Model vs Closing Market

Strong Disagreement

The closing market prices Benfica higher than the statistical model.

Largest probability gap: Benfica -10.5 pp

Outcome Model Closing Market Difference Signal
Benfica 75.8% 86.3% -10.5 pp Market Higher
Draw 15.4% 9.3% +6.2 pp Model Higher
Estoril 8.8% 4.4% +4.3 pp Aligned

The closing market estimates Benfica's win probability at 86.3%, compared with the model's estimate of 75.8%, a difference of 10.5 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 (Benfica win 2–1).

Market Assessment

The market is materially more optimistic about Benfica 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 3.36) — 3 goals materialised
  • Benfica attacking xG significantly stronger (2.45 vs 0.91)
  • Both Teams To Score (Yes) matched the full-time result

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Benfica higher (86.3% vs model 75.8%, 10.5 pp), but the model's lean was validated (Benfica 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

Pre-match snapshot for this fixture.

  • League: Primeira Liga
  • Fixture: Benfica vs Estoril
  • Kickoff: 2026-08-31 19:15:00
  • 1X2 (model): Home 75.8% · Draw 15.4% · Away 8.8%
  • xG (showing): Benfica 2.45 — Estoril 0.91 (total xG ≈ 3.36)
  • 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 34.8% · Over 2.5 65.2%); BTTS Yes (Yes 55.6% · No 44.4%) Value lean (pricing): O/U 2.5 Over 2.5; BTTS Yes
  • BTTS (model): Yes 55.6% · No 44.4%
  • Correct score (top bin): 2-0 (10.4%)

When book depth is thin or odds are missing, EV may be unavailable even though the model still prefers one side on totals or BTTS — wait for cleaner prices or skip.

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%).
