Resolution criteria on PolyGram: This market will resolve to “Yes” if any justice of the Brazil Supreme Federal Court (STF) is permanently removed from the court as a result of impeachment or a trial for a crime of responsibility by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. Justices leaving the court due to term limits, voluntary resignation, or any other reason not resulting from impeachment or a trial for a crime of responsibility will not count. Impeachments, trials for crimes of responsibility, suspensions, or other procedural measures will not alone suffice to resolve this market if they do not result in the permanent removal of a justice from the Brazil Supreme Federal Court.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Any Brazil STF Justice removed by impeachment before 2027? | 14% YES | 86% NO |
Brazil's Supreme Federal Court (STF) operates with eleven justices who serve until mandatory retirement at age 75. Removal through impeachment or a trial for crimes of responsibility represents an exceptionally rare outcome in Brazilian constitutional history. The current 14% implied probability on Polymarket's order book reflects the low baseline frequency of such proceedings reaching completion and resulting in permanent removal, balanced against the court's elevated political salience in recent years.
Historical precedent provides limited guidance. No STF justice has been successfully removed through impeachment since the 1988 Constitution took effect. The impeachment process requires a two-thirds majority in the Chamber of Deputies to initiate proceedings, followed by trial in the Senate, creating a high procedural threshold. Crimes of responsibility trials, handled separately, have similarly resulted in no permanent removals of sitting justices. The court's institutional independence and the political costs of removing a justice have historically insulated members from successful removal attempts, even during periods of significant institutional conflict.
Current catalysts centre on ongoing investigations and political tensions. Justice Alexandre de Moraes faces persistent criticism from right-wing political figures and media outlets regarding his conduct in cases involving election security and January 2023 unrest allegations. However, formal impeachment proceedings require congressional initiation, and the current composition of the Chamber of Deputies lacks the political consensus necessary to advance such measures. The settlement window extends through 31 December 2026, capturing the final year of President Lula's term, when institutional pressures may shift.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
