In 2010, IBM created the Smarter Cites Challenge to address critical issues of the 21st century through its digital expertise, in collaboration with city governments. Despite questions about the origin and intentions of IBM's involvement, 130 cities from all around the world took up the challenge in the first five years. There is limited case study research available on a number of participating cities which has not been able to unpack cities' rationale for working with IBM. This paper provides an index of all participating cities in the Smarter Cities Challenge, to understand the areas of interest in which urban governments have been seeking IBM's consulting service. Findings present the state of smart city thinking in urban governments, and raise questions about the multidimensional integration, if any, across the areas of focus in which digital technologies are shaping contemporary cities.
