Model vs Closing Market

Strong Disagreement

The closing market prices Colo Colo higher than the statistical model.

Largest probability gap: Colo Colo -13.7 pp

Outcome Model Closing Market Difference Signal
Union La Calera 30.3% 20.0% +10.3 pp Model Edge
Draw 29.9% 26.5% +3.4 pp Aligned
Colo Colo 39.8% 53.5% -13.7 pp Market Higher

The closing market estimates Colo Colo's win probability at 53.5%, compared with the model's estimate of 39.8%, a difference of 13.7 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 (Colo Colo win 1–2).

Market Assessment

The market is materially more optimistic about Colo Colo 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

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 División
  • Fixture: Union La Calera vs Colo Colo
  • Kickoff: 2026-08-09 21:30:00
  • 1X2 (model): Home 30.3% · Draw 29.8% · Away 39.8%
  • xG (showing): Union La Calera 1.17 — Colo Colo 1.37 (total xG ≈ 2.54)
  • 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 53.4% · Over 2.5 46.6%); BTTS Yes (Yes 53.1% · No 46.9%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS Yes
  • BTTS (model): Yes 53.1% · No 46.9%
  • Correct score (top bin): 1-1 (12.6%)

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%).
