Model vs Closing Market

Moderate Disagreement

The closing market prices NEC Nijmegen higher than the statistical model.

Largest probability gap: NEC Nijmegen -5.6 pp

Outcome Model Closing Market Difference Signal
Groningen 39.6% 34.0% +5.6 pp Model Higher
Draw 25.4% 25.3% +0.0 pp Aligned
NEC Nijmegen 35.0% 40.6% -5.6 pp Market Higher

The closing market estimates NEC Nijmegen's win probability at 40.6%, compared with the model's estimate of 35.0%, a difference of 5.6 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 (Groningen win 2–1).

Market Assessment

The market and model broadly agree on NEC Nijmegen. 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 3.35) — 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 Groningen higher (45.2% vs model 39.6%, 5.6 pp), but the model's lean was validated (Groningen 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

Below is a compact, numbers-first snapshot aligned with the same engine as the cards above.

  • League: Eredivisie
  • Fixture: Groningen vs NEC Nijmegen
  • Kickoff: 2026-05-10 14:45:00
  • 1X2 (model): Home 39.7% · Draw 25.4% · Away 35.0%
  • xG (showing): Groningen 1.73 — NEC Nijmegen 1.62 (total xG ≈ 3.35)
  • Value headline: At least one tracked line reaches the headline EV threshold — align with the hero / Primary card if shown.
  • Structural leans (not bets): Structural lean (model): O/U 2.5 Over 2.5 (Under 2.5 34.9% · Over 2.5 65.0%); BTTS Yes (Yes 67.3% · No 32.7%) Value lean (pricing): O/U 2.5 Over 2.5; BTTS Yes
  • BTTS (model): Yes 67.3% · No 32.7%
  • Correct score (top bin): 1-1 (9.8%)

Saying “no value” on a snapshot is a feature, not a bug: it protects readers from forcing a play when the edge is not there.

Prefer skipping to over-staking when the engine is honest about missing edge.

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%).
