The Supply Chain Trading Agent Competition (TAC-SCM) has been running as an annual tournament since 2003. It revolves around a PC assembly game, where trading agents from different teams compete for both customer orders for PCs and for PC components required to assemble these PCs. Starting in 2007, the tournament introduced two new challenges: a Procurement Challenge and a Prediction Challenge.

Competitors have the option of entering any of these three events (e.g. just the baseline game, one or both challenges, etc.). Details on entry fees will be posted on the main TAC-SCM website, which also serves as home for the baseline game.
