Participant registration

Register for the challenge

Tell us who you are so we can send you data releases, deadline reminders, and results — and so we can report honestly on who this competition reached.

Step 1 · here

Register with the organizers

The form below. It puts you on the announcements list and tells us who is taking part. It takes about a minute and does not give you a leaderboard entry.

Step 2 · Codabench

Join the competition to submit

Scoring, the leaderboard, and your actual submissions all live on Codabench. You must join there separately — registering here alone will not score you, and joining Codabench alone means we cannot email you.

Neither step is a deadline gate: you can register at any point while Phase 1 is open (closes Oct 18, 2026). Doing both early just means you hear about data releases and rule clarifications when they happen rather than afterwards.

What you get

Why register

Announcements that matter

Low volume

Data releases, scorer or rule clarifications, and deadline reminders — sent only when something actually changes, not on a schedule.

Teammate matching

Optional

Tell us you are looking for a team and we will put you in touch with others who said the same. Nothing is published without asking you first.

A smoother prize process

If you win

A registered contact email and Codabench username let us verify and pay out awards without chasing anyone down.
