Will President Trump be impeached during his term?
I assess a 40% independent probability that President Trump will be impeached before Jan 20, 2029. The 2026 Supreme Court immunity ruling and political consolidation after the April 2026 assassination attempt reduce the baseline likelihood, but structural and political tail-risks keep the chance material.
Analysis
**Stage 1 — Blind analysis (ignore market prices):**
*Context and baseline.* As of June 18, 2026, Donald Trump is serving as President, having been impeached twice previously. Two features dominate the legal/political landscape: (1) a 2026 U.S. Supreme Court decision granting *broad presidential immunity from criminal prosecution* and (2) a recent assassination attempt that tends to consolidate an incumbent's base. Historically, impeachment is a political remedy; the House needs only a majority to impeach, and previous impeachments of Trump show House willingness when politically aligned.
*Arguments and weighting.* Impeachment is driven by three inputs: (A) actionable misconduct that a House majority is willing to call a "high crime or misdemeanor," (B) partisan control of the House and willingness to use impeachment for accountability or politics, and (C) anticipated political costs/benefits given public opinion and Senate follow-through. The immunity ruling strongly curtails (A) by removing the immediate threat of criminal prosecution that often catalyzes impeachment. The assassination attempt and strengthened base lower the political benefit of impeachment for moderates. The 2.6+ year time window to Jan 20, 2029 gives room for new scandals, constitutional crises (e.g., third-term maneuvering), or other triggers, but these are uncertain.
*Probabilistic synthesis.* Balancing these factors: the immunity ruling is a large, persistent negative force on the probability. However, impeachment can still occur as a political act (symbolic or pre-emptive) if the House is controlled by the opposition and a scandal or constitutional crisis emerges. Given the uncertain control of the House after the 2026 midterms and the possibility of high-impact events between now and Jan 2029, a non-negligible but not majority probability is appropriate. I place my independent probability at *40%*.
**Stage 2 — Market calibration (compare to current market prices):**
The market currently prices "Yes" at 62% (No 38%), materially higher than my independent 40% estimate. There are several plausible reasons traders might price impeachment higher than my blind assessment:
- *Traders may be giving heavy weight to political momentum.* Markets may assume the opposition will retake the House in the 2026 midterms or that internal Republican fractures will produce defections, making an impeachment majority more likely. - *Traders may expect a high-impact triggering event.* The market may be implicitly pricing in a non-trivial chance of a new scandal, documented misconduct, or a constitutional crisis (e.g., a blatant attempt to circumvent term limits) that would force the House to act despite immunity. - *Speculative and partisan flow.* Prediction markets often attract partisan money and speculative flows that can push prices away from objective fundamentals; high volume (~420k contracts) magnifies this effect. - *Overestimation of impeachment’s dependence on criminal liability.* Some traders may not fully discount the effect of the immunity ruling and therefore overweight the probability that legal exposure will force impeachment.
Is the market mispriced? On balance I think the market is *overpricing* the probability by a meaningful margin (~22 percentage points). That said, the market's higher price reflects real tail risks (unexpected revelations, constitutional crisis) that justify a material but not majority probability. If you trade against the market, you're effectively betting those tail risks are less likely than the market assumes, or that political constraints (House composition, public reaction, and the immunity ruling) will suppress impeachment drives.
**Bottom line:** My independent estimate is 40% (Yes). The market at 62% appears to be pricing in a stronger expectation of either a change in House control, a major scandal/constitutional crisis, or is influenced by partisan/speculative flow; I view that as an optimistic stance for impeachment and therefore as a probable overprice relative to fundamentals.
Arguments
For
- Arguments for Yes: A Democratic-controlled House (or a House with sufficient GOP defections) could impeach as a political remedy even if conviction is unlikely.
- Arguments for Yes: A major new scandal or evidence of constitutional overreach (e.g., attempting to stay in office past term limits, coercing other branches) could force Republicans' hands and trigger impeachment.
- Arguments for Yes: Impeachment is sometimes used symbolically and as a means of political delegitimization; previous administrations (including Trump) were impeached despite tenuous criminal prospects.
- Arguments for Yes: Public outrage generated by a dramatic event (e.g., revelations of foreign entanglements, credible evidence of incitement) could shift moderate lawmakers toward impeachment.
Against
- Arguments against Yes: The 2026 Supreme Court ruling granting broad presidential immunity significantly lowers the chance that prosecutable misconduct will be the immediate trigger for impeachment.
- Arguments against Yes: The April 2026 assassination attempt likely bolstered the President’s public sympathy and core support, reducing political appetite for removal among moderates.
- Arguments against Yes: If Republicans hold or control the House after the 2026 elections, there will be little practical path to an impeachment majority.
- Arguments against Yes: Impeachment has high political cost and can backfire; House leaders may avoid a symbolic impeachment that could energize the President’s base and harm their midterm/electoral prospects.
Key drivers
- House majority composition after the Nov 2026 elections — decisive for whether impeachment has the simple-majority pathway in the House.
- Supreme Court 2026 immunity ruling durability and scope — reduces criminal-viability triggers for impeachment and affects political incentives.
- Emergence of new, concrete evidence of misconduct or constitutional violations not covered by immunity (classified disclosure, documented abuse of power, proven subversion of a vote).
- Public opinion dynamics following crises (e.g., assassination attempts, national security events) that can either consolidate or erode support for removal.
- Strategic calculations by House leadership (cost/benefit of symbolic impeachment vs. political backlash) and the anticipated Senate response.
Risk factors
- New scandal risk: an unforeseen, high-impact revelation between mid-2026 and Jan 2029 could substantially raise impeachment likelihood.
- Electoral risk: if the opposition controls the House after 2026, the baseline impeachment risk increases materially.
- Judicial reversal risk: the Supreme Court immunity ruling could be narrowed or reversed later, reopening criminal avenues that catalyze impeachment.
- Political realignment risk: fractures within the President’s coalition (e.g., major GOP defections) could enable cross-party impeachment votes.
- Market/flow risk: the prediction market price may reflect concentrated partisan bets rather than broad, diversified information — causing over- or under-pricing.
Scenarios
Best case
For the 'Yes' outcome: A combination of (1) the opposition winning a House majority in Nov 2026, (2) a high-impact, verifiable scandal or documented constitutional overreach by the President in 2027, and (3) sufficient moderate Republican defections to clear a House majority. In this scenario, House impeachment occurs — possibly in late 2027 or 2028 — even if the Senate ultimately acquits, because the House moves on political and reputational grounds.
Most likely
A mixed outcome where the probability of impeachment rises and falls with elections and events: either (A) the House pursues a symbolic impeachment late in the window if they secure control and a scandal appears (resulting in an impeachment vote but likely Senate acquittal), or (B) no impeachment occurs because the immunity ruling plus political calculus prevent the House from acting. The single most likely path is a late, politically motivated House action contingent on midterm results and event-driven triggers, but more likely it will not occur — hence my 40% estimate.
Worst case
For the 'No' outcome: The immunity ruling remains intact or is reinforced; Republicans retain House control (or Democratic control is weak/danger-averse); no major new revelations emerge; and public sentiment remains at least neutral or supportive. Under these conditions, impeachment does not reach the House floor before Jan 20, 2029.
