Model vs Closing Market

Strong Disagreement

The model rates Alianza Petrolera considerably stronger than the closing betting market.

Largest probability gap: Alianza Petrolera +11.1 pp

Outcome Model Closing Market Difference Signal
Alianza Petrolera 57.8% 46.7% +11.1 pp Model Edge
Draw 25.4% 30.2% -4.8 pp Aligned
Fortaleza FC 16.8% 23.1% -6.3 pp Market Higher

The statistical model estimates Alianza Petrolera's win probability at 57.8%, compared with the closing market's implied probability of 46.7%, a difference of 11.1 percentage points. This highlights a substantial disagreement between the model's assessment and the market consensus, rather than 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 result was Draw 1–1.

Market Assessment

The statistical fair estimate is materially higher than the market on Alianza Petrolera.

  • The model may see a slower-scoring or closer matchup than the market.
  • Monitor line movement before kickoff — not a betting recommendation.

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: Categoría Primera A
  • Fixture: Alianza Petrolera vs Fortaleza FC
  • Kickoff: 2026-07-26 23:10:00
  • 1X2 (model): Home 57.8% · Draw 25.4% · Away 16.8%
  • xG (showing): Alianza Petrolera 2.02 — Fortaleza FC 0.88 (total xG ≈ 2.9)
  • 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 44.6% · Over 2.5 55.4%); BTTS Yes (Yes 52.0% · No 48.0%) Value lean (pricing): O/U 2.5 Over 2.5; BTTS Yes
  • BTTS (model): Yes 52.0% · No 48.0%
  • Correct score (top bin): 2-0 (11.2%)

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.

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

Historical Recommendation

Historical Decision: Monitor

Outcome: Missed — Pre-match 1X2 lean did not match 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%).
