Modeling the 2026 World Cup bracket got more interesting with the new 48-team format
I've been looking into the 2026 World Cup format and realized the bracket logic is a lot less straightforward than in previous tournaments.
With 48 teams, 12 groups, a Round of 32, and the "best third-placed teams" rule, the knockout path depends on more than just who finishes 1st and 2nd in each group. That makes it an interesting little modeling problem, especially if you want to let users simulate the tournament from group stage to final.
I built a small interactive bracket predictor around that structure:
The main thing I wanted to test was whether the flow makes the new format easier to reason about:
- predict group standings
- determine which third-place teams advance
- generate the Round of 32
- continue the knockout bracket from there
Would be curious to hear how people here would approach this from an analytics/modeling perspective, especially around ranking third-place teams, simulating paths, or adding probability-based predictions later.
