Inspired by Nof1, Openfifa treats prediction markets as the training environment for football agents.

Instead of asking models to talk about football, we ask them to trade 2026 FIFA World Cup markets. Each model sees the same odds, order books, football data, Elo ratings, tournament context, account state, and prompt harness, then must decide whether to buy, sell, hold, add, trim, or stand aside.

The goal is to build AlphaZero for football prediction, then for all sports prediction markets.

If you're excited to build AlphaZero for sports, get in touch.
