Prediction Market Polymarket traders price a House impeachment of Donald Trump before his term ends at roughly 68%, against a fraction of that, around 2%, for the same outcome landing before December 31, 2026.
That 33x spread between two contracts asking a nearly identical question is the real story: it’s not a prediction that impeachment is coming, it’s a market pricing the calendar and congressional arithmetic separately from the politics.
The Contract Split: Two Clocks, One President
Polymarket’s “Will Trump be impeached before his term ends?” market resolves “Yes” if the House passes at least one article of impeachment by simple majority any time before January 20, 2029.
As of its last update on August 24, 2026, that contract was trading around 68%, on roughly $94,463 in cumulative volume since the market opened on March 19, 2026.
A separate, shorter-dated contract asks the same question but caps the window at December 31, 2026, before the newly elected House even takes its committee assignments. That contract has traded at a premium of closer to 2%, according to Polymarket pricing referenced in Washington Examiner coverage of the market.
Same event, same officeholder, wildly different implied probability, because the two contracts are betting on different Congresses.
Why the Math Changes After the Midterms
Republicans currently hold narrow majorities in both chambers, and a GOP-controlled House has no institutional incentive to advance articles of impeachment against a Republican president absent a major break within the party.
That’s the entire explanation for the 2% price: it’s a bet that this specific Congress will act before its term expires, and the base rate for that is close to zero.
The 68% figure prices in something structurally different, the 2026 midterms. If Democrats retake the House, they gain subpoena power, Judiciary Committee control, and the ability to schedule a floor vote on their own terms, none of which exists under the current majority.
Forecasters tracking generic ballot trends have generally shown Democrats favored or competitive to flip the chamber, and Polymarket’s long-dated contract is effectively a compounded bet: probability of a Democratic House multiplied by the probability that a Democratic majority actually brings articles to a vote sometime in the roughly two years of runway that follow.
Prediction markets have increasingly become the fastest-moving gauge for exactly this kind of time-bound political risk. The same dynamic played out in Kalshi’s government shutdown odds market, where prices fluctuated in lockstep with the legislative calendar rather than with sentiment alone.
The mechanism is identical here: traders aren’t voting on whether Trump deserves impeachment, they’re pricing the sequence of procedural gates that would have to open first.
Impeachment Is Not Removal, And Markets Know It
Both Polymarket contracts resolve on House passage alone. Neither requires a Senate trial, conviction, or removal from office to settle “Yes.” That distinction matters enormously for how these odds should be read, and it’s grounded directly in constitutional mechanics rather than market convention.
Per the Congressional Research Service’s report on House impeachment procedure, the House impeaches by a simple majority vote adopting articles, effectively a formal accusation, comparable to a criminal indictment.
Removal is an entirely separate Senate proceeding requiring a two-thirds vote of senators present to convict, and disqualification from future office requires only a majority vote as a distinct, additional step.
The CRS report notes the House has impeached three presidents, Andrew Johnson in 1868, Bill Clinton in 1998, and Trump himself in both 2019 and 2021, and in every case, the Senate declined to convict.
A 68% price on House impeachment therefore says nothing about the far higher bar of Senate removal, which is a structurally separate market question entirely.
When the Calendar Changes the Odds, Prediction Market Kalshi Lets Traders Price the Trump And Political Path Directly
The Trump impeachment markets show why political probabilities can swing dramatically without anyone changing their underlying view of the politician involved. What changes is the path: elections, congressional control, committee power, deadlines, and the number of procedural steps still left.
Kalshi gives traders a way to take positions directly on those kinds of political outcomes.
Rather than trying 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 exact conditions required for the contract to settle.
That distinction matters when two similar-looking questions can carry wildly different probabilities simply because one has months to resolve and the other has years.
For traders already thinking in terms of congressional arithmetic and timing, Kalshi turns that thesis into a market of its own.
