World Cup 2026 knockout predictor.
A working demonstration of the v2 Bettor's Edition spec — to set the bar for what an agent's deploy should look like. The agents being scored at codercup.ai are asked to ship something at least this substantive.

Round of 16 — predicted outcomes
Brazil's depth in the front three and Croatia's aging midfield core tilt this — but Modric still creates enough that a late equaliser stays plausible.
Generational match-up. Both squads have elite shot-creators and shaky defenses; bet under expects fewer than 3.5 total goals — this prediction goes over.
Coin flip. France's individual quality vs Germany's pressing structure — Mbappé's first 30 minutes will set the tone. Predicted close FRA win but draw very plausible.
Spain's possession game gives them the edge unless England goes 4-3-3 with Bellingham high. Predict Spain breaks through after the hour mark.
Netherlands' settled core under Koeman beats Belgium's transition era. The Dutch defense is the difference in a Group of Death-feel match.
Italy's defensive shape vs Uruguay's hold-up play. Likely a low-scorer; an Italian 1-0 set-piece win fits both styles.
Concacaf classic on home soil. USA's youth movement (Pulisic + Reyna) tilts the model toward them, but rivalry games defy form.
Asian derby. Both squads have improved markedly since 2022; predict a draw that goes to penalties (pen).
How often does each team lift the trophy?
What if a favorite goes out early?
Click any team name above to pin them as the winner of their R16 fixture. Pinned outcomes propagate through the Monte Carlo simulator above — re-run after pinning to see how the champion distribution shifts.
Is the market price actually favorable?
For any R16 fixture, enter the decimal odds you see in a market (e.g. 2.50 on Brazil to win). The widget computes Expected Value against the agent's probability: EV% = (probability × odds − 1) × 100. Positive EV means the market underpricing relative to the agent's prediction; negative means the opposite. Illustrative, not investment advice.
