Model vs Closing Market

Moderate Disagreement

The closing market prices O'Higgins higher than the statistical model.

Largest probability gap: O'Higgins -8.2 pp

Outcome Model Closing Market Difference Signal
O'Higgins 45.5% 53.6% -8.2 pp Market Higher
Draw 28.0% 25.4% +2.6 pp Aligned
Union La Calera 26.5% 21.0% +5.6 pp Model Higher

The closing market estimates O'Higgins's win probability at 53.6%, compared with the model's estimate of 45.5%, a difference of 8.2 percentage points. This highlights a disagreement between the model and market consensus, without indicating which view is ultimately correct.

Model probabilities are generated from the statistical xG model using a Poisson distribution. Closing market probabilities are derived from consensus closing 1X2 odds after margin removal. Values represent implied probabilities rather than betting recommendations. Closing snapshot: PRE1.

After full time, the model's directional lean matched the result (O'Higgins win 2–1).

Market Assessment

The market and model broadly agree on O'Higgins. The remaining divergence may reflect differences in team-strength assumptions rather than a directional disagreement.

  • Monitor line movement before kickoff — not a betting recommendation.

Post Match Insights

What worked

  • Expected goals projected a high-scoring match (ΣxG 2.69) — 3 goals materialised
  • Both Teams To Score (Yes) matched the full-time result
  • Over 2.5 goals aligned with the xG profile

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced O'Higgins higher (53.7% vs model 45.5%, 8.2 pp), but the model's lean was validated (O'Higgins win 2–1).

Review FAQ

How accurate was the prediction?
This page grades directional markets (1X2, Over/Under 2.5, BTTS) against the full-time result. The prediction grade reflects how many of those tracked markets matched reality.
What does xG Accuracy measure?
xG Accuracy compares the model's pre-match expected-goals profile to the actual scoreline — not whether every market hit. A strong directional review can coexist with a moderate xG accuracy score.
Why wasn't the exact score predicted?
Correct-score outcomes are low-probability tails even when the model reads the match profile well. We highlight top score bins for context; missing the exact line does not invalidate a directional review.
Does this improve the AI record?
Each finished match is logged in our validation pipeline. Aggregated hit rates and CLV studies are published separately — this page is the per-match audit trail.

AI match briefing

AI Match Summary

Pre-match snapshot for this fixture.

  • League: Primera División
  • Fixture: O'Higgins vs Union La Calera
  • Kickoff: 2026-09-06 17:45:00
  • 1X2 (model): Home 45.5% · Draw 28.0% · Away 26.5%
  • xG (showing): O'Higgins 1.49 — Union La Calera 1.2 (total xG ≈ 2.69)
  • Value headline: None (actionable) — best tracked EV is about +0.7%, still below the +2.0% minimum for a headline / default stake (no default bet).
  • Structural leans (not bets): Structural lean (model): O/U 2.5 Over 2.5 (Under 2.5 49.6% · Over 2.5 50.4%); BTTS Yes (Yes 55.7% · No 44.3%) Value lean (pricing): O/U 2.5 Over 2.5; BTTS Yes
  • BTTS (model): Yes 55.7% · No 44.3%
  • Correct score (top bin): 1-1 (12.1%)

When book depth is thin or odds are missing, EV may be unavailable even though the model still prefers one side on totals or BTTS — wait for cleaner prices or skip.

Most likely correct score stays a low-probability tail: use it for context, not as a must-bet story.

Historical Recommendation

Historical Decision: No Primary Bet

Outcome: Validated — Pre-match lean validated against the full-time result.

Risk Factors Considered Before Kickoff

  • Price movement: implied probabilities and EV move with odds.
  • Sample / data gaps: low-information leagues widen forecast bands.
  • In-play state: goals and red cards are not modelled here.
  • Scoreline variance: the most likely scoreline is still usually a low absolute probability outcome (often well below 20%).
