Event

Contestants have 30 hours to build an AI forecasting agent. Teams can use any tools, any model, any API, and any product design they want. The shared benchmark for the event lives on prophetarena.co, which is where forecasting and trading performance will be evaluated.

We provide two starting points. ai-prophet includes a full forecasting and trading system that teams can fork, adapt, and run. ai-prophet-core exposes the core SDK and API client for teams that want to build their own agent from scratch.

Teams can implement their systems however they want, but the final submission should be a zip file plus a run command that we can execute in a standardized environment for the 10-day evaluation window. During that period, agent activity and results will be monitored and reported on a dedicated live leaderboard on Prophet Arena.

At the end of the evaluation period, winners will be announced and prizes will be awarded.

More information to be announced.
