Model vs Closing Market

Strong Disagreement

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

Largest probability gap: Sporting CP -17.9 pp

Outcome Model Closing Market Difference Signal
Sporting CP 63.2% 81.1% -17.9 pp Market Higher
Draw 22.2% 12.1% +10.1 pp Model Edge
GIL Vicente 14.7% 6.9% +7.8 pp Model Higher

The closing market estimates Sporting CP's win probability at 81.1%, compared with the model's estimate of 63.2%, a difference of 17.9 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: PRE1.

After full time, the model's directional lean matched the result (Sporting CP win 3–0).

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 3.10) — 3 goals materialised
  • Sporting CP attacking xG significantly stronger (2.14 vs 0.96)
  • Exact score 3–0 fell within the model's highlighted bins

What failed

  • Both Teams To Score: model leaned BTTS Yes; match finished BTTS No
  • Over / Under 2.5: model leaned Under 2.5; match finished Over 2.5 (3 goals)

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Sporting CP higher (81.1% vs model 63.2%, 17.9 pp), but the model's lean was validated (Sporting CP win 3–0).

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

Quick read on how the model reads this matchup.

  • League: Primeira Liga
  • Fixture: Sporting CP vs GIL Vicente
  • Kickoff: 2026-05-17 16:00:00
  • 1X2 (model): Home 63.2% · Draw 22.1% · Away 14.6%
  • xG (showing): Sporting CP 2.14 — GIL Vicente 0.96 (total xG ≈ 3.1)
  • 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 Under 2.5 (Under 2.5 40.1% · Over 2.5 59.9%); BTTS Yes (Yes 55.6% · No 44.4%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS Yes
  • BTTS (model): Yes 55.6% · No 44.4%
  • Correct score (top bin): 2-0 (10.3%)

Saying “no value” on a snapshot is a feature, not a bug: it protects readers from forcing a play when the edge is not there.

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%).
