Model vs Closing Market

Strong Disagreement

The closing market prices FC Porto higher than the statistical model.

Largest probability gap: FC Porto -21.7 pp

Outcome Model Closing Market Difference Signal
FC Porto 57.1% 78.8% -21.7 pp Market Higher
Draw 27.3% 13.7% +13.6 pp Model Edge
Alverca 15.7% 7.5% +8.2 pp Model Higher

The closing market estimates FC Porto's win probability at 78.8%, compared with the model's estimate of 57.1%, a difference of 21.7 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 (FC Porto win 2–0).

Post Match Insights

What worked

  • Low-scoring profile materialised (ΣxG 1.93, 2 goals)
  • FC Porto attacking xG significantly stronger (1.21 vs 0.72)
  • Both Teams To Score (No) matched the full-time result

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced FC Porto higher (78.8% vs model 57.1%, 21.7 pp), but the model's lean was validated (FC Porto win 2–0).

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: FC Porto vs Alverca
  • Kickoff: 2026-08-09 17:00:00
  • 1X2 (model): Home 50.0% · Draw 50.0% · Away 0.0%
  • xG (showing): FC Porto 1.21 — Alverca 0.72 (total xG ≈ 1.93)
  • Value headline: None — no positive EV could be estimated on tracked lines at current best prices (missing odds or thin book depth).
  • Structural leans (not bets): See the Over/Under and BTTS cards for any directional lean text.
  • BTTS (model): Yes N/A · No N/A
  • Correct score (top bin): N/A

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.

Most likely correct score stays a low-probability tail: use it for context, not as a must-bet story.

Historical Recommendation

Historical Decision: Wait

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%).
