Millennium Management plans first office in Athens, Greece

Millennium Management, one of the world’s largest multi-strategy hedge funds, is setting up shop in Athens. The firm incorporated Millennium Capital Management (Greece) in July 2026 with an initial share capital of €100,000, making it the latest heavyweight to plant a flag in a city that is quickly becoming finance’s favorite Mediterranean outpost.

The new entity is 99% owned by Millennium’s New York-based parent company and operates under Martin Pabari, the firm’s EMEA chief executive based in London. For a fund managing roughly $92 billion in assets, a €100,000 incorporation fee is basically a rounding error.

Athens is having a moment

Millennium’s move comes on the heels of news that Chris Rokos, founder of Rokos Capital Management and one of London’s most prominent macro traders, plans to relocate his personal residency to Greece and open an office there in September 2026. When two of the hedge fund industry’s biggest names pick the same city within months of each other, it stops looking like coincidence and starts looking like a trend.

The magnet pulling them south is, predictably, taxes. Greece offers a flat €100,000 annual tax on foreign income for qualifying residents, a deal that lasts up to 15 years. For billionaire fund managers generating enormous returns from global markets, that fixed-rate arrangement is extraordinarily attractive compared to the UK’s evolving tax landscape.

Rokos’s departure from Britain was explicitly linked to changes in UK tax policy. Greece, which spent years as a cautionary tale about sovereign debt and economic mismanagement, has quietly rebuilt itself into something resembling a tax-friendly haven for the ultra-wealthy.

Millennium, for its part, isn’t exactly a newcomer to the Greek market. The firm has maintained trading activities in Greek equities for at least five years, so the incorporation formalizes a relationship that already existed.

Why hedge funds are rethinking London

The broader context here is a slow but steady reassessment of London’s dominance as Europe’s financial capital. Brexit reshaped the regulatory relationship with the European Union. Rising operational costs made London increasingly expensive. And evolving UK tax policies, particularly around non-domicile status, have made the arithmetic less favorable for internationally mobile fund managers.

Greece has positioned itself to capture some of that migration. The country’s flat-tax regime for foreign income is the headline perk, but it also offers a lower cost of living compared to London and improving infrastructure for professional services.

What this means for markets and investors

For Greek equities and the local financial sector, the arrival of firms like Millennium should boost market liquidity. A $92 billion fund with a formal local presence is likely to deepen its engagement with Greek-listed companies and increase trading volumes on a relatively small exchange.

The risk, of course, is political. Greece’s favorable tax regime exists because the current government chose to create it. Future administrations could modify or eliminate the flat-tax arrangement, which would undermine the primary incentive drawing these firms. Fund managers relocating to Athens are essentially making a bet that Greek tax policy remains stable for the better part of two decades.
