Market context

Raúl Castro is not in U.S. custody and would need to be physically detained or transferred into the control of U.S. authorities before the end of June for this market to resolve Yes. The current price around 30% implies some chance of an extraordinary legal or security development, but the bar is high: the target is a former Cuban leader in Cuba, where U.S. jurisdiction is limited and any custody event would likely require regime collapse, a negotiated handover, or detention outside Cuba.

The closest factual frame is the long-running U.S. case over the 1996 Brothers to the Rescue shoot-down, which the Justice Department said was unsealed in a superseding indictment in May 2026 naming Raúl Castro and five other Cuban officials. DOJ said the charges relate to murder, conspiracy to kill U.S. nationals and aircraft destruction, but indictment is not custody. Historically, markets should distinguish between legal escalation and physical control: sealed warrants, indictments, and sanctions can move headlines without changing the practical odds of arrest. In crypto terms, the market settles in USDC, so price can gap on headline risk but the outcome still depends on a real-world custody transfer, not court paperwork or diplomatic rhetoric.

Traders should watch for any further DOJ filings, extradition language, or White House/Cuba policy statements, as well as any reporting on Castro’s health, travel, or status in Havana. Reuters and AP coverage of the May indictment will be the key baseline, with any follow-up on Cuban internal security or third-country detention the main catalyst. On-chain, a sharp BTC or ETH risk move could lift speculative flow into event contracts, but the settlement path here remains fundamentally binary and dependent on an actual U.S. custodial hold before 2026-06-30T00:00:00Z.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

Where can I trade this market with the lowest fees?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

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.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

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.
