Model vs Closing Market

Strong Disagreement

The closing market prices Fortuna Köln higher than the statistical model.

Largest probability gap: Fortuna Köln -17.6 pp

Outcome Model Closing Market Difference Signal
Fortuna Köln 41.8% 59.4% -17.6 pp Market Higher
Draw 25.7% 22.7% +3.0 pp Aligned
Sportfreunde Siegen 32.6% 17.9% +14.7 pp Model Edge

The closing market estimates Fortuna Köln's win probability at 59.4%, compared with the model's estimate of 41.8%, a difference of 17.6 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 (Fortuna Köln win 2–1).

Market Assessment

The market is materially more optimistic about Fortuna Köln than the current fair estimate.

  • Investors may be incorporating information not fully reflected in the baseline model.
  • Tournament-specific context can shift market pricing.

Market lesson

Large model–market gaps do not automatically mean the market is right. Here the closing market priced Fortuna Köln higher (59.4% vs model 41.8%, 17.6 pp), but the model's lean was validated (Fortuna Köln win 2–1).

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: Regionalliga - West
  • Fixture: Fortuna Köln vs Sportfreunde Siegen
  • Kickoff: 2026-05-09 12:00:00
  • 1X2 (model): Home 41.8% · Draw 25.7% · Away 32.6%
  • xG (showing): Fortuna Köln 1.45 — Sportfreunde Siegen 1.25 (total xG ≈ 2.7)
  • 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 42.3% · Over 2.5 57.7%); BTTS Yes (Yes 66.0% · No 34.0%) Value lean (pricing): O/U 2.5 Over 2.5; BTTS Yes
  • BTTS (model): Yes 66.0% · No 34.0%
  • Correct score (top bin): 1-1 (11.0%)

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: 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%).
