Resolution criteria on PolyGram: This market will resolve to "Yes" if the next individual to be sworn in as President of the United States after Donald J. Trump is the listed age or older on the day on which they are sworn in. Otherwise, this market will resolve to "No". The individual's age will be calculated on the day on which they are sworn in. A person will be considered to have advanced from one age to the next immediately upon the beginning of the calendar day of their day of birth. In the event that no individual other than Donald J. Trump has been sworn in as President of the United States by March 31, 2029, 11:59 PM ET, this market will resolve to "No".

Current odds favour the NO side at 33%, making this a directional market with 805 days to resolution, giving the order book ample time to absorb new information, backed by $38K of resting liquidity.

Polymarket settles political markets from authoritative sources - Associated Press race calls for US elections, the relevant electoral commission for national votes, and the UMA optimistic oracle for contested or ambiguous resolutions. Prices you see are probabilities derived from thousands of traders deploying real capital; they update in real time as new polls, debates, endorsements and news hit the tape. PolyGram surfaces the same order book with an email-first login and USDC settlement on Polygon.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.

Political markets occasionally see longer settlement when outcomes hinge on official certification rather than the polling result itself - the proposer waits for the certifying body's announcement, which can push payout 12-48 hours past the calendar end-date. Funds clear directly to your in-app USDC balance on Polygon. Withdrawals are non-custodial: send to any address you control, typical confirmation under 30 seconds, gas paid in USDC if you'd rather not hold MATIC.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition - historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose. For "Next US president's age at inauguration?", the considerations above apply directly - Political markets are exposed to information asymmetry between insider and retail traders, and to last-minute polling shifts that can move the line 15-20¢ in the final 48 hours. Long-dated political contracts also carry meaningful time decay if the underlying race is close.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
