JPMorgan Chase’s charitable arm has pledged to dole out $5-million to grass-roots charities chosen by Facebook users, USA Today reports.

Participants in the Chase Community Giving contest can vote through December 11 for an eligible nonprofit group and encourage other users of the social-media site to follow suit. The top vote-getter will be awarded $1-million, with five runners-up getting $100,000 each and 100 other finalists receiving $25,000 apiece.

Kimberly Davis, president of the JPMorgan Chase Foundation, said the organization views the contest as a model for future “crowdsourcing” programs. “We hope that people will see this as an exciting venture in innovation and for philanthropy,” she said.
