Trump impeachment markets on Polymarket allow traders to bet on whether the House will impeach the President or whether the Senate will convict. These contracts have been among the most politically charged on the platform, attracting traders from across the political spectrum. This guide explains how impeachment markets work, what current prices imply, and what traders should consider.
Impeachment contracts on Polymarket
Polymarket typically offers several impeachment-related contracts with distinct resolution criteria:
- Will Trump be impeached by the House? This contract resolves Yes if the House of Representatives passes at least one article of impeachment. Note that Trump has already been impeached twice (2019 and 2021), so this contract applies to any future impeachment during his current term.
- Will Trump be convicted by the Senate? A separate and more consequential contract. Senate conviction requires a two-thirds supermajority (67 votes), making it a much higher bar than House impeachment.
- Will Trump leave office before January 2029? A broader contract covering impeachment, resignation, incapacitation, or any other scenario where Trump does not complete his term.
Each contract type has very different implied probabilities and trading dynamics. The House impeachment contract typically trades at a higher probability than the Senate conviction contract due to the different vote thresholds required.
How impeachment works (for traders)
Understanding the constitutional process is essential for trading these contracts:
House impeachment: A simple majority (218 votes) in the House is sufficient to impeach. The House Judiciary Committee typically drafts articles of impeachment, which then go to the full House for a vote.
Senate trial: After House impeachment, the Senate conducts a trial. Conviction requires 67 of 100 senators to vote guilty. No president has ever been convicted by the Senate.
Political math: With the current partisan composition of Congress, impeachment by the House requires either opposition party control or significant cross-party support. Conviction by the Senate requires 16+ senators from the President's party to vote guilty, assuming the opposing party votes unanimously for conviction.
What current odds mean
Impeachment contract prices on Polymarket reflect the market's assessment of political dynamics:
House impeachment odds fluctuate based on which party controls the House, the severity of perceived presidential misconduct, and the political calculus of House leadership. Historically, these contracts have traded in the 5-20% range during the current term.
Senate conviction odds consistently trade at much lower levels, typically below 5%. The two-thirds requirement makes conviction extremely difficult absent an extraordinary political realignment.
Prices spike on specific events, including legal developments, congressional investigations, or major political scandals. These spikes often partially reverse as traders assess the durability of the catalyst. For more on Trump-related markets, see our Polymarket Trump overview.
Trading impeachment contracts
Impeachment markets have distinctive trading characteristics:
News-driven volatility: Major news events, particularly legal rulings, congressional hearings, or investigative reporting, cause rapid price swings. Set up news alerts and be prepared to act quickly. Use Polymarket trading strategies for event-driven approaches.
Partisan overpricing: Impeachment contracts are susceptible to wishful-thinking bets. Traders who strongly oppose or support the President may buy Yes or No based on preference rather than probability. This creates mispricings that more analytical traders can exploit.
Conditional logic: Consider related markets. If the opposition party is favored to win the House in midterms, impeachment odds should logically increase. If House control markets move but impeachment markets do not adjust, there may be an opportunity.
Historical base rates: Four US presidents have faced formal impeachment proceedings in nearly 250 years. The base rate is low. Senate conviction has a base rate of zero. Weight these historical frequencies when assessing whether contract prices are reasonable.
Resolution criteria details
Pay close attention to the specific contract you are trading:
- Impeachment vs. conviction: These are entirely different contracts with different resolution criteria. Buying Yes on impeachment does not mean you are betting on removal from office.
- Time windows: Some contracts specify a deadline (e.g., "impeached before December 31, 2027"), while others cover the entire presidential term.
- Resolution source: Official congressional records typically serve as the resolution authority.
Historical context
Trump's prior impeachments provide context for current markets. The first impeachment (December 2019) resulted in Senate acquittal along largely party lines. The second impeachment (January 2021) also resulted in acquittal, though seven Republican senators voted for conviction. These precedents inform how traders assess the probability of future proceedings.
