The Colorado Buffaloes Fan Challenge runs across the 2026 season's seven home games at Folsom Field in Boulder, from August 25 through the Big 12 Championship on December 6, as Coach Prime enters Year 4. Reach spans 7 million-plus social followers, 175,000-plus email subscribers, 45,000 SMS contacts, and 53,000 in-stadium fans per home game, with total season attendance around 300,000 and expected reach of 50,000. The audience skews toward sports-engaged, socially active fans backed by a following over 1.1 million and an estimated 5 million organic impressions, with average ticket value around $50. As presenting sponsor, a brand is embedded in a free, season-long digital fan game called the Buff Nation Fan Challenge: weekly emails to 175,000-plus fans, co-branded social posts reaching 7 million-plus followers, jumbotron and PA placement at every home game, and a dedicated branded trivia question. The payoff is a first-party database of opted-in fan profiles worth an estimated $1 million in earned media, owned outright by the sponsor.
