  • Over / Under 2.5 Over 2.5 Under 2.5 (2 goals) ✖ Incorrect

Model vs Closing Market

Strong Disagreement

The model rates Gremio considerably stronger than the closing betting market.

Largest probability gap: Gremio +25.9 pp

Outcome Model Closing Market Difference Signal
Gremio 55.1% 29.3% +25.9 pp Model Edge
Draw 24.5% 29.4% -4.8 pp Aligned
Fluminense 20.4% 41.4% -21.0 pp Market Higher

The statistical model estimates Gremio's win probability at 55.1%, compared with the closing market's implied probability of 29.3%, a difference of 25.9 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 result was Draw 1–1.

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

Below is a compact, numbers-first snapshot aligned with the same engine as the cards above.

  • League: Campeonato Brasileiro Série A
  • Fixture: Grêmio vs Fluminense
  • Kickoff: 2026-07-26 21:30:00
  • 1X2 (model): Home 55.2% · Draw 24.5% · Away 20.3%
  • xG (showing): Grêmio 1.95 — Fluminense 1.13 (total xG ≈ 3.08)
  • Best +EV line (same label as hero card when Primary thresholds are not met): Grêmio
  • Model: 55.2% · Implied: 29.3% · Probability edge: +25.9 pts · Est. EV: +12.6%
  • BTTS (model): Yes 59.4% · No 40.6%
  • Correct score (top bin): 1-1 (10.1%)

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.

Correct score remains high-variance even when a line is most likely on paper.

Historical Recommendation

Historical Decision: Wait

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%).
