Star hedge fund manager Chris Rokos is relocating from Britain to Greece, despite having just spent more than 200 million pounds rebuilding Tottenham House in Wiltshire and donating 190 million to Cambridge University. His move joins a broader billionaire exodus that includes Lakshmi Mittal and Nassef Sawiris after the non-dom tax status was abolished.

Bloomberg reported in September that Rokos was preparing to leave the UK and switch his tax residency to Greece after Britain scrapped its non-dom regime in April 2025, making income earned abroad liable for tax. Greece's non-dom regime offers a flat tax of €100,000 on all foreign income for up to 15 years, for individuals who invest at least €500,000 in the country within three years of applying. Rokos Capital Management is expected to open an office in Athens as part of the move.

The paradox is Tottenham House: a Grade I-listed, 200-room Palladian mansion near Marlborough in Wiltshire that Rokos has spent eight years restoring at a cost of more than £200 million, employing hundreds of local craftsmen, with plans for a tennis pavilion, a private cinema and tracts of surrounding countryside to rebuild the estate. "Who spends more than £200 million on a new home and then moves to another country?" the Times asked. Well-placed sources say Rokos will complete the project — but that his departure is not an exercise in acrobatic accountancy: he is moving his whole life and his business.

Rokos, 55, ranked third on the Sunday Times' annual list of Britain's biggest taxpayers, paying an estimated £330 million in tax in 2025, and has an estimated net worth of around $4 billion. In April he donated £190 million to Cambridge University — the largest gift in its history — to establish the Rokos School of Government. The publicity-shy businessman, who grew up in Hammersmith and attended Eton on a scholarship after a state primary school, has also funded scholarships at his alma mater, a fellowship at the London Institute of Cancer Research and orthopaedic research at Imperial College. A co-founder of Brevan Howard who left in 2012, he founded Rokos Capital Management in 2015 and is a father of five.

His exit has sharpened the political row ahead of the Budget. Shadow chancellor Andrew Griffith told parliament that, on the Treasury's own statistics, replacing Rokos's tax would take 38,000 average-income taxpayers, arguing that "every time a billionaire leaves, our country becomes poorer." Chancellor John Healey responded that the Budget would give families and businesses "a bit of breathing space." Rokos's move follows the reported departures of the steel tycoon Lakshmi Mittal, Egypt's richest man Nassef Sawiris and Goldman Sachs vice-chair Richard Gnodde. Rokos has declined to comment on his exit.
