This market will resolve to the individual who first assumes office as Brazilian Chief of Staff of the Presidency (Ministro-Chefe da Casa Civil) in the government of the President of Brazil whose term begins on January 5, 2027. To count for resolution, the individual must be formally appointed to that government by the President of Brazil. An individual serving as Chief of Staff at the end of the previous term who is reappointed or retained in that position at the start of the new term will count as assuming office in that government. Any interim or caretaker Chief of Staff will not count toward the resolution of this market. Once a qualifying individual assumes office, subsequent replacements will not affect resolution. The individual must be appointed as “Chief of Staff” or be appointed to the ministerial position confirmed to be its successor position, retaining its primary responsibilities, by a consensus of credible reporting. Positions that assume only secondary responsibilities will not qualify as a successor. If the primary portfolio responsibilities previously assigned to Chief of Staff are attributable to multiple successor positions, this market will resolve to the individual appointed to one of the successor positions whose full name comes first in alphabetical order. If no such Chief of Staff assumes office by February 28, 2027, 11:59 PM ET, this market will resolve to “Other”. The primary resolution source for this market will be official information from the Government of Brazil; however, a consensus of credible reporting may also be used.
