Javier Milei leads first-round betting at 58% as the incumbent seeking re-election under Argentina's two-round system, while Axel Kicillof trails at 20.5% and most other declared or potential contenders remain below 5%. Recent September-October 2026 polls from firms including QMonitor, QSocial, and Tendencias show the pair essentially tied near 31% each in first-round simulations, with roughly 25% undecided or blank and both candidates facing rejection above 50%. Traders price the outcome tightly because economic results under the current administration, opposition efforts to consolidate Peronist support behind Kicillof or alternatives like Sergio Massa, and the large pool of undecided voters could still shift first-round shares before the October 2027 vote.
