Model vs Closing Market

Outcome	Model	Closing Market	Difference	Signal
Shanghai Port II	37.6%	44.1%	-6.5 pp	Market Higher
Draw	29.8%	28.8%	+1.0 pp	Aligned
Tai'an Tiankuang	32.7%	27.1%	+5.5 pp	Model Higher

The closing market estimates Shanghai Port II's win probability at 44.1%, compared with the model's estimate of 37.6%, a difference of 6.5 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 Tai'an Tiankuang win 2–3.

Market Assessment

The market and model broadly agree on Shanghai Port II. 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

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

League: China League Two
Fixture: Shanghai Port II vs Tai'an Tiankuang
Kickoff: 2026-07-26 08:30:00
1X2 (model): Home 45.0% · Draw 45.0% · Away 10.0%
xG (showing): Shanghai Port II 1.3 — Tai'an Tiankuang 1.3 (total xG ≈ 2.6)
Value headline: None — no positive EV could be estimated on tracked lines at current best prices (missing odds or thin book depth).
Structural leans (not bets): See the Over/Under and BTTS cards for any directional lean text.
BTTS (model): Yes N/A · No N/A
Correct score (top bin): N/A

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.

If lines move materially, re-run generation or refresh — implied probabilities and any future EV readouts will change first.

Historical Recommendation

Historical Decision: No Primary Bet

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%).
