Roger Gronerth Pinedo of Somos Perú secured a decisive plurality in the October 4, 2026, Maynas provincial mayoral election, driving the market’s 95.2% consensus on his victory. With over 93% of actas processed, he captured approximately 33.5% of valid votes, outpacing Joel Parimango Álvarez (Alianza para el Progreso) at 16.3%, Sergio Donayre Ramírez (Renovación Popular) near 11.7%, and Boris Morey Sifuentes (Fuerza Popular) around 11.5%. Earlier 2026 polling showed a fragmented field with shifting leads, yet Gronerth consolidated support in the Iquitos metropolitan districts to establish a margin exceeding 17 points. Peru’s first-past-the-post rules for municipal contests favor such pluralities without runoffs. Late-stage challenges remain possible through pending acta reviews or electoral court rulings, though the scale of the lead limits realistic reversal scenarios before final certification.
