Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

Prices come from our regular polls of each venue, the oldest 3 h ago. Ages are as of when this page was built.

About this market

Live prediction market odds for "Next Brazilian Chief of Staff?". Camilo Santana leads at 53.9%. Next is Fernando Haddad at 19.3%. $7K has traded across 7 outcomes on Polymarket. The market is expected to resolve by Mar 1, 2027.

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.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
