Trump out as President before 2027?

Platform comparison

Market context

Donald Trump faces a real-world risk of resigning or being removed from the presidency before the end of 2026, a scenario the crowd currently prices at just 10% on Polymarket, compared to 9% on the same platform and a notably higher 28.7% on Kalshi for impeachment and removal specifically. This divergence highlights how platforms differ: Polymarket and Smarkets trade in implied probability with lower fees but stricter KYC, while Kalshi uses decimal odds, charges higher commissions, and requires US residency, leading to materially different risk signals on the same event.

Historically, removal has been rare; Trump was impeached twice in his first term but never removed, and no US president has resigned since Nixon in 1974, framing the current 10% probability as a cautious but not implausible bet. Comparable cases show that even with strong impeachment inquiries, Senate majorities often block removal, as seen when Republicans retained control in 2021 and 2024, making the current odds a reflection of political inertia rather than imminent collapse.

Traders should watch for announcements of impeachment inquiries, shifts in Senate composition, and any invocation of the 25th Amendment, particularly if the Vice President and Cabinet act to invoke it. Recent reporting from Newsweek notes that impeachment probability has surged to record highs for Trump’s second term, suggesting that political pressure is intensifying, though actual removal remains contingent on Senate votes and constitutional thresholds that are unlikely to be met before December 2026 without a major political shift.
