Posidonia, the world’s leading shipping exhibition, returns to Athens this week with its largest edition to date, bringing together more than 40,000 maritime professionals in an industry increasingly shaped by geopolitical risk, energy transition and security concerns.
Held from June 1 to June 5 at the Athens Metropolitan Expo, the 2026 edition is positioned as a record-breaking gathering both in scale and in strategic importance, as shipping sits at the centre of global debates over trade routes, sanctions and freedom of navigation.
The event will be officially opened by Melina Travlos, president of the Union of Greek Shipowners, alongside IMO Secretary-General Arsenio Dominguez, EU Transport Commissioner Apostolos Tzitzikostas and Greek Prime Minister Kyriakos Mitsotakis.
Organisers highlight that this year’s exhibition takes place in a climate of heightened geopolitical pressure, where maritime security, risk management and supply chain resilience have become core industry priorities.
“In a time of international challenges and multiple disruptions, Greek shipping stands as a pillar of stability, resilience and global connectivity,” Travlos said ahead of the opening.
Record participation and global reach
The scale of Posidonia 2026 underlines its growing influence in global maritime circles. More than 2,220 exhibitors from 83 countries and territories are participating, marking nearly 9% growth compared with 2024.
The exhibition spans 45,000 square metres and features a record 24 national pavilions, including the return of Germany and Italy with official delegations after a long absence.
This year’s show floor also reflects structural changes in the industry. More than 30 companies are presenting artificial intelligence solutions tailored to shipping operations, while over 100 exhibitors are focused on technologies designed to help shipowners meet tightening environmental regulations and net-zero targets.
Industry transformation at the centre of debate
Across the conference programme, digitalisation, cybersecurity, regulatory compliance and maritime decarbonisation dominate discussions, alongside increasing attention on alternative fuels and even emerging interest in nuclear propulsion as a long-term option.
Around 70 conferences and seminars are scheduled throughout Posidonia week, with several events hosted outside the main venue due to high demand.
The gathering comes at a time when shipowners are operating in one of the most complex environments in decades, with geopolitical tensions, sanctions regimes, shifting trade flows and instability in key maritime corridors reshaping operational decisions.
Posidonia managing director Theodore Vokos said recent disruptions in the Gulf had reinforced the sector’s resilience and global importance.
“The crisis highlighted the resilience of our shipping industry,” he said. “It demonstrated its importance to the global economy by continuing to operate and serve the world despite adverse conditions.”
Economic impact and strategic importance
Beyond the maritime sector itself, Posidonia 2026 is expected to generate more than €100m in economic activity for Greece, making it the most economically significant edition in the event’s history. Hotels, restaurants, transport providers and event services across Athens and Piraeus are all expected to benefit from the influx of international visitors.
The exhibition is organised under the auspices of the Greek Ministry of Maritime Affairs and Insular Policy, the Hellenic Chamber of Shipping and the Union of Greek Shipowners, reinforcing its status as the industry’s premier global meeting point.
As shipping’s political and economic significance continues to grow, this year’s Posidonia arrives at a moment where industry leaders, regulators and governments are converging in Athens to confront an increasingly uncertain global maritime landscape.
