📊 2026 World Cup Data Analysis System | Probability Model Observation
Core Logic: Based on ELO ratings, expected goals (xG), shot conversion rate, and a historical odds database. The probability model identifies value directions by comparing model probabilities against market-implied probabilities. Below are the 3 most significant observation points from the group stage.
🔍 Observation Point 1: Draw Probability Systematically Undervalued
- Model Draw Probability Average: 29%
- Market Implied Draw Probability Average: 24%
- Average Deviation: +5%
- Model Interpretation: The market systematically undervalues draw probability in knockout stages. When both teams are closely matched (win odds difference < 1.50), the deviation expands to +7%.
- Application Direction: The draw direction offers positive long-term expected value.
🔍 Observation Point 2: Favorite Cover Rate Lower Than Market Expectations
- Model-Calculated Favorite Cover Probability: 41%
- Market Implied Cover Probability: 50%
- Average Deviation: -9%
- Model Interpretation: The market over-trusts favorites to settle matches within 90 minutes. Defense is prioritized in knockout stages, and the difficulty of favorites covering the handicap is underestimated.
- Application Direction: The underdog (+0.5) offers value.
🔍 Observation Point 3: xG Difference Reveals "Undervalued" Teams
- Denmark: Actual Goals 3 vs xG 5.8 (Difference +2.8)
- Serbia: Actual Goals 4 vs xG 6.2 (Difference +2.2)
- Model Interpretation: Teams with an xG difference of ≥ +1.5 have had below-average goal-scoring luck and may see their goal output rebound in the knockout stage.
- Application Direction: Focus on "Goals over expected" or "Unbeaten" directions.
