Model vs Closing Market

Moderate Disagreement

The closing market prices GIL Vicente higher than the statistical model.

Largest probability gap: GIL Vicente -5.8 pp

Outcome Model Closing Market Difference Signal
GIL Vicente 42.5% 48.3% -5.8 pp Market Higher
Draw 31.1% 28.2% +2.9 pp Aligned
Rio Ave 26.5% 23.6% +2.9 pp Aligned

The closing market estimates GIL Vicente's win probability at 48.3%, compared with the model's estimate of 42.5%, a difference of 5.8 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 (GIL Vicente win 1–0).

Market Assessment

The market and model broadly agree on GIL Vicente. 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

  • Low-scoring profile materialised (ΣxG 2.18, 1 goals)
  • Both Teams To Score (No) matched the full-time result
  • Under 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 GIL Vicente higher (48.3% vs model 42.5%, 5.8 pp), but the model's lean was validated (GIL Vicente win 1–0).

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: Primeira Liga
  • Fixture: GIL Vicente vs Rio Ave
  • Kickoff: 2026-08-09 19:30:00
  • 1X2 (model): Home 42.4% · Draw 31.1% · Away 26.5%
  • xG (showing): GIL Vicente 1.22 — Rio Ave 0.96 (total xG ≈ 2.18)
  • Value headline: None — no positive EV on tracked lines at current best prices (same as the decision block: no default bet).
  • Structural leans (not bets): Structural lean (model): O/U 2.5 Under 2.5 (Under 2.5 62.8% · Over 2.5 37.2%); BTTS No (Yes 45.2% · No 54.8%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS No
  • BTTS (model): Yes 45.2% · No 54.8%
  • Correct score (top bin): 1-0 (13.8%)

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: 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%).
