MARKET SYNOPSIS

The Ireland submarine cable landing station real estate market size was USD 412.8 Million in 2025 and is expected to register a revenue CAGR of 13.6% during the forecast period, reaching USD 1.54 Billion by 2035. Market revenue growth is supported by Ireland's structural position as the European Union's dominant transatlantic submarine cable gateway, anchored by a combination of geographic proximity to the North American Atlantic coast reducing cable length and therefore transmission latency relative to continental European landing points and the deepest concentration of hyperscaler data centre infrastructure in the EU, with Amazon Web Services having invested approximately USD 11.9 billion in Ireland since 2012 and operating or planning at least 15 data centres across Dublin, Clonshaugh, and Blanchardstown per CSIS analysis of September 2025. The country's cable landing real estate market encompasses the landing station buildings, civil beach access works, armoured cable burial routes, repeater huts, and network operations centres at each cable terminus, as well as the adjacent colocation data centre real estate that connects landing station infrastructure to national and European terrestrial fibre networks. Ireland's active and planned submarine cable systems landing as of Q2 2026 include AEC-1, AEC-2/Havfrue, AEC-3/Amitie, EXA Express, CeltixConnect-1, CeltixConnect-2, IRIS, PISCES, the Beaufort Ireland-UK cable, and the Fastnet AWS private cable with a 2028 operational date. For instance, in November 2025, Taoiseach Micheal Martin of Ireland welcomed the announcement of the Amazon Fastnet transatlantic cable, stating that the cable will help Ireland become a true gateway to Europe for submarine telecommunications cables and that the investment will enhance global connectivity and reinforce Ireland's status as a leading digital hub per verified Irish Government and Amazon press releases of November 2025. These are some of the key factors driving revenue growth of the market.

EXA Infrastructure, United Kingdom, completed its acquisition of Aqua Comms, Ireland, for approximately USD 59 million in December 2025 per RCR Wireless reporting of January 2026, consolidating control of the AEC-1 landing at Killala, County Mayo a direct 5,534 kilometre link connecting Shirley, New York, to Ireland the AEC-2/Havfrue landing at Leckanvy, County Mayo, and the CeltixConnect-1 and CeltixConnect-2 systems landing in the Dublin area, creating EXA as the dominant cable system operator and landing station real estate holder on Ireland's Atlantic west coast. Microsoft Corporation, United States, filed regulatory applications for three Ireland-UK subsea cables in January 2025, with each new cable system generating landing station real estate requirements at Irish termini in addition to Microsoft's existing co-ownership and capacity positions on AEC-1, Amitie, EXA Express, Marea, and SeaMeWe-6 per TeleGeography data and Data Center Dynamics reporting. The Havfrue/AEC-2 cable, co-owned by Aqua Comms (now EXA), Meta Platforms, Google, and Bulk Infrastructure, delivers 108 Tbps of design capacity from New Jersey via its Irish landing at Old Head Beach, Leckanvy, with the multi-owner structure reflecting the industry's transition from single-operator to consortium and, increasingly, hyperscaler co-ownership models for trans-Atlantic cable systems. The Celtic Interconnector, a power transmission subsea cable connecting Ireland to France at 575 kilometres, began cable-laying operations off Ireland's southeast coast in 2023 with over EUR 530 million in EU grants and EU Project of Common Interest status per Submarine Networks reporting, adding a distinct power interconnection landing station real estate category to Ireland's subsea cable portfolio. These are some of the key factors driving revenue growth of the market.

However, the Ireland submarine cable landing station real estate market faces structural constraints that temper the pace of expansion and the geographic distribution of new cable investment. Planning and environmental permitting timelines for cable landing stations in Ireland's coastal marine environment are extending, with Amazon's Fastnet station at Owenahincha requiring Cork County Council approval with conditions covering environmental monitoring, hydrocarbon interceptors, and water quality management before construction could commence per Irish Examiner reporting of April 2026. Ireland's submarine cable infrastructure faces documented geopolitical security risks, with the Russian vessel Yantar patrolling above subsea cables in the Irish Sea and deploying drones in November 2024 requiring Irish Defence Forces escorts and with the CSIS analysis of September 2025 documenting Russian mapping of cable landing stations and geopolitical actor endorsement of cable infrastructure attacks as legitimate military objectives. The concentration of cable landing stations on Ireland's west coast around Mayo and Galway creates resilience vulnerability, as a single disruptive event in a geographically constrained coastal corridor could affect multiple cable systems simultaneously. Iran-US geopolitical tensions and LNG price volatility through the Strait of Hormuz, as confirmed by IMF March 2026 analysis, create upward pressure on Irish electricity prices given Ireland's dependence on gas-fired generation, increasing the continuous power costs of landing station repeater power feeding and network operations infrastructure. These factors substantially limit Ireland submarine cable landing station real estate market growth over the forecast period.

