A $100,000 high-school entrepreneurship competition run from the University of Delaware. Two tracks (Business Innovation, Social Innovation), a written concept narrative, a 60-second introductory video, a five-minute pitch, and a finals weekend at the Limitless World Summit in Wilmington, Delaware.
The Diamond Challenge is the work of Horn Entrepreneurship at the University of Delaware. It is a two-track competition — Business Innovation and Social Innovation — for teams of two to four high-school students aged 14–18, supported by one adult advisor. Each track awards a $12,000 Grand Prize, an $8,000 second prize, and a $4,500 third prize; five named Topical Prizes (the DSWA Waste & Recycling Innovation Prize, the Gore Innovation Excellence Prize, the Pathways to Prosperity Prize, the Horn Entrepreneurship Global Prize, and the Human Flourishing Award) round out a $100K+ total pool.
The competition is structured around two submitted artefacts — a written concept narrative and a short introductory video — and a pitch round. Teams may opt into a live pitch event (at one of the Pitch Event Partner locations worldwide) or a virtual pre-recorded pitch; both feed the same judging pool. Top-scoring teams advance to the finals at the Limitless World Summit.

Track selection is made at initial submission and is final. Choose by what your concept actually is — not by perceived prize odds (the 2025-26 finalist cohort was near-perfectly balanced).
| Track | Theory of impact | Judging anchors |
|---|---|---|
| Business Innovation | A concept's primary purpose is to solve a customer problem and generate revenue and profit. Growth in revenue is what scales the impact. | Business model canvas · market sizing · unit economics · team capability · competitive advantage |
| Social Innovation | A concept's primary purpose is to solve a social problem and make a positive impact on people or the environment. The people who benefit and the people who pay may differ. | Social impact canvas · theory of change · beneficiary clarity · measurement plan · sustainability model |
The official Social Impact Canvas (a one-page Beneficiaries/Payers/Impact/Resistances template) is published in the official resources — model your Social track reasoning to it.
