Model vs Closing Market

Moderate Disagreement

The closing market prices Chiangrai United higher than the statistical model.

Largest probability gap: Chiangrai United -7.1 pp

Outcome Model Closing Market Difference Signal
Chiangrai United 30.4% 37.6% -7.1 pp Market Higher
Draw 33.0% 29.5% +3.5 pp Aligned
Chonburi FC 36.5% 32.9% +3.6 pp Aligned

The closing market estimates Chiangrai United's win probability at 37.6%, compared with the model's estimate of 30.4%, a difference of 7.1 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 result was Chiangrai United win 1–0.

Market Assessment

The market and model broadly agree on Chiangrai United. The remaining divergence may reflect differences in team-strength assumptions rather than a directional disagreement.

  • 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

Pre-match snapshot for this fixture.

  • League: Thai League 1
  • Fixture: Chiangrai United vs Chonburi FC
  • Kickoff: 2026-09-05 11:00:00
  • 1X2 (model): Home 30.4% · Draw 33.0% · Away 36.5%
  • xG (showing): Chiangrai United 1.01 — Chonburi FC 1.13 (total xG ≈ 2.14)
  • Value headline: None — no positive EV on tracked lines at current best prices (same as the decision block: no default bet).
  • Structural leans (not bets): Structural lean (model): O/U 2.5 Under 2.5 (Under 2.5 63.9% · Over 2.5 36.1%); BTTS No (Yes 44.8% · No 55.2%) Value lean (pricing): O/U 2.5 Under 2.5; BTTS No
  • BTTS (model): Yes 44.8% · No 55.2%
  • Correct score (top bin): 1-1 (13.4%)

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.

Prefer skipping to over-staking when the engine is honest about missing edge.

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%).
