Model vs Closing Market

Strong Disagreement

The closing market prices Atletico Nacional higher than the statistical model.

Largest probability gap: Atletico Nacional -28.6 pp

Outcome Model Closing Market Difference Signal
Atletico Nacional 38.9% 67.5% -28.6 pp Market Higher
Draw 29.1% 23.0% +6.1 pp Model Higher
Rionegro Aguilas 32.0% 9.5% +22.4 pp Model Edge

The closing market estimates Atletico Nacional's win probability at 67.5%, compared with the model's estimate of 38.9%, a difference of 28.6 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 (Atletico Nacional win 2–0).

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Atletico Nacional higher (67.5% vs model 38.9%, 28.6 pp), but the model's lean was validated (Atletico Nacional 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

Quick read on how the model reads this matchup.

  • League: Primera A
  • Fixture: Atletico Nacional vs Rionegro Aguilas
  • Kickoff: 2026-09-13 21:05:00
  • 1X2 (model): Home 38.9% · Draw 29.1% · Away 32.0%
  • xG (showing): Atletico Nacional 1.41 — Rionegro Aguilas 1.26 (total xG ≈ 2.67)
  • 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 50.1% · Over 2.5 49.9%); BTTS Yes (Yes 55.7% · No 44.3%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS Yes
  • BTTS (model): Yes 55.7% · No 44.3%
  • Correct score (top bin): 1-1 (12.3%)

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: 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%).
