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.

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

  1. 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.
  2. 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.
  3. Weather/altitude: 25-28°C, humid, possible thunderstorm; 1566m altitude = ~½ Mexico City pace-tax.
  4. Defense stack: MEX makeshift CB (Montes suspended, Álvarez shifts) — mild downgrade. KOR Kim Min-jae elite CB.
  5. Finishing gate: Jiménez in form (gate passes). Son age-declined (gate borderline).
  6. 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:

The early tone (first 15') signals which path.
