Peer-to-peer fundraising programs are growing quickly among groups that lead events that fall outside of the traditional run, walk, and ride event model. But a number of longstanding, high-profile programs are continuing to see declines, according to the peer-to-peer fundraising industry’s annual roundup. Overall, contributions to programs listed in the Peer-to-Peer Fundraising Thirty — the ranking of the 30 largest peer-to-peer fundraising programs in the US — totaled $1.62 billion in 2014. That figure represents a 2.47% drop from 2013. That decline was driven, in large part, by struggles at two of the dominant charities in the peer-to-peer fundraising world.
