Ex-Cuba leader Raul Castro in US custody by 2026?

Platform comparison

Active sub-markets

Market context

Polymarket has this contract at 28% yes, implying traders think U.S. custody of Raúl Castro by 30 June is possible but still not the base case. On Polymarket’s on-chain rails, that view is expressed with USDC on Polygon and settled through conditional tokens, so the price is a direct read on how much probability users assign to an actual physical handover, arrest or detention by U.S. personnel.

The comparison set is thin. The strongest precedent is the Justice Department’s recent unsealing of a superseding indictment against Castro and five Cuban officials over the 1996 Brothers to the Rescue shoot-down, which keeps the case legally live but does not itself create custody. In practice, old foreign indictments often remain symbolic unless the subject travels, is extradited or is otherwise seized in a third country. At 94, Castro is also far more likely to remain beyond U.S. reach than to appear in a scene where U.S. personnel physically take control.

For the market to move, traders should watch for any change in Washington’s posture, an arrest warrant being activated abroad, or a diplomatic or security event that puts Castro in a jurisdiction where U.S. authorities could act. Reuters reported on 22 May that U.S. officials are moving ahead with the indictment, which matters because it keeps the story active, but the contract requires custody, not charging language. The main dependency is straightforward: without Castro travelling, being detained by a partner government, or some exceptional U.S. operation, the yes path remains narrow before the June deadline.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
