Bloomberg CityLab, the global cities summit organised by Bloomberg Philanthropies in partnership with the Aspen Institute to help strengthen global cooperation and share practical, city-led solutions across borders, will take place in Madrid on 27-29 April.
CityLab reports that at a time when international partnerships and cooperation are under strain, the summit will aim to foster vital connections between cities, address shared urgent challenges, and promote bold, practical solutions that are shaping the future of cities.
How cities are stepping up
“As national governments struggle to confront global challenges and traditional alliances fray, cities are stepping up. They’ve always been where progress happens – and today, empowering them isn’t optional, it’s urgent,” said James Anderson, who leads the Government Innovation program at Bloomberg Philanthropies.
“Bloomberg CityLab provides the infrastructure cities need to connect across borders, collaborate at speed, and turn ambitious ideas into real-world change.”
“CityLab Madrid will showcase the critical role of municipal leaders in addressing both national and international challenges in the face of polarisation, not through ideology, but through bold action”
The main stage discussions will focus on critical issues such as the accelerating impact of artificial intelligence on urban economies, labour markets, and governance. Also prominent on this year’s agenda are emerging solutions to the housing and affordability crises, as well as the new approaches mayors are taking to rebuild trust in an era of polarisation.
These themes will be brought to life through panel discussions, one-on-one interviews, interactive small-group sessions, artistic presentations, data visualisations, and field visits around Madrid, with the participation of mayors, urban innovators, technology entrepreneurs, and other key stakeholders.

Confirmed attendees at the summit include more than 700 mayors, public policymakers, innovators and creatives from cities in Europe, Africa, Asia, Australia, North America, and Latin America, representing more than 30 countries worldwide. The summit will be held in several iconic venues throughout the city, including the Teatro Real, the Real Teatro del Retiro, the Museo Nacional Centro de Arte Reina Sofía, and the historic Hotel Palace.
“Mayors are getting things done – they are forging stronger connections with communities and are relentless in their pursuit to improve city life. Bloomberg CityLab Madrid will showcase the vital role of city leaders in solving domestic and international challenges in the face of polarisation at the national level – not through ideology, but through bold action,” said Bunmi Akinnusotu, director of city innovation at the Aspen Institute. “This gathering is about sharing what works and then accelerating it, so that local solutions can travel farther and faster.”
Bloomberg CityLab was founded on the principle that the most important innovation is happening locally and that global impact can be achieved when cities share solutions. For more than a decade, CityLab summits have brought together the most influential mayors and leading voices from hundreds of cities around the world.
New speakers and topics will be announced in the coming weeks and published on the Bloomberg CityLab 2026 website.
