Bloomberg CityLab 2026
Madrid, Spain
April 27-29, 2026
Bloomberg Philanthropies and the Aspen Institute will host the 12th Bloomberg CityLab, the preeminent global cities summit, in Madrid, Spain on April 27 – April 29, 2026. The summit will spur vital city-to-city connections, confront urgent shared challenges, and advance bold, practical solutions shaping the future of cities—and the world.
Mainstage conversations will focus on critical issues like the accelerating impact of AI on urban economies, labor markets, and governance. Also prominent in this year’s agenda are emerging solutions to housing and affordability crises, as well as new approaches mayors are taking to rebuild trust in an age of polarization.
These topics will be brought to life through panel discussions, one-on-one interviews, interactive breakout sessions, artistic performances, data visualizations, and field trips across Madrid featuring mayors, city innovators, tech entrepreneurs, and more.
Bringing Mayors Together to Strengthen Cooperation
Bloomberg CityLab was founded on the principle that the most important innovation is happening at the local level and spreads when cities share solutions.
For over a decade, Bloomberg CityLab summits have crossed the globe, gathering the most influential leaders and voices from cities worldwide. Summits have generated tangible takeaways for attendees, with past conferences hosted in New York, Los Angeles, London, Miami, Paris, Detroit, Washington, D.C., Amsterdam, and Mexico City.
Bloomberg Philanthropies and Madrid
This year’s Bloomberg CityLab in Madrid builds on Bloomberg Philanthropies’ partnership with the municipality under Mayor José Luis Martínez-Almeida and Bloomberg Philanthropies’ expanding work to strengthen local government capacity across Europe. These efforts are part of the government innovation initiatives Bloomberg Philanthropies leads in hundreds of city halls around the world, many of whose mayors and top officials will convene in Madrid for the event.
