The AIMO Progress Prize 3 is closed: final submissions ended on 15 April 2026 at 11:59 PM UTC, which was 5:29 AM IST on 16 April. The source names no date for another round, but says unclaimed prize money from this round rolls over to the next competition. This page is a guide to help you prepare for the next AIMO prize.

What the program offered

The AI Mathematical Olympiad (AIMO) Progress Prize 3 was an online Kaggle competition sponsored by XTX Investments Limited. It is the third progress prize under the AIMO Prize, a US$10 million fund created to spur the open development of AI models that can reason mathematically as well as top human participants in the International Mathematical Olympiad. The total fund for this round was US$2,207,152 (about ₹21 crore).

The prizes for the five top-ranking teams were US$262,144 (about ₹2.49 crore) for first place, then US$131,072, US$65,536, US$32,768 and US$16,384. The highest-ranking team scoring at least 47 out of 50 on both public and private test sets would also have taken the rest of the fund as Overall Progress Prize Winner, at least US$1,589,248 (about ₹15.1 crore). If nobody reached that score, the remainder would roll over to the next competition. A further US$110,000 went to additional prizes: Longest Leader (US$20,000), Hard Problem (US$30,000), Math Corpus (US$30,000) and two Writeup prizes of US$15,000 each.

Who could enter

Entrants needed a registered Kaggle account, and only one. They had to be at least 18 or the age of majority where they lived, if higher. Residents of Crimea, the so-called Donetsk and Luhansk People's Republics, Cuba, Iran and North Korea could not enter, nor anyone under US export controls or sanctions. The rules say the contest was open to residents worldwide apart from those, and India was not excluded. Individuals and teams of up to 20 could enter. Employees and contractors of XTX, Kaggle and their affiliates could take part but could not win prizes.

How the competition worked

The round began on 20 November 2025. Teams built models to solve 110 original problems in algebra, combinatorics, geometry and number theory, from national olympiad level up to IMO standard, written in LaTeX. Every answer was an integer from 0 to 99999. Submissions were Kaggle notebooks with internet access off, sent through an evaluation API at one submission a day. The entry and team-merger deadline was 8 April 2026. Kaggle supplied H100 machines for the competition.

How winners were chosen

During the contest notebooks were scored on a public test set. After the deadline each selected notebook was run twice on the private test set and scored on a penalised accuracy: 1 for both answers right, 0.5 for one right, 0 for none. Winners were decided by the private leaderboard. Potential winners had to hand over reproducible code, data and weights, release the winning code and model under an open-source licence that allows commercial use, pass identity and address checks, and return prize documents within two weeks. Prizes were to be paid roughly 30 days after the sponsor received those documents.

About the organisers

XTX Markets is a London trading firm; XTX Investments Limited sponsored this round. Kaggle hosted the competition on the sponsor's behalf.

Preparing for the next round

Earlier progress prizes opened in April 2024, October 2024 and November 2025, but no date for the next has been announced in the source. The Kaggle page now shows the competition as a late-submission entry. A practical tip: study the public leaderboard notebooks and the reference problems, practise with open-weight models inside a notebook with no internet, and set up a Kaggle account and a team early. Another tip: winners must publish their work under an open licence, so avoid proprietary tools. Taxes on prizes are the winner's responsibility; winners fill US tax forms (Form W-8BEN for a winner living outside the US), and Indian winners should take advice on tax before accepting.
