Model vs Closing Market

Strong Disagreement

The closing market prices Sporting CP higher than the statistical model.

Largest probability gap: Sporting CP -15.8 pp

Outcome Model Closing Market Difference Signal
Sporting CP 57.0% 72.8% -15.8 pp Market Higher
Draw 24.6% 17.0% +7.7 pp Model Higher
Guimaraes 18.3% 10.2% +8.1 pp Model Higher

The closing market estimates Sporting CP's win probability at 72.8%, compared with the model's estimate of 57.0%, a difference of 15.8 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 (Sporting CP win 3–2).

Market Assessment

The market is materially more optimistic about Sporting CP 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 2.94) — 5 goals materialised
  • Sporting CP attacking xG significantly stronger (1.92 vs 1.02)
  • Both Teams To Score (Yes) matched the full-time result

What failed

  • Exact score: outside the model's top score bins

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Sporting CP higher (72.8% vs model 57.0%, 15.8 pp), but the model's lean was validated (Sporting CP win 3–2).

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: Primeira Liga
  • Fixture: Sporting CP vs Guimaraes
  • Kickoff: 2026-08-14 19:15:00
  • 1X2 (model): Home 57.1% · Draw 24.6% · Away 18.3%
  • xG (showing): Sporting CP 1.92 — Guimaraes 1.02 (total xG ≈ 2.94)
  • 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 43.7% · Over 2.5 56.3%); BTTS Yes (Yes 55.9% · No 44.1%) Value lean (pricing): O/U 2.5 Over 2.5; BTTS Yes
  • BTTS (model): Yes 55.9% · No 44.1%
  • Correct score (top bin): 1-1 (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.

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%).
