About this market

Live prediction market odds for "Will Lula announce nomination of a Supreme Court minister by...?". December 31 leads at 68.5%. Next is October 31 at 14.5%. $32K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.

This market will resolve to “Yes” if President Luiz Inácio Lula da Silva (Lula) nominates an individual for Minister (Ministro) of the Supreme Federal Court of Brazil (Supremo Tribunal Federal) by the listed date, 11:59 PM Brasilia time. Otherwise, this market will resolve to "No". An announcement from Lula or the Office of the Presidency of the Republic of Brazil (Presidência da República) stating that Lula has nominated an individual for Minister of the Supreme Federal Court will suffice to resolve this market, regardless of whether a formal nomination actually occurred. Qualifying announcements must explicitly present the relevant individual as the nominee for Minister of the Supreme Federal Court. Announcements of acting or interim appointments, announcements of intention to nominate an individual in the future, or announcements which merely reveal potential candidates will not qualify. Media reports, speculation, or other unofficial information will not qualify. A formal presidential nomination of an individual to be Minister of the Supreme Federal Court will also suffice to resolve this market. Formal nominations are defined as the submission of a nomination message to the President of the Federal Senate (presidente do Senado Federal). The primary resolution source for this market will be official information from the Presidency of the Republic of Brazil (https://www.gov.br/planalto), 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.
