Will an agent win the $700,000 ARC-AGI-3 Grand Prize in ARC Prize 2026?

ARC-AGI-3 drops AI agents into game-like worlds with no instructions. The Grand Prize goes to the first eligible open source agent that scores 100% on the private evaluation under Kaggle's compute limits. Final submissions are due November 2, 2026, and winners are due December 4.

How this question entered the record and how it will be resolved.

Resolution criteria

Resolves Yes if ARC Prize announces on arcprize.org, by December 31, 2026, that the ARC Prize 2026 ARC-AGI-3 Grand Prize has been awarded. Resolves No if the 2026 results say it was not won, or if no award is announced by that date.

Expected resolution

Dec 31, 2026

• arcprize.org ARC-AGI-3 competition page, checked October 15, 2026: Grand Prize of $700K for the first eligible agent scoring 100%, rolls over if not won
• Tech Times, October 6, 2026: Tufa Labs led the public Kaggle board at 55.89, the Grand Prize remained unclaimed, winners announced December 4, 2026

The bar is a perfect score on a hidden set, and the leading public Kaggle entries sat well below that in early October.

• Late jumps on the public Kaggle leaderboard before November 2
• Gaps between public and private evaluation scores
