This market tracks the probability that President Donald Trump will face impeachment through a House vote before the end of 2026. Across Polymarket, Predict, and Kalshi, the aggregated consensus shows a 62.0% probability of impeachment occurring within the specified window, with a 25.0% probability assigned to impeachment occurring by March 1, 2027. Resolution will be determined by official federal government records and credible reporting, requiring only a House majority vote to approve articles of impeachment—conviction or removal from office is not necessary. Watch the December 31, 2026 deadline, which marks the end of the primary resolution window for this market.
This market will resolve to “Yes“ if the US House of Representatives by simple majority vote to approve or pass one or more articles of impeachment of President Donald Trump, between July 24, 2025, and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Neither trial nor conviction by the US Senate, nor removal from office, is necessary to resolve this market to “Yes“. The primary resolution source for this market will be information from the federal government of the United States, however a consensus of credible reporting will be used.
The market resolves to Yes if the President of the United States is impeached before January 20, 2029. Impeachment occurs when an impeachment resolution passes against the President while they hold office. The event is structured across multiple checkpoint dates (June 1, 2026; September 1, 2026; January 1, 2027; March 1, 2027; and January 1, 2028), with resolution to Yes triggered if impeachment occurs before any of these dates. The critical requirement is that the President must hold the office at the time the impeachment resolution passes; impeachment of a former president or someone not currently serving would not satisfy the criteria. The market ultimately resolves based on whether impeachment has occurred at any point before the final deadline of January 20, 2029.
This market will resolve to “Yes“ if the US House of Representatives by simple majority vote to approve or pass one or more articles of impeachment of President Donald Trump, between July 24, 2025, and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Neither trial nor conviction by the US Senate, nor removal from office, is necessary to resolve this market to “Yes“. The primary resolution source for this market will be information from the federal government of the United States, however a consensus of credible reporting will be used.
Prediction markets and polls measure different things. Polls capture public opinion snapshots on impeachment support, while prediction markets reflect traders' real-money bets on whether impeachment will actually occur by Dec 31, 2026. Markets incorporate insider knowledge, legislative dynamics, and forward-looking analysis that polls may miss. Prediction markets often diverge from polling because traders face financial consequences for accuracy, creating stronger incentives to forecast outcomes rather than express preferences. Comparing the two reveals whether public sentiment aligns with expert expectations of impeachment likelihood.
Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Price differences between Polymarket and Kalshi arise from distinct user bases, liquidity depths, and trading mechanics. Polymarket may attract different trader demographics or have tighter spreads, while Kalshi operates under separate fee structures and market-making rules. Regulatory environments, withdrawal policies, and platform credibility also influence how traders price identical outcomes. These gaps create arbitrage opportunities and reflect varying confidence levels across communities. Monitoring both venues helps identify which platform's consensus carries more conviction on Trump impeachment by Dec 31, 2026.
Key catalysts include major legal developments, congressional investigations, and shifts in House party control following elections. Scandals, indictments, or high-profile testimony could accelerate impeachment momentum, while political realignment or unified party support could reduce likelihood. Changes in Trump's approval ratings, legislative priorities, and media coverage all influence trader expectations. International incidents, economic shocks, or internal GOP dynamics may also reshape the political calculus. Monitoring these signals helps predict how odds will shift as Dec 31, 2026 approaches.
