Rio mayor Eduardo Paes eyes governorship in October election
Rio de Janeiro Governor Election Winner
Polymarket prices this Eduardo Paes at 85%. The market is more confident than the current reporting.
The Rio de Janeiro gubernatorial election will be held on Oct. 4, 2026, with a possible runoff on Oct. 25, as voters decide who will lead Brazil’s second‑largest state. Mayor Eduardo Paes, who has overseen the city’s post‑Olympic redevelopment, is the front‑runner, positioning the race as a test of his statewide appeal ahead of the 2026 national elections. Traders assign 85% to Paes, even though coverage notes his campaign infrastructure remains under construction.
Background
Eduardo Paes, serving his second term as Rio’s mayor, has built a national profile through high‑visibility projects such as the 2016 Olympics legacy program. The governorship of Rio de Janeiro, Brazil’s most populous state, has been a stepping stone for politicians seeking higher office. The 2026 race follows the 2022 election, which required a runoff after no candidate achieved a majority. The contest will be decided by a consensus of credible reporting once official results are announced.
The precedent
- Rio de Janeiro gubernatorial elections are held every four years on the first Sunday of October
- If no candidate reaches a majority, a runoff is held on the last Sunday of October, as occurred in the 2022 election

How outlets frame it
- Valor International: Emphasizes the strategic calculations of Paes’s campaign and the possibility of an indirect election scenario, framing the race as a pivotal test for his political future.
What to watch
Voters will cast ballots on Oct. 4, 2026, and if no candidate clears 50% a second round follows on Oct. 25; a shift in 85% after the first‑round results could signal market reassessment of Paes’s chances.
