2018 Mayors Challenge
The time is Now

The time is now!

U.S. mayors face bigger challenges than ever before. Innovation is no longer optional; it’s necessary so cities can continue to deliver results and improve life for residents.

The 2018 Mayors Challenge, sponsored by Bloomberg Philanthropies, is designed with this urgency in mind. It’s an initiative to help city leaders think big, be bold, and uncover inventive — and, ultimately, shareable — ideas that tackle today’s toughest problems.

35 Champion Cities Have Been Selected!

35 cities have been selected to continue in the competition as Champion Cities. Finalists were selected by Bloomberg Philanthropies with the support of a prestigious selection committee. The Champion Cities will now begin a 6-month testing phase where they will conduct public prototypes of their ideas with grant funding of up to $100,000 per city.
