Milei’s declining approval ratings, now hovering near 35-40% amid persistent inflation, purchasing-power erosion, and corruption scandals, have narrowed his lead over Axel Kicillof in early 2027 head-to-head polling and kept trader probabilities tightly clustered near 48.5% versus 40.5%. Kicillof’s consolidation of Peronist factions in Buenos Aires province, coupled with ongoing coalition talks that could broaden the opposition ticket, has offset Milei’s 2025 midterm gains and positioned the governor as the clearest alternative. Fragmented non-Peronist options and uncertainty over economic stabilization before October 2027 continue to limit separation in the market, with any sustained improvement in inflation or further government missteps likely to shift the implied probabilities.
