Will Trump be impeached and removed from office?
Given the active House floor debate and public pressure, impeachment by the House is plausible; however, removal via a two-thirds Senate conviction remains unlikely. My independent estimate that Trump will be both impeached and removed before his term ends is 14%.
Analysis
**Stage 1 — Blind analysis (ignore market prices):**
The available facts: the House is conducting a historic floor debate and appears positioned to vote on articles of impeachment; high-profile public demonstrations and an arrest of an active-duty officer for calling for removal have increased visibility and pressure. Removal, however, requires a Senate conviction with a two-thirds supermajority, a threshold that has never been met for a U.S. president. Historically, impeachments by the House are possible under a majority-controlled chamber motivated by political and legal claims; removals are rare because they require a large bipartisan Senate consensus.
I break the problem into two sequential events and estimate separately, then multiply: (1) P(House impeaches) and (2) P(Senate convicts | House impeaches). Based on the described House debate and partisan intensity, I estimate P(House impeaches) ≈ 55–65% (central estimate 60%). This reflects an active floor debate, organized articles, and political incentive for Democrats if they hold the majority to proceed. For the Senate, achieving 67 votes requires substantial defections from the president's party or an erosion of support among many Senators. Given entrenched partisanship, Republican defenses of Trump, and the historical rarity of conviction, I estimate P(conviction | impeachment) ≈ 20–25% (central 23%). Multiplying gives an independent P(impeached and removed) ≈ 0.60 * 0.23 = 13.8% → rounded to 14%.
Key inputs to those component estimates include: the current public and media attention (raising the chance of House action), the lack of historical precedent for removal (lowering the Senate probability), and the requirement of a two-thirds vote (a powerful structural constraint). I also give moderate weight to the time horizon — there is time left in the term for additional disclosures or political shifts that could raise conviction odds, but absent a seismic, bipartisan scandal, Senate liability remains low.
**Stage 2 — Market calibration (compare to market prices):**
The market currently prices Yes at 18% (No 82%). My independent estimate is 14%, about 4 percentage points lower than the market. Possible reasons the market is higher: - Traders may overweight the immediacy and drama of the House floor debate and recent public incidents, extrapolating near-term momentum into a greater chance of both impeachment and conviction. - Some market participants may be factoring in post-2026 developments (additional revelations, criminal indictments, or policy crises) that materially raise bipartisan pressure on Senators over the longer horizon through 2029; the market may be implicitly pricing those tail risks more aggressively than I am. - Liquidity and retail momentum: high-profile events produce flurries of directional bets that can push prices away from an analyst-implied fair probability, especially in a market with concentrated attention (the contract has notable but not huge volume ~513k).
Why my lower estimate might nevertheless be wrong (i.e., market could be right): a single decisive new disclosure or a cascade of coordinated Republican defections could rapidly lift conviction odds close to the market price. Conversely, why the market might be mispriced upward: traders tend to overweight salient, current events and underweight structural barriers like the two-thirds requirement and partisan discipline.
Trading implication: the market price at 18% is reasonably close to my independent fair value of 14%; if trading costs are low and time horizon is long, a contrarian position backing No offers modest edge protection. If one is convinced additional developments will materially shift Senate incentives, the market could be attractive for a Yes position, but you must be willing to accept low base-rate odds of Senate conviction.
Overall: I view the market as modestly overpricing removal risk relative to a structural, historical reading of Senate behavior, but not wildly so given real-world uncertainty through 2029.
Arguments
For
- The House is actively debating articles of impeachment, increasing the near-term probability of a formal impeachment vote.
- High-profile advocacy and public incidents (e.g., the arrest of a military officer calling for removal) raise visibility and political costs, increasing pressure on some legislators to act.
- Sealed or newly unsealed documents and ongoing legal processes could produce evidence that convinces bipartisan majorities in the Senate.
- Sustained media attention can shift public opinion, which in turn can shift Senators' cost–benefit calculations, especially in vulnerable seats.
- If the Democratic coalition holds and persuades one or more moderate Republicans, the margin for conviction improves versus baseline expectations.
- The long time horizon (until January 20, 2029) allows for additional revelations or political changes that could make conviction more plausible.
Against
- Removal requires a two-thirds majority in the Senate (67 votes) — a very high bar not historically met for presidents.
- Strong partisan loyalty to the president in his party reduces the likelihood of the large number of defections needed for conviction.
- Even with a House impeachment, Senate trials are political and often end in acquittal absent overwhelming, bipartisan evidence.
- Public demonstrations and high-profile speeches increase attention but can also polarize and harden partisan defenses rather than produce defections.
- Senators facing re-election or representing pro-presidential constituencies have strong incentives to avoid voting for removal.
- Procedural delays, legal maneuvering, or a narrow, partisan House impeachment can reduce the reputational pressure on Senators to convict.
Key drivers
- House majority's appetite for impeachment and cohesion among Democrats and swing Republicans
- Senate composition and party discipline — how many Senators from the president's party would defect
- New evidence or disclosures between now and the end of the term that materially shift political incentives
- Public opinion and influential institutional pressure (military or law enforcement statements, mass protest)
- Timing and cadence of proceedings — a quick, high-profile House vote vs. protracted inquiry
- Electoral calendar and 2026/2028 political dynamics that could change Senators' re-election incentives
Risk factors
- Two-thirds Senate requirement: a structural barrier that makes conviction rare
- Partisan loyalty and leadership whipping power in the Senate
- Insufficient or ambiguous evidence that persuades swing Senators to vote to convict
- Potential for backlash or political costs that deter Republican Senators from voting for removal
- Legal procedural protections or delays that forestall a timely Senate trial and reduce political momentum
- Market noise and short-term overreactions making price signals unreliable
Scenarios
Best case
A rapid House vote produces impeachment, followed by the emergence of decisive, incontrovertible new evidence or multiple bipartisan defections in the Senate that collectively reach a two-thirds majority. The Senate convicts and removes the president months before the term ends.
Most likely
The House moves forward and impeaches the president (or already does), but the Senate holds a trial and ultimately acquits because it cannot assemble the two-thirds majority; political fallout is significant but removal does not occur.
Worst case
Partisan polarization intensifies: either the House fails to pass articles or passes a narrowly partisan impeachment that the Senate overwhelmingly rejects. No conviction occurs and the president completes the term with impeachment proceedings politically moot.
