The World Cup prediction tool I developed with Codex performed in 6 knockout matches:

Win/loss direction: 3/6; Main pick or top 3 candidate scores: 2/6; Total goals: 3/6; Over/under direction: 5/6.
After further optimization and upgrades, continue predicting the matches 'Argentina vs Egypt' and 'Switzerland vs Colombia'.
This optimization reviews past matches while integrating team big data, Poisson model, and Liuyao metaphysical predictions to provide results.
The following predictions are based on 90 minutes of regular time, excluding extra time and penalties. Purely for entertainment, for reference only.
1⃣ Argentina vs Egypt
Main pick score: 1-0; Defense scores: 2-0; 2-1
Core analysis: The tool model gives Argentina about 61% win rate, expected goals 1.74-0.70. Argentina's overall strength, knockout experience, and Messi's form are still clearly superior, but they were dragged into extra time against Cape Verde in the last round, raising concerns about stamina and defensive stability.
On Egypt's side, Salah and Marmoush have counterattack threats, but overall they seem more like defending first then countering; it won't be easy to sustain pressure on Argentina in regular time.
I lean towards a narrow win for Argentina, not a big win. The most reasonable script is Argentina controlling possession and consuming time, scoring one goal through individual ability or set pieces, then reducing risk. If Egypt executes quality counterattacks, 2-1 is a score to guard against.
2⃣ Switzerland vs Colombia
Main pick score: 0-1; Defense scores: 1-1; 1-2
Core analysis: Colombia has a slight advantage, but the two sides are very evenly matched. The tool model gives Colombia about 39% win rate, Switzerland 32%, draw 29%, expected goals 1.18-1.20.
Switzerland has been very stable recently, eliminating Algeria 2-0, with midfield control and defensive discipline on point.
But Colombia's defensive quality this tournament is tougher; publicly available information shows they have only conceded 1 goal. In attack, they have Luis Díaz and other game-deciding players.
This match is not suitable for heavy single-side bets; the draw risk is high. Main pick is Colombia winning by 1 goal, based on their balanced attack-defense and slightly better individual ability up front; but if Switzerland controls the midfield pace, 1-1 could easily happen.
I checked the current real-time win rates on @Polymarket: Argentina's current win rate is 73%, Switzerland 27%, Colombia 43%.
The surface gap in Argentina's match looks significant, but in the knockout stage everyone is fighting hard, so we still need to watch out for an upset.
Currently on Polymarket, the trading volume for Argentina vs Egypt is 6.2 M. Hope there is no upset.
