Millennium Management and Verition Fund Management, two significant multi-strategy hedge funds, are preparing to establish their initial operations in Greece, according to sources familiar with the matter. This move follows Rokos Capital Management's recent decision to relocate its founder, Chris Rokos, to Athens and open an office there. The funds are drawn by Greece's attractive tax regime for high-net-worth individuals, which allows qualifying foreign residents to pay a flat yearly tax of €100,000 on overseas income for up to 15 years.

This trend highlights Greece's success in attracting global financial talent and investment through its tax incentives, which contrast with the UK's recent changes to its non-domiciled tax regime. Chris Rokos, who was the UK's third-largest taxpayer in 2025 with an estimated bill of £330 million, is a prominent example of a billionaire choosing to move. His decision, first reported by Bloomberg, involves switching his residency to Greece and opening an Athens office.

The departure of such high-profile figures, including Rokos who has a net worth of about $4 billion, has raised concerns in the UK about the exodus of wealthy taxpayers. Analysts like Dan Neidle from Tax Policy Associates estimate that the UK could lose substantial tax revenue, potentially enough to fund 4,500 teachers, due to these moves. The UK government, however, maintains that it remains an attractive destination for talent and investment, citing its competitive and stable tax system.

Rokos's move also comes ahead of the UK Chancellor John Healey's first Budget on October 28, with ongoing discussions about potential tax increases. Rokos recently made a record £190 million donation to Cambridge University to establish the Rokos School of Government. The decisions by Millennium and Verition further solidify Greece's growing appeal as a hub for wealthy investors and financial professionals, posing a challenge to traditional financial centers.
