At Keystone, we believe great cities are built through both transformative development and meaningful experiences. Indiana's largest FIFA World Cup 2026™ watch party brought thousands of Hoosiers together on Monument Circle to support Team USA and celebrate the world's game.

Together with Indy Eleven Professional Soccer, Michelob ULTRA and our community partners, we were honored to create an event that filled the heart of downtown Indianapolis with energy, connection and community.

The same vision that drove the redevelopment of 220 Meridian Tower, InterContinental Indianapolis, an IHG Hotel and now 120 Monument Circle and the Sheraton Indianapolis City Centre is driving moments like these. We are investing in the buildings, experiences and public spaces that will define the next chapter of downtown Indianapolis.

We're not just developing properties. We're helping build the future of Indianapolis.
