Resolution criteria on PolyGram: This market will resolve to “Yes” if Raul Castro is taken into U.S. government custody at any point by June 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. Raul Castro will be considered taken into U.S. government custody if U.S. government personnel (including military, CIA, personnel of another agency, or contractors acting under direct U.S. government authority) physically detain, arrest, capture, or otherwise assume physical custodial control of Raul Castro, regardless of location or duration. Visits, interactions with U.S. government personnel, or Raul Castro’s presence in U.S.
Election and policy markets historically tighten as polling firms publish their final round and prediction-market traders fade or back the consensus. Current odds favour the NO side at 30%, making this a directional market with 38 days to resolution — long enough that information asymmetry can still move the line meaningfully, backed by $53K of resting liquidity.

Market outcomes
| June 30 | 30% YES | 70% NO |
| May 31 | 8% YES | 92% NO |
The market turns on whether Raúl Castro is physically taken into U.S. government custody before 1 July 2026. The immediate trigger is the Justice Department’s unsealing of a superseding indictment over the 1996 Brothers to the Rescue shoot-down, which charges Castro and five others with murder, conspiracy to kill U.S. nationals, and aircraft destruction. That makes the case legally live, but it does not itself put him in U.S. hands. The current 23% implied probability is being formed in Polymarket’s order book from traders weighing the legal headline against the practical difficulty of any custody event, especially given Castro’s age, location in Cuba, and the lack of any obvious extradition route.
Comparable cases suggest the baseline should stay low unless there is a material change in diplomacy or movement on the ground. U.S. indictments of foreign political figures can remain symbolic for years without arrest, particularly where the subject is in a hostile or non-co-operating state. The market is therefore less about the indictment itself than about whether the U.S. can convert it into an actual transfer, detention, or capture. Recent reporting from the Los Angeles Times on 20 May said Castro is unlikely to face U.S. custody, while officials may view the indictment as leverage amid quiet talks with his grandson and wider pressure on Havana.
Traders should watch for any official DOJ follow-up, arrest warrant details, extradition signals, or changes in U.S.-Cuba contacts that would make custody more plausible. Any confirmed travel, hospital movement, or detention outside Cuba would matter only if U.S. personnel physically assumed control. Absent that, the main dependency is diplomatic: whether Washington tries to use the case as bargaining leverage, or whether it remains a public indictment with no practical path to custody before the settlement window closes.
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.
For this market, the resolution date is 30 June 2026. A UMA proposer can submit the outcome from that moment; the two-hour dispute window closes at , and assuming no counter-claim is staked, winning USDC clears to trader balances by approximately .
If a dispute is filed inside the two-hour window, the outcome escalates to UMA token-holder voting, which extends settlement by roughly 48 hours. This particular market has no public resolution feed listed; disputes here are more likely if the underlying outcome is subject to interpretation, in which case the UMA token-vote arbitrates the wording of the original market question.
Political markets occasionally see longer settlement when outcomes hinge on official certification rather than the polling result itself — the proposer waits for the certifying body's announcement, which can push payout 12-48 hours past the calendar end-date. Funds clear directly to your in-app USDC balance on Polygon. Withdrawals are non-custodial: send to any address you control, typical confirmation under 30 seconds, gas paid in USDC if you'd rather not hold MATIC.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose. For "Ex-Cuba leader Raul Castro in US custody by 2026?", the considerations above apply directly — Political markets are exposed to information asymmetry between insider and retail traders, and to last-minute polling shifts that can move the line 15-20¢ in the final 48 hours. Long-dated political contracts also carry meaningful time decay if the underlying race is close.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
