Calibrated probabilities for football matches. Every number comes from a model trained only on data known before that match — and we measure and publish how accurate we are.

Let us say this first

8,434 predictions measured: our model does not beat the bookmakers' closing line in any league. The gap ranges from 0.0153 — 0.0449 log-loss across leagues.

We put this on the front page instead of hiding it, because claiming otherwise would be a lie. Full measurement here.
