About this market

Live prediction market odds for "Jair Bolsonaro released from custody by March 31, 2027?". Yes leads at 68.5%. $11K has traded across 1 outcome on Polymarket. The market is expected to resolve by Apr 1, 2027.

This market will resolve to "Yes" if Jair Messias Bolsonaro is lawfully released from all custodial measures in Brazilian criminal proceedings between market creation and March 31, 2027, 11:59 PM ET. Otherwise, this market will resolve to "No". Custodial measures include imprisonment, preventive or pretrial detention, house arrest in any form, closed, semi-open, or open prison regimes, and any other measure in a Brazilian criminal proceeding requiring confinement in a prison, residence, or other designated place, except for the residence or curfew conditions permitted below. The release must be legally authorized and actually implemented by the deadline, ending all custodial measures. For house arrest, this means the measure has ceased to apply and he is no longer held under it or any other custodial measure. What qualifies: - Release through sentence extinction, annulment, or completion; a pardon, commutation, or amnesty; or a judicial decision, including habeas corpus, provisional release, or suspension of sentence execution. His sentence or conviction need not have ended. - Conditional release or parole (livramento condicional), including electronic monitoring, residence, or curfew conditions, provided he is no longer under house arrest or serving a sentence under a closed, semi-open, or open prison regime. What does not qualify: - Humanitarian house arrest (prisão domiciliar humanitária), including continuation, extension, or modification leaving any custodial measure in place, with or without an ankle monitor. Removing the monitor while custody continues does not qualify. - Continuous confinement at a specified address, except for specifically authorized outings, even if described as a release condition. - Announcements, signed acts, enacted laws, or release orders that are blocked, suspended, or otherwise unimplemented, including orders stayed or overturned before release. Issuance or publication alone is insufficient. - Custody transfers, temporary outings for medical treatment, court appearances, voting, or similar purposes, or escape, unauthorized absence, or noncompliance with a custodial order. - Release in one case while custody continues in another Brazilian criminal proceeding. What does not affect qualification: - Non-custodial restrictions, including passport surrender, social-media bans, reporting requirements, or ineligibility to hold public office. - Electronic monitoring alone, residence at a specified address, or a curfew, subject to the custody exclusions above. He need not physically leave his residence or have a monitor removed if it remains solely as a non-custodial restriction. - Whether the authorizing decision is final or unappealable; neither is required. - How briefly he is released, or any subsequent re-arrest, reinstatement of custody, or reversal of the authorizing measure, even shortly afterward. Once a qualifying release occurs, the outcome will not change. The primary resolution source will be official information from the Supremo Tribunal Federal (https://portal.stf.jus.br), other competent Brazilian courts, or Brazilian corrections authorities; 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.
