Model vs Closing Market

Moderate Disagreement

The closing market prices Monterrey U21 higher than the statistical model.

Largest probability gap: Monterrey U21 -8.8 pp

Outcome Model Closing Market Difference Signal
Atlante U21 35.6% 30.5% +5.2 pp Model Higher
Draw 29.6% 26.0% +3.7 pp Aligned
Monterrey U21 34.7% 43.5% -8.8 pp Market Higher

The closing market estimates Monterrey U21's win probability at 43.5%, compared with the model's estimate of 34.7%, a difference of 8.8 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 (Atlante U21 win 5–4).

Market Assessment

The market and model broadly agree on Monterrey U21. 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 2.60) — 9 goals materialised

What failed

  • Both Teams To Score: model leaned BTTS No; match finished BTTS Yes

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Atlante U21 higher (44.4% vs model 35.6%, 8.8 pp), but the model's lean was validated (Atlante U21 win 5–4).

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

Quick read on how the model reads this matchup.

  • League: Liga MX U21
  • Fixture: Atlante U21 vs Monterrey U21
  • Kickoff: 2026-09-25 18:00:00
  • 1X2 (model): Home 35.6% · Draw 29.7% · Away 34.7%
  • xG (showing): Atlante U21 1.31 — Monterrey U21 1.29 (total xG ≈ 2.6)
  • Best +EV line (same label as hero card when Primary thresholds are not met): Under 2.5 goals
  • Model: 51.8% · Implied: 45.4% · Probability edge: +6.4 pts · Est. EV: +8.8%
  • BTTS (model): Yes 54.5% · No 45.5%
  • Correct score (top bin): 1-1 (12.6%)

Where EV is shown, it is estimated return per unit stake at the best tracked decimal price — not the same thing as a raw probability gap.

Early match state can move realised goals away from pre-kick projections.

Historical Recommendation

Historical Decision: Monitor

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%).
