Model vs Closing Market

Strong Disagreement

The model rates Seongnam FC considerably stronger than the closing betting market.

Largest probability gap: Seongnam FC +11.6 pp

Outcome Model Closing Market Difference Signal
Gimpo Citizen 32.9% 43.3% -10.5 pp Market Higher
Draw 29.6% 30.8% -1.1 pp Aligned
Seongnam FC 37.5% 25.9% +11.6 pp Model Edge

The statistical model estimates Seongnam FC's win probability at 37.5%, compared with the closing market's implied probability of 25.9%, a difference of 11.6 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 model's directional lean matched the result (Seongnam FC win 1–2).

Market Assessment

The statistical fair estimate is materially higher than the market on Seongnam FC.

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

Post Match Insights

What worked

  • Expected goals projected a high-scoring match (ΣxG 2.60) — 3 goals materialised
  • Both Teams To Score (Yes) matched the full-time result
  • Exact score 1–2 fell within the model's highlighted bins

What failed

  • 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 Seongnam FC more conservatively (25.9% vs model 37.5%, 11.6 pp), but the model's lean was validated (Seongnam FC win 1–2).

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: K League 2
  • Fixture: Gimpo Citizen vs Seongnam FC
  • Kickoff: 2026-09-06 10:00:00
  • 1X2 (model): Home 32.9% · Draw 29.6% · Away 37.6%
  • xG (showing): Gimpo Citizen 1.25 — Seongnam FC 1.35 (total xG ≈ 2.6)
  • Best +EV line (same label as hero card when Primary thresholds are not met): Seongnam FC
  • Model: 37.6% · Implied: 25.9% · Probability edge: +11.7 pts · Est. EV: +6.0%
  • BTTS (model): Yes 54.5% · No 45.5%
  • Correct score (top bin): 1-1 (12.5%)

Where EV is shown, it is estimated return per unit stake at the best tracked decimal price — not the same thing as a raw probability gap.

1X2 can look balanced even when side markets show clearer structure.

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%).
