reduced. On the same day, Hohn issued another letter to Pichai stating that there should be further job cuts with a target of 20%. His 2015 earnings of $250 million ranked him 12th among the 25 top earning hedge fund managers.

From March 2019 to March 2020 he paid himself $479 million, the highest annual amount paid to a person in the UK.

Donations As of 2019, Hohn's lifetime giving was listed at $4.5 billion by Forbes.

In 2019 it was reported by The Daily Telegraph that Hohn had donated £50,000 to environmental activist group Extinction Rebellion, with a further £150,000 donated by the Children's Investment Fund Foundation. None of the charity's money was spent on civil disobedience, it was claimed. Hohn is the single largest individual funder of Extinction Rebellion, a group that organises high-profile climate protests around the world, and whose U.S. affiliate has called for "rebellion against the U.S. government for its criminal inaction on the ecological crisis."

In April 2020, he made a £2.4 million donation to purchase around 100 SAMBA II machines to test for COVID-19.

In April 2025, in response to the Trump administration's cutoff of USAID funds, Hohn donated to MANA Nutrition, a company in Georgia, to enable continued production of peanut butter paste for malnourished children.

After a 2025 watchdog report indicated that between 2014 and 2023, Hohn had sent $553 million to U.S. political and environmental advocacy organisations, Hohn's foundation announced that it would stop giving money to U.S.-based groups, citing uncertainty about the U.S. policy environment governing foreign funding. Hohn has also been a major donor to the Arabella Advisors network via the New Venture Fund and Windward Fund.

Personal life In October 1995, he married Jamie Cooper, a fellow Harvard graduate student from Chicago, whom he had met at a party during his studies. Upon marriage, they took each other's surnames to become Cooper-Hohn, although he was still widely known as Hohn. The couple went on to have four children, including triplets. In 2013, it was reported that Hohn had begun divorce proceedings with his wife. In November 2014, he was set to pay his American-born ex-wife $500 million, in what was thought to be the biggest divorce settlement ever awarded by an English court. In December 2014, he was ordered to pay his ex-wife £337 million. His second wife is Kylie Hohn (née Richardson), who has a PhD from Harvard University and has taught at Harvard and the University of Cambridge. She is the CEO of LightEn.

Hohn was appointed Knight Commander of the Order of St Michael and St George (KCMG) in the 2014 Birthday Honours for services to philanthropy and international development.

Hohn practises yoga and does not eat meat.
