Model vs Closing Market

Strong Disagreement

The closing market prices Vitesse higher than the statistical model.

Largest probability gap: Vitesse -14.9 pp

Outcome Model Closing Market Difference Signal
Vitesse 43.2% 58.1% -14.9 pp Market Higher
Draw 25.4% 22.3% +3.0 pp Aligned
FC OSS 31.4% 19.6% +11.8 pp Model Edge

The closing market estimates Vitesse's win probability at 58.1%, compared with the model's estimate of 43.2%, a difference of 14.9 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: PRE5.

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

Market Assessment

The market is materially more optimistic about Vitesse than the current fair estimate.

  • Investors may be incorporating information not fully reflected in the baseline model.
  • Tournament-specific context can shift market pricing.

Post Match Insights

What worked

  • Expected goals projected a high-scoring match (ΣxG 3.30) — 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 Vitesse higher (58.1% vs model 43.2%, 14.9 pp), but the model's lean was validated (Vitesse 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

Quick read on how the model reads this matchup.

  • League: Eerste Divisie
  • Fixture: Vitesse vs FC OSS
  • Kickoff: 2026-09-04 18:00:00
  • 1X2 (model): Home 43.1% · Draw 25.4% · Away 31.5%
  • xG (showing): Vitesse 1.79 — FC OSS 1.51 (total xG ≈ 3.3)
  • 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 35.9% · Over 2.5 64.1%); BTTS Yes (Yes 66.2% · No 33.8%) Value lean (pricing): O/U 2.5 Over 2.5; BTTS Yes
  • BTTS (model): Yes 66.2% · No 33.8%
  • Correct score (top bin): 1-1 (10.0%)

The decision block shows no default Primary: Primary needs consensus EV ≥ +5.0% plus strength/reliability/calibration gates. A separate Lean/tracked gate is +2.0% (selective only). Lean labels are directional only — not bankroll-sized recommendations.

If lines move materially, re-run generation or refresh — implied probabilities and any future EV readouts will change first.

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%).
