Mexico vs. South Korea - Consensus / Ensemble Analysis
2026 World Cup, Group A Matchday 2 | June 18/19, 2026 | Estadio Guadalajara (Akron), Mexico
Kickoff: 7:00 PM CST (03:00 CEST Fri) | Referee: Gustavo Tejera (URU)
What this is: A meta-analysis averaging three model-authored predictions (MiniMax-M3, grok-4.3, glm-5.2), all reading the new canonical architecture. All 21 calibration rules byte-identical via
build.mjs.
TL;DR
Mexico slight home favorite, but the DRAW is the modal scoreline — MEX ~46% / DRAW ~31% / KOR ~23%. Top scoreline: 1-1 (~16-22%). Consensus #1 scorers: Jiménez (MEX) / Hwang In-beom (KOR). This is a "draw suits both" top-of-table decider — Finding 12 mutual-conservation is the key analytical call.
- TOP-OF-THE-TABLE DECIDER. Both MEX + KOR on 3pts (MEX +2 GD, KOR +1). Winner wins Group A; a DRAW (4pts each) suits BOTH (mutual knockout qualification).
- Finding 12 (conservation LIVE): The textbook "draw suits both" scenario — but ASYMMETRIC. MEX at home (~95% pro-MEX crowd, aggressive Aguirre) pushes for the win; KOR (pragmatic Hong) more likely to accept the point. Draw elevated but not a full mutual-conservation 0-0.
- MEX home advantage HUGE (Guadalajara, Chivas's own Akron stadium, ~95% crowd).
- Altitude ~1566m (Finding 11): ~half the Mexico City pace-tax. Moderate late-game fatigue adjustment, not the full rate.
- MEX Montes SUSPENDED (red MD1) → Álvarez makeshift CB (Finding 4 mild, -3-5pt). Attack unchanged (Jiménez + Quiñones).
- KOR Son (33, 0G/8 shots MD1): Finding 16 age-decline watch — demoted to KOR #2 behind Hwang In-beom. HIGH sub risk (Oh Hyeon-gu).
- Referee Tejera: strict career (5.1 Y/gm, 0.44 pens) BUT lenient tournament (2.6 Y/gm, 0 pens in 10 tourney games) → ~25-35% pen band, 3-5Y, neutral confed.
- ⛔ LINEUPS cross-source verified (ESPN + Sporting News + feed agree) but official team-sheet NOT 100% confirmed at T-47. Flagged PROJECTED.
Watch: Does MEX's home desperation override the mutual-conservation logic, or do both teams settle for the point that qualifies both?
1. Win Probability Consensus
| Model | Mexico | Draw | Korea |
|---|---|---|---|
| mm3 | 46% | 32% | 22% |
| g4 (grok-4.3) | 48% | 30% | 22% |
| g5 (glm-5.2) | 45% | 30% | 25% |
| Consensus | ~46% | ~31% | ~23% |
Tight — MEX within 3pts across models. Draw 30-32% (elevated, mutual-conservation). KOR 22-25%.
g4 outlier check ✅
g4 is NOT an outlier. Correctly capped MEX at ~48-50% (resisted home-co-host bullishness). Draw respected at 30%. The self-correction worked.
2. Scoreline Consensus
| Score | mm3 | g4 | g5 | Consensus |
|---|---|---|---|---|
| 1-1 Draw | 12% | 22% (#1) ⚠️ | 16% (#1) | ~16-17% (modal) |
| MEX 2-1 | 10% | 18% | 12% | ~13% |
| MEX 1-0 | 9% | 15% | 15% | ~13% |
| 0-0 | 7% | — | 10% | ~6-8% |
g4 is again heavier on the modal 1-1 (22%) — classic g4 margin concentration. Consensus ~16-17%.
3. Who Scores Consensus
| MEX #1 | KOR #1 | |
|---|---|---|
| mm3 | Jiménez (22%, pen taker) | Hwang In-beom (13%) |
| g4 | Jiménez (28%) | Hwang In-beom (discounted Son to #2) |
| g5 | Jiménez | Hwang In-beom (Son demoted to #2) |
| Consensus | Jiménez | Hwang In-beom (Son age-discounted to #2 per Finding 16) |
All 3 correctly demoted Son (33, profligate MD1) below Hwang In-beom. Jiménez unanimous MEX #1 (penalty taker + MD1 scorer).
4. Decision Graph Resolution
- Group context: Top-of-table decider. Both 3pts. A draw (4pts each) qualifies both → "need-to-win" = NO for both → Finding 12 conservation floor applies.
- Conservation (asymmetric): MEX home imperative + aggressive Aguirre → won't fully conserve. KOR pragmatic Hong + accept-the-point → more likely to sit. Draw elevated to 31% (top of band), but not a full mutual-conservation 0-0.
- Weather/altitude: 25-28°C, humid, possible thunderstorm; 1566m altitude = ~½ Mexico City pace-tax.
- Defense stack: MEX makeshift CB (Montes suspended, Álvarez shifts) — mild downgrade. KOR Kim Min-jae elite CB.
- Finishing gate: Jiménez in form (gate passes). Son age-declined (gate borderline).
- Synthesis: MEX ~46% (home edge pulls them above coin-flip), DRAW ~31% (conservation + mutual qualification), KOR ~23%.
5. The Single Thing to Watch
Mutual-conservation cagey vs MEX home push. Two scenarios:
- Cagey: both teams play for the point that qualifies both → 1-1 or 0-0 (KOR happy, MEX cautious of KOR's counter).
- MEX push: Aguirre goes for the group win at home → 2-1 or 1-0 MEX (risk: KOR's transition + Lee Kang-in).
The early tone (first 15') signals which path.
