The USAII Global AI Hackathon 2026 was a virtual student competition across high-school, undergraduate and graduate/doctoral tracks. USAII now publishes retrospective results, and the organizer-managed Devpost page explicitly marks the event ended. No future hackathon application cycle was announced on the pages checked November 4, 2026.
Verified 2026 history: Devpost rules list registration April 26–June 6, a June 7–10 qualifier, June 14–21 build sprint and June 21, 11:59 p.m. ET project deadline. Registration closed June 6 at 11:59 p.m. ET. Teams needed a qualifier approval code, a 3–5 minute pitch and an accessible AI demo. The overview’s headline window ends June 22, but its detailed build rules end June 21. USAII’s timeline gives judging June 22–25, while Devpost rules give June 22–26; both give June 27 awards.
The detailed 2026 rules require teams of 2–5 and allow part-time employment while excluding full-time work in specified AI/data/software fields. USAII’s site uses a broader working-professional exclusion, and its retrospective FAQ says participants could enter individually or in teams. Those differing instructions are disclosed rather than treated as confirmed rules for a new cycle. The earlier free-entry description was not reverified on the current pages.
The published prize pool was US$15,000+ overall, with US$5,000 per track: US$2,500 first, US$1,500 runner-up, US$500 third and US$250 each for responsible-AI and social-impact awards, plus certification scholarships. This is historical 2026 funding, not a future award promise.
