The five challenge domains and their full problem statements are published on Thursday 24 September 2026. Selection opens at the same time and is first come, first served.

Until then the domains stay closed. That is deliberate: everyone gets the same statement at the same moment, and nobody starts early.

What is released on the day

• The five domains, named
• The full problem statement for each, and its constraints
• The starter repository: it already runs
• Evaluation criteria for Round 2
• The interfaces your agent will need to expose in Round 3

What you can do now

Every domain is a real problem an intelligent commerce operation has to solve every day, and each one rewards the same groundwork: reasoning loops, tool use, grounding and evaluation. Get comfortable with those and the specific domain matters less than you think.

How to choose on the day

Pick the domain whose failure modes you find interesting, not the one that looks easiest. Round 3 pods are built with one specialist per domain, so your choice also decides the seat you hold inside a five-agent system. Selection is first come, first served, so decide quickly.

Domains open 24 September 2026. Round 2 opens the following day.
