About Primera B
Primera B is the second tier of Chile football with 16 teams. The 2026 season has produced 2.63 goals per game over 230 matches: both teams scored in 55%, 47% went over 2.5 goals, and the home side won 44% with 30% drawn. Cobreloa lead the table on 54 points from 29 games.
How the model handles Primera B
Every Primera B fixture is scored by the same calibrated model that covers 164+ competitions: home, draw and away probabilities from a result classifier, and both-teams-to-score and over/under goals from a Poisson goal model, each passed through its own calibration layer so a displayed 70% means roughly 70%. Since predictions were frozen at kickoff on 27 Jul, the model has settled 23 Primera B tips at the strict thresholds, claiming 66.9% on average and landing 43.5%. Its best-calibrated Primera B market so far is home or draw (81.6% claimed against 75.0% hit over 8 tips). Predictions appear up to three days before kick-off and are re-scored every morning until the match starts, then frozen for good.
Frequently asked questions
- How are these Primera B predictions made?
- Each match gets probabilities from two machine-learning models trained on results since 2021: a three-way result classifier for home, draw and away, and a Poisson goal model for both-teams-to-score and over/under goals. Inputs are recent venue-specific form, Elo ratings, rest days, head-to-head history and, where the data exists, shot and expected-goals aggregates. Every output is passed through an isotonic calibration layer fitted on a held-out season, so the displayed percentages match real-world frequencies — the methodology page has the detail. Predictions are frozen at kickoff and never edited afterwards.
- Where does the Primera B table come from?
- It is the official standings feed from our data provider, API-Sports, refreshed nightly. We deliberately do not compute it from results ourselves: head-to-head tiebreakers, points deductions, and split, conference or Apertura/Clausura formats are all shown exactly as the competition publishes them.
- Which Primera B market is the model most reliable in?
- On settled Primera B tips since 27 Jul, the closest match between claimed and actual hit rate is home or draw: 81.6% claimed against 75.0% hit over 8 tips. The full per-market breakdown is in the record table on this page, and it is recomputed daily as matches settle.
- How far ahead are Primera B fixtures predicted?
- Up to three days before kick-off. Fixtures are imported a week ahead, each prediction is re-scored every morning as form and ratings update, and it is frozen the moment the match starts. Exact probabilities are shown to free account holders; the headline call is public. To filter Primera B by market and probability, use the Bet Finder.
