Will Trump be impeached and removed from office?

**Stage 1 — Blind analysis (ignore market price):**

Impeachment by the House and *removal by the Senate* are constitutionally distinct. Removal requires a two‑thirds Senate vote (67/100), which is a very high bar and has no modern precedent. Historically, Presidents have been impeached but not removed; Nixon resigned before likely removal. Removing an incumbent requires not only proof of high crimes/misdemeanors but also a sustained political calculus in which a substantial number of senators from the President’s party are willing to vote to convict.

Key points that feed my independent probability:

- *Mechanics:* P(remove) = P(House impeaches) × P(Senate convicts | impeachment). Each multiplicative term is nontrivial and time‑dependent over the ~3.5 year window to Jan 20, 2029. - *P(House impeaches):* Over the next ~3½ years there are multiple paths to a House impeachment (new evidence, criminal indictments, violent/excessive action that unites opposition, or a House partisan flip after 2026). Given plausible midterm dynamics and the willingness of opposition parties to use impeachment as a political tool, I estimate the probability the House will pass at least one article of impeachment in that window at roughly 20–40%. My point estimate for the House impeaches term is ~30%. - *P(Senate convicts | impeachment):* Conviction needs 67 votes. In nearly all plausible Senate compositions over this window, the President’s party will have enough senators to block conviction unless there is a massive and obvious bipartisan breach of norms (e.g., clearly provable, public acts that shock their party’s senators or an existential constitutional crisis). Historically, party loyalty and the high political cost of removing a president make defections rare. I therefore estimate the conditional chance of conviction given impeachment at around 15% in the event of an impeachment produced by overwhelming bipartisan evidence, but much lower (~2–5%) if impeachment is partisan. Averaging across impeachment pathways, I put the conditional conviction probability at ~15% × (how often impeachment would be bipartisan) + 3% × (how often it is partisan) — leading to a blended conditional conviction probability of ~15% × 0.3 + 3% × 0.7 ≈ 6%.

Combining the two estimates: P(remove) ≈ 30% × 6% ≈ 1.8%. I adjust that upward for tail‑risk possibilities (rapid legal developments, catastrophic events, shifts in Senate composition) and for the fact the timeframe is relatively long, giving more opportunities for dramatic catalysts. After accounting for tail events and uncertainty, I round to a *conservative independent probability of 5%* that removal (impeachment + conviction) happens before the term ends.

In short: impeachment by the House is plausible; removal by the Senate is highly unlikely but not impossible. The final independent estimate: **5%**.

**Stage 2 — Market calibration (look at current market price Yes: 0.18 / No: 0.82):**

The market is pricing a ~18% chance of impeachment + removal, more than three times my independent estimate. Reasons the market might be above my figure:

- *Conflation and headline risk:* Many traders conflate “impeachment” (much more plausible) with “removal” and price the combined event as if Senate removal were only modestly harder than House impeachment. - *Recency and tail‑risk bias:* The market may overweight vivid scenarios (major scandal, violent incident) even if their probability is low; bettors often overprice low‑probability, high‑impact events. - *Hedging and correlated positions:* Large volumes may include hedges (options, correlation trades) that push the visible Yes price higher than the pure probability implied by fundamentals. - *Information asymmetry / speculative capital:* Some large traders or political funds may be placing aggressive bets based on inside knowledge, or simply speculating, creating a persistent premium.

Why the market might be underpricing (i.e., my estimate should be higher):

- *Unforeseen catalysts:* A dramatically incriminating public event, mass resignations in the administration, or an unambiguous criminal conviction of the President could force GOP senators to defect in numbers sufficient for conviction — events whose probabilities are hard to quantify and could justify a higher number.

Bottom line on calibration: the market at 18% looks *significantly* richer than my independent model (5%). I read the gap as either (a) the market overstating conviction prospects because participants are focused on impeachment headlines or overweighting tail risk, or (b) the market placing higher odds on a rare but extreme bipartisan collapse of party discipline than I do. Given historical precedent and the two‑thirds threshold, I believe the market is mispriced toward too high a probability of Senate removal.
