Polymarket Trump Impeachment Odds Depend on Congressional Control

Traders on prediction market Polymarket are pricing the likelihood of Donald Trump facing House impeachment before his term ends at approximately 68%. In contrast, the probability of this occurring before December 31, 2026, is priced at roughly 2%.

This 33-fold difference between two contracts addressing nearly the same question highlights a key insight: the market is not necessarily predicting that impeachment is inevitable, but rather pricing the calendar and congressional arithmetic independently of political sentiment.

The Contract Split: Two Clocks, One President

Polymarket’s “Will Trump be impeached before his term ends?” market resolves as “Yes” if the House passes at least one article of impeachment by a simple majority at any point before January 20, 2029.

As of its last update on August 24, 2026, this contract was trading at approximately 68%, with cumulative volume reaching about $94,463 since the market opened on March 19, 2026.

A separate contract with a shorter timeframe asks the same question but sets the deadline at December 31, 2026, prior to the newly elected House completing its committee assignments. According to Polymarket pricing cited in Washington Examiner coverage, this contract trades at a premium closer to 2%.

The same event involving the same officeholder carries vastly different implied probabilities because the two contracts are wagering on different Congresses.

Why the Math Changes After the Midterms

Republicans currently hold narrow majorities in both chambers of Congress. A GOP-controlled House has little institutional incentive to pursue articles of impeachment against a Republican president unless there is a significant fracture within the party.

This dynamic explains the 2% price: it represents a bet that the current Congress will act before its term expires, a scenario with a base rate close to zero.

The 68% figure, however, prices in the impact of the 2026 midterms. If Democrats regain control of the House, they acquire subpoena power, control over the Judiciary Committee, and the ability to schedule floor votes on their own timeline—powers not available under the current majority.

Forecasters monitoring generic ballot trends generally indicate that Democrats are favored or competitive in flipping the chamber. Polymarket’s long-dated contract effectively acts as a compounded bet: the probability of a Democratic House multiplied by the likelihood that a Democratic majority will bring articles to a vote within the roughly two-year window following the midterms.

Prediction markets have increasingly served as the fastest-moving indicator for this type of time-bound political risk. A similar dynamic was observed in Kalshi’s government shutdown odds market, where prices moved in lockstep with the legislative calendar rather than public sentiment alone.

The mechanism here is identical: traders are not voting on whether Trump deserves impeachment; they are pricing the sequence of procedural gates that must open first.

Impeachment Is Not Removal, And Markets Know It

Both Polymarket contracts resolve based solely on House passage. Neither requires a Senate trial, conviction, or removal from office to settle as “Yes.” This distinction is crucial for interpreting these odds and is grounded in constitutional mechanics rather than market convention.

According to the Congressional Research Service’s report on House impeachment procedure, the House impeaches by a simple majority vote adopting articles, which serves as a formal accusation akin to a criminal indictment.

Trump just said he will get impeached
Both major prediction markets are saying the same thing right now.
Kalshi has Democrats around 85% to take the House.
Polymarket is even higher, near 87%.

Removal is a separate Senate proceeding requiring a two-thirds vote of senators present to convict. Disqualification from future office requires only a majority vote as a distinct, additional step.

The CRS report notes that the House has impeached three presidents: Andrew Johnson in 1868, Bill Clinton in 1998, and Trump in both 2019 and 2021. In every instance, the Senate declined to convict.

A 68% price on House impeachment therefore conveys nothing about the significantly higher bar of Senate removal, which constitutes a structurally separate market question.

When the Calendar Changes the Odds, Prediction Market Kalshi Lets Traders Price the Trump And Political Path Directly

The Trump impeachment markets illustrate why political probabilities can shift dramatically without any change in underlying views of the politician involved. What changes is the path: elections, congressional control, committee power, deadlines, and the number of remaining procedural steps.

Kalshi provides traders with a way to take positions directly on these types of political outcomes.

Instead of attempting to translate a House flip, impeachment vote, or government funding fight into a stock, Bitcoin, or bond trade, users can focus on the event itself and the specific conditions required for the contract to settle.

This distinction is vital when two seemingly similar questions carry wildly different probabilities simply because one has months to resolve while the other has years.

For traders already analyzing congressional arithmetic and timing, Kalshi transforms that thesis into a dedicated market.
