Trade: Will Trump be impeached by June 30?

Market context

The House of Representatives would need to vote to impeach President Trump before 30 June 2026. Impeachment requires only a simple majority in the chamber, currently controlled by Republicans with a 222–213 seat advantage. Senate conviction or removal from office is not required for this market to resolve affirmatively—only the passage of articles of impeachment by the House.

Historical precedent suggests impeachment without removal is uncommon but not unprecedented. Andrew Johnson faced impeachment in 1868 and Bill Clinton in 1998, both acquitted by the Senate. Donald Trump was impeached twice during his first term (December 2019 and January 2021), establishing that impeachment of a sitting president can occur on party-line or near-party-line votes. The current 2% implied probability on Polymarket's order book reflects the substantial Republican House majority and the absence of significant bipartisan momentum toward impeachment in early 2025.

Traders should monitor developments around potential criminal convictions, major scandals, or shifts in Republican caucus discipline that could alter impeachment calculus. The New York sentencing in Trump's criminal case occurred in January 2025, though it produced no immediate impeachment movement. Congressional investigations, particularly any led by Democratic committees if control shifts, would represent a material catalyst. The timeframe extends through mid-2026, capturing the full remainder of the current congressional session and any early legislative priorities that might trigger formal impeachment proceedings.

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 Trump be impeached by June 30?" 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.

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 1% YES, you'll receive shares that pay $10000 if YES resolves true — a 9900% 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?

$352K in lifetime turnover and $98K of resting liquidity puts this market in the top 10% by volume for senate elections contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.

Last 24 hours alone saw $5K in turnover, consistent with the market's lifetime daily-average pace.

The market has been open for 6 months — long enough that the order book is mature and price is well-anchored to fundamentals.

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.
