Model vs Closing Market

Strong Disagreement

The closing market prices NAC Breda higher than the statistical model.

Largest probability gap: NAC Breda -10.2 pp

Outcome Model Closing Market Difference Signal
NAC Breda 26.9% 37.0% -10.2 pp Market Higher
Draw 28.1% 24.8% +3.3 pp Aligned
Heerenveen 45.0% 38.2% +6.9 pp Model Higher

The closing market estimates NAC Breda's win probability at 37.0%, compared with the model's estimate of 26.9%, a difference of 10.2 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 result was NAC Breda win 2–0.

Market Assessment

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: NAC Breda vs Heerenveen
  • Kickoff: 2026-05-10 14:45:00
  • 1X2 (model): Home 26.9% · Draw 28.1% · Away 45.0%
  • xG (showing): NAC Breda 1.17 — Heerenveen 1.57 (total xG ≈ 2.74)
  • Primary / headline line (Betting Primary Pick when shown): Under 2.5 goals
  • Model: 48.4% · Implied: 37.1% · Probability edge: +11.3 pts · Est. EV: +30.7%
  • BTTS (model): Yes 56.2% · No 43.8%
  • Correct score (top bin): 1-1 (11.9%)

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.

Correct score remains high-variance even when a line is most likely on paper.

Historical Recommendation

Historical Decision: Monitor

Outcome: Missed — Pre-match 1X2 lean did not match 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%).