Five Coastal Landing Zones Defining Ireland's Cable Real Estate Geography

County Mayo hosts the largest concentration of transatlantic submarine cable landings in Ireland, anchored by EXA Infrastructure's (formerly Aqua Comms) landing positions at Leckanvy and Killala that together terminate the AEC-1 and AEC-2/Havfrue cable systems providing direct links to New York and the broader North American eastern seaboard. The AEC-1 cable, launched in 2016 and spanning 5,534 kilometres between Shirley, New York and Killala, County Mayo, is operated by EXA following its acquisition of Aqua Comms in December 2025 and provides high-capacity, low-latency transatlantic connectivity that serves as the backbone of Ireland's direct US-to-Ireland broadband capacity. The AEC-2/Havfrue cable lands at Old Head Beach, Leckanvy, delivering 108 Tbps of design capacity as a trans-North Atlantic system co-owned by EXA, Meta Platforms, Google, and Bulk Infrastructure, with the Mayo landing point serving as the Irish terminus for traffic routed across the entire Havfrue system to New Jersey and onward to Denmark and Norway. The geographic clustering of multiple cable systems within a 20-kilometre coastal radius at the Killala-Leckanvy corridor creates a cable landing zone resilience concern that is being monitored by Irish Defence Forces following the Yantar surveillance incidents of 2024.

County Cork is Ireland's fastest-growing submarine cable landing zone, with Amazon Web Services receiving Cork County Council planning approval on April 20, 2026 for its Fastnet cable landing station at Owenahincha, serving as the European terminus of the Fastnet transatlantic system linking Maryland to Cork with 320 Tbps capacity. Taoiseach Micheal Martin stated in November 2025 that the Fastnet cable will help Ireland become a true gateway to Europe for submarine telecommunications cables and will enhance the country's global connectivity per verified Irish Government press releases. The Fastnet system incorporates optical switching branching unit technology enabling future route diversity, is designed specifically to handle growing AI traffic loads with armoured nearshore cable protection against natural and human threats, and will integrate directly into AWS's global network infrastructure spanning 38 geographic regions and 120 availability zones connected by over nine million kilometres of terrestrial and subsea fibre per AWS company disclosure. Cork's only existing major transatlantic cable prior to Fastnet is the EXA Express (formerly Hibernia Express), which lands at the Hollyhill Industrial Estate in Cork at 53 Tbps capacity approximately one-sixth the capacity of the forthcoming Fastnet system confirming that the Fastnet landing will transform Cork from a secondary into a primary Irish cable landing zone by capacity within a single cable deployment cycle.

County Dublin and the Irish east coast host the primary carrier-neutral cable landing station in Ireland EXA Infrastructure's facility in Clonshaugh Business Park, Dublin which is co-located with five Amazon Web Services data centres and serves as the terrestrial interface for CeltixConnect-1, CeltixConnect-2, the EXA Atlantic cable, and other short-distance Ireland-UK systems that provide onward routing for traffic arriving at Ireland's west coast Atlantic landing stations. The Clonshaugh co-location of EXA's landing station and Amazon's data centre infrastructure is the model that Amazon is now replicating at scale with its privately-owned Fastnet station in Cork, providing direct landing-station-to-data-centre fibre connectivity that eliminates the terrestrial haul and third-party interconnection costs that carriers face when routing between geographically separate landing stations and data centre campuses. The Beaufort cable, a collaboration between Amazon and Vodafone connecting Ireland to the UK, is planned to land at the former ESAT 1 station at Kilmore Quay, County Wexford, on the Irish east coast, adding a further hyperscaler-backed landing position to the east coast cable infrastructure that complements the transatlantic capacity arriving at west coast Mayo and Galway landings.
