Transatlantic Investment Group Announces €50 Billion AI Data Center and Innovation Campus in Croatia — the Largest Investment in Croatian History and Among the Largest Private U.S. Investments in Europe
DUBROVNIK, Croatia--( BUSINESS WIRE)--Pantheon Atlas LLC, a transatlantic-led investment group, today announced the development of Pantheon AI, a hyperscale AI data center and innovation campus in Topusko, Croatia, designed in accordance with NVIDIA GW-Scale AI factory standards, that will bring more than €50 billion in total investment to the central European nation and establish it as a leading regional hub for digital infrastructure.
Pantheon AI solves a structural capacity gap in Europe — where surging AI-driven demand for data center capacity has outpaced available power, land, and construction resources — delivering the highest levels of availability (above Tier IV), a one-of-a-kind standard in Europe. The transatlantic partnership developing the campus combines American capital and investment expertise with extensive technical knowledge, local relationships, regulatory groundwork, and significant and unique grid access built over years of work in Croatia.
The project will enable integration of up to 5.2 GW of renewable energy onto Croatia’s grid and represents the largest investment in Croatian history and among the largest private U.S. investments in Europe. The announcement was made at the Three Seas Initiative Summit in Dubrovnik among 13 presidents and prime ministers as well as Chris Wright, United States Secretary of Energy.
"Pantheon AI is a signal to the world that Croatia is open for the highest-caliber investment,” said Jako Andabak, Founding Partner at PantheonAI. "This project is the culmination of years of work to bring world-class digital infrastructure to Croatia, and we have assembled the deep local expertise, grid relationships, and regulatory groundwork required to meet demand for data center capacity.”
Europe's established data center hubs are operating below 8% vacancy, with significant grid connection delays compounding the pressure. Central and Eastern Europe, where data center electricity demand is projected to grow three to four times by 2035, does not have a gigawatt-scale, AI-optimized facility to serve that requirement. EU data sovereignty regulation is simultaneously compelling major technology companies to store European data within EU borders.
"We have assembled a transatlantic partnership to solve one of the most pressing challenges in global digital infrastructure: enabling hyperscale operators to meet AI-driven demand at scale,” said Ryan Rich, Managing Partner of PantheonAI. “We have lined up the power, fiber, regulatory stability, and institutional support to solve that problem in Europe, and we will establish Croatia and Central Europe as a premier destination for world-class digital infrastructure."
"The race to lead in artificial intelligence is global, and we are pleased to see American capital and investment expertise like Pantheon AI anchoring that leadership in allied, democratic nations,” said Joshua Volz, Special Envoy for Global Energy Integration, U.S. Department of Energy. “Critical infrastructure of this scale, built by the private sector responding to real market demand, is exactly how US interests and European security advance together.”
Construction of the €12 billion campus begins early 2027 and it will be fully operational by the first quarter of 2029. Total investment will exceed €50 billion as hyperscale tenants deploy equipment and technology at scale.
