Greece’s stock market becomes continental powerhouse as Euronext completes $6+ billion acquisition, positioning Athens as the Southeast Europe financing center

Greece‘s capital markets are experiencing unprecedented momentum as Euronext officially integrates the Athens Stock Exchange (ATHEX) into its pan-European platform. This landmark acquisition transforms Greece into a major hub for Southeast European investment. International investors are increasingly recognizing Greece as a compelling opportunity for 2026.

The Euronext Integration: A New Era for Greek Markets

The completion of Euronext’s acquisition of ATHEX on November 24, 2025, marks the most significant development in Greece’s financial history in recent decades. Euronext, Europe’s leading equities listing venue, now operates 1,800+ listed companies across its integrated network. This integration directly connects Greek issuers and investors to the continent’s most advanced trading infrastructure.

Shareholders of ATHEX approved the all-share exchange offer by overwhelming margins, reflecting strong confidence in the strategic partnership. The acquisition represents Euronext’s commitment to establishing Southeast Europe as a premier capital markets destination. Greece’s geographical position and emerging economic strength position it perfectly as the regional hub for pan-European funding.

Greek Markets Break Records, Attract Global Capital

Greece’s stock market outperformance is driving unprecedented international investor interest. The Athens Stock Exchange delivered +47.12% returns over eleven months through early December 2025, making it the world’s third-ranked exchange. Banking sector strength was particularly notable, with bank stocks gaining approximately 99% during the same period.

This exceptional performance reflects both Greece’s economic recovery and structural improvements in the investment environment. Greece’s debt-to-GDP ratio continues declining, and business confidence remains exceptionally strong. The country’s official upgrade to developed market status by major indices (effective September 1, 2026) will trigger automatic inclusion in major global portfolios.

Southeast Europe Emerges as Capital Markets Hub

Euronext’s strategic vision positions Athens as the primary financing center for the Southeast European region. Companies across the Balkans, Eastern Europe, and the Eastern Mediterranean now have direct access to Europe’s largest and most liquid capital markets. This geographic advantage transforms Greece from a peripheral market into a critical node in continental infrastructure.

Regional businesses seeking continental financing previously faced barriers accessing major European exchanges. The ATHEX integration eliminates these obstacles entirely. emerging markets in Southeast Europe can now list directly on Euronext’s regulated platforms, accessing institutional capital and funding programs previously unavailable. This structural change attracts companies contemplating relocation or expansion.

What Does This Integration Mean for Global Investors and the Greek Economy?

The Euronext-ATHEX integration fundamentally changes the investment proposition for Greece. Global asset managers operating within developed-market mandates will automatically gain exposure as Greece’s developed market status takes effect. Index funds tracking Europe will add Greek equities to their portfolios, creating immediate demand for shares across sectors.

International recognition translates directly into capital inflow. JP Morgan’s 16% return forecast for the MSCI Greece index in 2026 reflects expectations of continued economic growth and investor interest. The flow of €35.95 billion from European Recovery Funds will support infrastructure, digital transformation, and business expansion—creating future corporate profits and equity valuations.

For Greek companies small and medium-sized enterprises, the implications are equally significant. Access to Euronext’s capital markets expertise reduces the cost of raising equity funding. Direct visibility to continental investors improves growth financing options. Merger and acquisition activity is expected to accelerate as continental companies recognize the opportunity to acquire established Greek enterprises with emerging market growth profiles.
