Model vs Closing Market

Strong Disagreement

The model rates HNK Rijeka considerably stronger than the closing betting market.

Largest probability gap: HNK Rijeka +10.4 pp

Outcome Model Closing Market Difference Signal
Istra 1961 12.7% 20.8% -8.1 pp Market Higher
Draw 24.4% 26.6% -2.2 pp Aligned
HNK Rijeka 62.9% 52.6% +10.4 pp Model Edge

The statistical model estimates HNK Rijeka's win probability at 62.9%, compared with the closing market's implied probability of 52.6%, a difference of 10.4 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: PRE5.

After full time, the result was Draw 0–0.

Market Assessment

The statistical fair estimate is materially higher than the market on HNK Rijeka.

  • The model may see a slower-scoring or closer matchup than the market.

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: HNL
  • Fixture: Istra 1961 vs HNK Rijeka
  • Kickoff: 2026-05-16 15:00:00
  • 1X2 (model): Home 12.7% · Draw 24.4% · Away 62.9%
  • xG (showing): Istra 1961 0.73 — HNK Rijeka 1.86 (total xG ≈ 2.59)
  • Best +EV line (same label as hero card when Primary thresholds are not met): BTTS No
  • Model: 54.9% · Implied: 49.9% · Probability edge: +5.0 pts · Est. EV: +4.3%
  • BTTS (model): Yes 45.1% · No 54.9%
  • Correct score (top bin): 0-1 (14.0%)

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: 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%).
