Events don't take place in isolation. Often we want to know the likelihood of an event occurring if another one does. Conditional pairs enable forecasters to predict the probability of an event given the outcome of another, and provide forecast consumers with greater clarity on the relationships between events.

This specialized tournament showcases conditional forecasting, with one new conditional question presented each week. Over 14 months, forecasters will predict both branches of ~60 conditional questions, and at the end we will recognize our first champion of conditional forecasting.
