Trade: Will Gustavo Petro be charged in the US by...?

Market context

The market concerns whether Colombian President Gustavo Petro will face criminal charges filed by any US Federal or State jurisdiction before the end of April 2026. Petro, who took office in August 2022, has maintained contentious relations with the United States on drug policy and extradition matters. The resolution hinges on formal indictment or charge announcements from US authorities, with official government sources as the primary reference point.

Historical precedent offers limited direct comparisons, though sitting heads of state have rarely faced US criminal charges whilst in office. The cases of Manuel Noriega and Augusto Pinochet involved charges after loss of power or whilst detained abroad. Petro's current presidential immunity under Colombian law would not shield him from US jurisdiction, but prosecuting a sitting president presents significant diplomatic complications. The 0% implied probability on Polymarket's order book reflects the absence of public allegations, ongoing investigations, or indictment threats from US authorities as of today.

Traders should monitor developments regarding US-Colombia extradition disputes, particularly around drug trafficking investigations or financial crime allegations. Recent tensions have centred on Petro's criticism of US drug policy rather than personal criminal exposure. Any announcement from the Department of Justice, FBI, or state prosecutors would constitute a material catalyst. The settlement window extends through May 2026, providing roughly eighteen months for circumstances to shift materially from the current baseline of no apparent prosecutorial interest.

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 "Will Gustavo Petro be charged in the US by...?" 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.

1. Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
2. Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
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 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.
5. Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.
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?

$76K in lifetime turnover and $6K of resting liquidity puts this market in the above the median by volume for colombia contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

Last 24 hours alone saw $31 in turnover, consistent with the market's lifetime daily-average pace.

The market has been open for around a month — fresh enough that information asymmetry remains a real factor.

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.
