The next federal Senate election is scheduled to take place in Brazil on October 4, 2026, in which two-thirds of the Senate’s 81 seats will be contested.
- This market will resolve according to the political party that holds the greatest number of seats in the next Brazilian Senate as a result of the next Brazilian Senate election.
- All seats, not only the ones contested in the next Brazilian Senate election, will be considered.
- In the event of a tie between multiple parties for the most seats held, this market will resolve in favor of the party whose listed abbreviation appears first in alphabetical order.
- This market's resolution will be based solely on the number of seats held by the named party in the Brazilian Senate as a result of the next Brazilian Senate election, not by any federation or coalition it may be a part of.
- If the result of this election isn't known definitively by June 30, 2027, 11:59 PM ET, the market will resolve to "Other".
Probabilities may differ due to different market structures, fees, and participant pools.
