Trade: Jack Doherty Prison Time?

Market context

YouTuber Jack Doherty was arrested in Miami in November 2024 on charges including possession of amphetamine, marijuana possession under 20 grams, and resisting an officer without violence. The market resolves based on whether he receives a custodial sentence by 31 October 2026, with settlement triggered immediately upon the first sentence handed down, regardless of subsequent appeals. The current order book implies a 1% probability of prison time, reflecting market confidence in a non-custodial outcome.

Florida's sentencing guidelines for simple drug possession typically favour probation or diversion programmes, particularly for first-time offenders without aggravating factors. The resisting charge, classified as a misdemeanour without violence, rarely results in incarceration when paired with low-level drug offences. Comparable cases involving content creators and minor drug charges have predominantly resulted in suspended sentences, fines, or community service. However, judicial discretion remains substantial; factors including prior conduct, courtroom demeanour, and prosecutorial recommendations can shift outcomes materially.

Key catalysts include the arraignment hearing schedule, which determines the timeline for plea negotiations or trial proceedings, and any discovery disclosures that might reveal additional evidence or charges. Traders should monitor Miami-Dade County court filings for motion schedules and plea agreement announcements. The settlement window extends nearly two years, allowing substantial time for case resolution, though delays in the Florida court system are commonplace. Any material changes to charges—such as felony reclassification—would meaningfully alter conviction and sentencing probabilities.

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 "Jack Doherty Prison Time?" 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 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.

How active is this market?

$19K in lifetime turnover and $2K of resting liquidity puts this market in the around the median by volume for youtube contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

The market has been open for 6 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.
