Will Trump be impeached and removed from office?

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

*Summary of how I reason to 15%:* To get from the current presidency to an outcome of "impeached and removed," two separate, difficult political events must occur: (A) a successful impeachment in the House and (B) conviction and removal in the Senate (a 2/3 majority). Historically, removal of a sitting U.S. president by conviction is essentially unprecedented; conviction requires a large bipartisan defection by senators of the President's party. Given modern polarization and the incentives of senators to protect party leaders, I assign a substantially lower probability to the Senate conviction step than to the House impeachment step.

- I estimate the chance the House initiates and passes articles of impeachment at roughly in the 25%–40% range depending on House partisan control and the emergence of new, highly damaging evidence. Reasons this is higher than zero: impeachment is primarily a partisan-majority decision and can be used as a tool of accountability or politics. - I estimate the conditional probability that the Senate convicts given House impeachment at roughly 20%–30% in a worst-case for the President (large bipartisan scandal) and much lower otherwise, because conviction requires 67 votes. Multiplying a plausible middle case (≈35% × 25%) points to ~8.75%, but allowing for tail events (very large, non‑partisan scandal, or mass defections after an extreme event) raises a reasonable upper bound to the low teens.

Balancing these considerations, I place an independent probability of **~15%** that Trump will be impeached and removed before the end of the term.

*Key qualitative drivers behind that point estimate:* the extremely high evidentiary and political bar for Senate conviction; the relative ease (compared with conviction) of House impeachment if the majority wants it; the fragility of any cross‑party coalition necessary for removal; and the presence of potential but uncertain legal and investigative tail risks that could increase the probability if they materialize.

**Stage 2 — Market calibration (look at market price and explain):**

The market currently prices Yes at 20% (No 80%). My independent 15% is somewhat lower than the market price. Possible reasons the market is higher:

- *Availability / headline risk pricing:* Traders overweight the nonzero chance of a sudden, dramatic scandal or new legal development that would create strong bipartisan pressure to convict. Markets often put extra weight on catastrophic/black‑swan political events. - *Speculation and partisan hedging:* Large volume and active traders may include participants speculating on tail outcomes or hedging other political exposures; retail and partisan bettors can push the price above a sober, structural assessment. - *Short‑term information risk:* Market participants may be pricing in inside information or private rumors about ongoing investigations or witness cooperation that the public record doesn’t yet reflect.

Why the market might underprice the event (the opposite direction): if the Senate majority is narrower or more fractious than commonly believed, or if the President’s behavior produces a shock that shakes GOP support, the true probability could be higher than 20%. However, absent clear evidence of that, the safer conclusion is that the market is modestly optimistic about a removal path.

Net calibration conclusion: the market at 20% is plausible but likely slightly optimistic relative to a careful structural-read of impeachment dynamics; I view it as ~5 percentage points overpriced relative to my 15% estimate. That gap could represent a tradable edge if you have conviction and can accept the political tail‑risk.
