Market context
Donald Trump leaving office before 31 August 2026 would require a resignation, formal removal, death, or another permanent cessation of the presidency before the deadline; a temporary transfer of power would not qualify under the contract terms.[2][5] The market is pricing that outcome at just 1% YES, which is consistent with the basic institutional barriers: impeachment and conviction would need both chambers to act, while a voluntary resignation usually follows a severe personal or political crisis that is not visible in the current setup.[2][5]
The best historical frame is that presidential exits are rare, slow-moving events rather than normal headline noise, so a low single-digit probability is the default starting point unless there is clear evidence of a crisis escalating through the White House, congressional leadership, or a major health development.[2][5] By comparison, broader markets on Trump leaving before 2027 have generally sat in the low single digits to high single digits rather than implying an imminent exit, which suggests traders are still treating early departure as an extreme tail event rather than a near-term base case.[3][14]
The main catalysts are a formal announcement, an emergency schedule change, or credible reporting that a resignation or permanent removal is being prepared, because this market resolves immediately on an announced resignation/removal even if the effective date is later.[2] Traders should also watch the White House’s public calendar, any abrupt cancellations, and the reaction of congressional leaders, since those are the channels through which a real exit story would first gain traction in credible coverage.[1][2]

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
