Will Trump be impeached and removed from office?

Step 1: Establish Base Rates and Constitutional Requirements

The resolution requires BOTH House impeachment AND Senate conviction (67 votes). Historical base rate for Senate removal: 0% (no president ever removed). Trump was previously impeached twice (2019, 2021) with Senate votes of 52-48 and 57-43 for conviction—both far short of the 67-vote threshold.

Step 2: Assess Current Political Landscape (September 13, 2026)

Senate composition: 53 Republicans, 47 Democrats. Conviction requires 67 votes, meaning ~20 Republican defections would be needed—an unprecedented level of party defection in modern politics.

Key developments:

• Unauthorized Iran military engagement (since Feb 2026) causing geopolitical/economic turmoil
• Congressional non-binding votes requesting cessation: Senate 50-48, House 214-208
• Articles of impeachment filed August 24, 2026 by Rep. Al Green
• Democrats likely to win House control in Nov 2026 midterms (85% probability)

Step 3: Decompose the Probability

P(Removal) = P(House Impeachment) × P(Senate Conviction | House Impeachment)

House Impeachment:

• Current House: Republican-controlled, unlikely to impeach
• Post-midterm House (Jan 2027-Jan 2029): Democrats highly likely to control (85% probability)
• Given Iran conflict and filed articles, House impeachment probability if Dems control: ~70%
• Overall P(House Impeachment by Jan 2029): 0.85 × 0.70 ≈ 0.60

Senate Conviction Given Impeachment: This is the critical constraint. Requiring 20 Republican senators to vote for conviction represents:

• 38% of current GOP caucus defecting
• No modern precedent (max was 7 GOP senators in Trump's 2021 trial)
• Even with Iran crisis, partisan polarization remains extreme

Scenarios for 20+ GOP defections:

1. Catastrophic escalation: Iran conflict spirals into major war with thousands of U.S. casualties + clear evidence of constitutional violations → ~8% chance
2. Economic collapse: Inflation crisis + recession blamed on presidential actions → ~3% chance
3. Smoking gun evidence: Incontrovertible proof of "high crimes and misdemeanors" that fractures GOP base support → ~5% chance

Estimated P(Senate Conviction | Impeachment): ~7.5%

Step 4: Calculate Combined Probability

P(Removal) = 0.60 × 0.075 ≈ 0.045 (4.5%)

Step 5: Compare to Market Odds

Market: 16.5% My estimate: 4.5% Divergence: Market is ~3.7x higher than my estimate

The market appears to be overweighting:

• Impeachment likelihood (conflating House impeachment with full removal)
• Sentiment premium from Iran conflict and inflation shock
• Tail risk of unprecedented GOP defection

The quantitative model cited in research (3%) is close to my estimate, suggesting the market carries significant sentiment premium.

SIGNIFICANT EDGE DETECTED: Market appears overpriced by ~3.7x

Market odds: 16.5% My estimate: 4.5% Implied edge: Market overvalues removal probability by 12 percentage points

Analysis: The market is likely conflating House impeachment probability (60-70%, high) with full removal probability (4-5%, very low). The 16.5% price reflects:

1. Sentiment premium: Iran conflict + inflation creating emotional trading
2. Innumeracy on Senate math: Traders underweighting the structural impossibility of 20 GOP defections
3. Recency bias: High-profile impeachment filing (Aug 24) driving short-term demand

Value Assessment: The NO side (betting against removal) offers strong value at current 83.5% implied probability. True probability of NO resolution is likely ~95.5%.

Caveats:

• Tail risk is real but overpriced
• If Iran conflict escalates catastrophically, market could be right
• Quantitative models (3%) align with my estimate, suggesting market inefficiency rather than information I'm missing

Recommendation: Current odds favor betting NO (against removal) with expected value of ~12% edge, but position sizing should account for genuine tail risk from unprecedented geopolitical situation.
