How It Works

1 Trillion Brackets uses Monte Carlo simulation to generate and index NCAA tournament outcomes at unprecedented scale, then tracks how many remain perfect as real games are played.

Monte Carlo in a Nutshell

For each potential game, we use advanced analytics toestimate a win probability for both teams. We then simulate full tournaments by drawing outcomes from these probabilities. Repeating this process at massive scale yields a distribution of brackets that reflects the underlying model.

  • Inputs: pre‑game strength metrics and matchup adjustments.
  • Per game: sample a Bernoulli outcome with probability \( p(\text{team A wins}) \).
  • Per bracket: propagate winners round‑by‑round for all 63 games.

Scale and Indexing

We compute and store bracket outcomes a trillion times before the tournament begins. As games finish, we filter the index to count how many simulated brackets remain consistent with reality.

Assumptions and Caveats

  • Model error exists; simulation is only as good as its inputs.
  • We report counts and frequencies; not betting advice.
