Kenya’s sporting ambitions have taken a significant step forward following the announcement of a landmark agreement between President William Ruto and NBA executive Masai Ujiri to develop the Nairobi Arena at the Railway City redevelopment site in Nairobi.
The project, which falls under the wider Ujiri Programme, is being developed in partnership with the Kenya Railways Corporation and the Zaria Group.
It is expected to become one of the most important sports infrastructure investments in the country’s recent history.
Unlike traditional infrastructure announcements, the Nairobi Arena is being framed primarily through a sporting lens, as a long-term investment in athlete development, elite competition, and Kenya’s ability to host global events.
For decades, Kenya has been globally recognized for its dominance in athletics, particularly long-distance running. However, officials behind the Nairobi Arena project say the country has lacked modern multi-purpose sporting infrastructure capable of supporting a wider range of disciplines at international standards.
The Nairobi Arena is designed to fill that gap.
Planned within the 438-acre Railway City redevelopment zone, the facility is expected to host basketball, indoor athletics events, volleyball, boxing, and major international tournaments, alongside concerts and entertainment programming.
At the heart of the project is Masai Ujiri, whose work in global basketball and African sports development has made him one of the continent’s most influential sporting figures.
Through the Ujiri Programme, the goal is to create a full ecosystem around sport, including training, mentorship, and pathways for young athletes to reach professional levels.
Ujiri has long argued that Africa’s sporting potential is held back not by talent, but by limited access to world-class facilities and structured development systems.
The Nairobi Arena is intended to directly address that gap.
The model follows the approach already seen in Kigali, Rwanda, where Ujiri’s Zaria Court project has integrated sport, culture, and entrepreneurship into a single development space.
The arena will sit within the larger Railway City redevelopment project led by the Kenya Railways Corporation.
Once complete, Railway City is expected to function as a modern urban district integrating transport infrastructure, commercial zones, and public spaces.
Beyond athletics and competition, the arena is also expected to drive economic activity in Nairobi.
Sports tourism, event hosting, broadcasting rights, hospitality, and creative industries are all expected to benefit from a world-class venue.
