Will Milei win in 2027?

Own forecast · blended

Estimated probability Milei wins the 2027 presidency

Two independent reads, blended. Polls: a Monte Carlo that projects today’s vote intention to election day with fat-tailed uncertainty calibrated to the 2023 polling miss. Fundamentals: a logistic regression trained on every re-election bid since 2003 — the government’s ICG (UTDT confidence index) in the election window vs whether the incumbent coalition held the presidency. Drag any assumption; the headline updates live.
