Market context
Donald Trump is still in office, and the market’s 1% **Yes** price implies traders see only a very narrow path to a permanent departure before 31 August 2026.[1] The contract is not about a routine absence or temporary transfer of authority: it pays on resignation, removal, or any other permanent cessation of the presidency, with an announced resignation or removal counting immediately even if the effective date comes later.[1]
That is why the current pricing sits in the same broad category as other low-probability presidential exit markets: the bar is far higher than a normal news cycle shock, because impeachment would still need House action and a two-thirds Senate conviction, while a voluntary resignation usually depends on sustained political, legal, or personal pressure that is not visible in ordinary day-to-day governance.[1] In comparable departure markets, traders typically do not assign meaningful odds unless there is a concrete institutional trigger, a severe health event, or a documented collapse in support.[1]
The main catalysts to watch are any formal White House announcement, credible reporting of a medical or legal development, and the schedule around public appearances, because an explicit statement of resignation or permanent removal would resolve the market immediately.[1] Recent reporting has shown how quickly resignation odds can move when a sudden White House event is announced, even before any substantive confirmation arrives, which underlines how headline risk rather than slow-moving fundamentals tends to drive these contracts.[2]

FAQ
- 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.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
- 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.
