The eminent roster for the upcoming Global Citizen Festival continues to grow. The event’s organizers announced a slew of activists Monday who will appear on-stage as part of the one-day festival, which is set for Sept. 26 on Central Park’s Great Lawn. The additions include Malala Yousafzai, Leonardo DiCaprio, Bono, Richard Branson, Ban Ki-Moon, Bill and Melinda Gates, and Mark Zuckerberg, along with numerous dignitaries and business luminaries.

The Global Citizen Festival aims to combat poverty, inequality, and climate change throughout the world. Last month, organizers named Stephen Colbert, Hugh Jackman, Kerry Washington, Salma Hayek, Olivia Wilde, and Deborra-Lee Funess as co-hosts of this year’s event, which features headlining performances by Beyoncé, Coldplay, Ed Sheeran, and Pearl Jam. “I am honored and thrilled to join Global Citizen in urging world leaders to commit to ending extreme poverty,” Colbert said following that announcement. “Finally, all that U.N. traffic will have a purpose!”

The festival will stream on MSNBC’s website and YouTube.
