AmCham’s 2026 US–Ireland Business Report, “A Partnership that Delivers: Supporting the Next Generation of Transatlantic Business” highlights the strength and continued evolution of the economic relationship between Ireland and the United States.

The report tells the story of one of the most dynamic and deeply embedded economic partnerships in the world – a two-way investment relationship that supports jobs, innovation and prosperity on both sides of the Atlantic. Today, American companies employ approximately 245,000 people in Ireland, while Irish companies employ over 200,000 people across all 50 US states. Ireland is now the fifth largest source of foreign direct investment into the United States, with Irish companies having invested $390 billion in the US economy.

Companies operating across the US–Ireland corridor continue to invest in high-value sectors including advanced manufacturing, life sciences, digital technologies and artificial intelligence, strengthening research capability and supporting the development of world-class talent.

Throughout the report, contributions from business leaders, policymakers and stakeholders across Ireland, the United States and Europe explore the opportunities and challenges shaping the next phase of transatlantic growth. These perspectives highlight the factors that continue to attract US investment to Ireland while examining how Ireland can further strengthen competitiveness, infrastructure, energy resilience and talent development.

Contributors include An Taoiseach Micheál Martin, Government ministers, European policymakers, enterprise agencies and business leaders from across the AmCham membership. The report also includes economic analysis from leading economist Joseph Quinlan, alongside insights from AmCham President Mark Cockerill, AmCham CEO Paul Sweetman, and leaders from multinational and Irish companies operating across the transatlantic economy.

Together, these insights highlight how Ireland and the United States can continue to deepen a partnership that delivers innovation, investment and opportunity for the next generation of transatlantic business.
