Billionaire hedge fund founder Chris Rokos is reportedly preparing to move to Greece, according to several media reports, as he considers leaving the UK amid concerns about potential changes to the tax system. Rokos, who founded Rokos Capital Management, has an estimated net worth of around £2.6 billion and was ranked third in the Sunday Times Tax List 2026, having paid £330 million in taxes to the UK government last year. He is expected to be the first high-net-worth individual to leave the UK as new Chancellor John Healey prepares to announce his spending plan. Rokos is said to be arranging his residency in Greece and planning to open an office in Athens. Greece offers a special tax regime for high-net-worth individuals, which requires them to invest at least €500,000 in real estate, businesses, or shares in Greece within three years of applying. In return, they can pay a flat tax of €100,000 annually on income earned outside the country. This system is designed to attract wealthy individuals and encourage investment in the Greek economy. The move comes as the Labour Party, now in power, has introduced several policies targeting the super wealthy. These include closing tax loopholes for overseas trusts and increasing stamp duty for non-UK residents. These changes have already prompted some high-net-worth individuals to leave the country, such as steel magnate Lakshmi Mittal. In March, Rokos made headlines with a record £190 million donation to the University of Cambridge, aimed at funding the creation of the Rokos School of Government. This is said to be the largest single donation to a British university in modern history. Rokos, who attended a state primary school and later received a scholarship to Eton College and studied mathematics at Oxford, stated at the time that he "would like to give something back to Britain." Rokos's decision to move comes ahead of Chancellor John Healey's first Budget, scheduled for 28 October. In a recent BBC interview, Healey did not rule out raising taxes in the Budget, as the government faces pressure from rising borrowing costs. He declined to comment on specific tax decisions, stating he would focus on "balancing the books" and "controlling public spending." Other European countries, such as Italy, have also introduced tax incentives to attract wealthy foreigners, offering a flat tax of €300,000 on foreign-sourced income. A representative for Rokos was contacted for comment, but no response has been received yet.
