Trade: US federally charges ex-Cuba leader Raul Castro?

Market context

The question centres on whether the Trump administration will pursue federal criminal charges against Raúl Castro, the former leader of Cuba who stepped down from his official roles in 2021 but remains influential within the Cuban government. Castro is 93 years old and resides in Cuba, a jurisdiction with no extradition treaty with the United States. Any prosecution would require either Castro's voluntary surrender, a dramatic shift in US-Cuba relations enabling his capture, or charges filed in absentia.

Historical precedent suggests low probability for such action. The US has not successfully prosecuted Cuban leadership figures despite decades of adversarial relations. The Trump administration's first term (2017–2021) pursued a hardline Cuba policy, yet did not initiate charges against Castro or other senior officials. Comparable cases involving ageing foreign leaders—such as prosecutions of Sudanese or Libyan figures—typically require either regime collapse, international tribunal involvement, or extraordinary diplomatic circumstances. The current 14% implied probability on Polymarket's order book reflects scepticism about these conditions materialising within the 18-month window.

Traders should monitor announcements regarding US-Cuba diplomatic shifts, any major escalation in sanctions policy, or statements from the Trump administration's foreign policy team regarding Cuba strategy. Recent reporting on US-Cuba relations remains largely focused on migration and economic sanctions rather than criminal prosecution of historical figures. The absence of active investigation or indictment preparation as of late 2024 suggests the market's low probability reflects genuine structural barriers rather than mere political reluctance.

How this market resolves

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.

How to trade this market step by step

The mechanics for trading "US federally charges ex-Cuba leader Raul Castro?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.

3. Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.
4. Size your position. If you stake 100 USDC at 14% YES, you'll receive shares that pay $714 if YES resolves true — a 614% gross return. If NO resolves, your shares are worth $0.

6. Wait for resolution. When the event resolves on-chain via the UMA optimistic oracle, the winning side settles to 100¢ automatically and USDC hits your balance within seconds. Withdrawable to any wallet you control.

How active is this market?

$73K in lifetime turnover and $11K of resting liquidity puts this market in the above the median by volume for trump contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.

Last 24 hours alone saw $15 in turnover, consistent with the market's lifetime daily-average pace.

The market has been open for 2 months — the price has had time to stabilise as new information arrived.

Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.

Key terms

YES / NO share

A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.

CLOB

Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.

Liquidity

USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.

UMA optimistic oracle

The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.

Slippage

The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.

Conditional token

ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Frequently asked questions

Risk and regulatory note

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.

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.
