For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution.

Market outcomes
| Will Trump endorse any candidate for President before 2027? | 12% YES | 89% NO |
Donald Trump faces a decision on whether to publicly endorse a candidate for the 2028 presidential election or its Republican primary before the end of 2026. The market currently prices this outcome at 13% on Polymarket's order book, reflecting trader assessment that Trump will refrain from formal endorsement during this window. The resolution hinges on explicit public statements from Trump himself or his representatives, or consensus reporting from credible news sources documenting such an endorsement.
Historical precedent suggests Trump's endorsement behaviour varies significantly by context. In 2016, Trump remained largely uncommitted until late in the primary season. During the 2022 midterms, Trump endorsed numerous candidates early and frequently, leveraging endorsements as a political tool. However, the 2028 cycle presents distinct dynamics: Trump may position himself as a potential candidate rather than kingmaker, which would create incentive to withhold endorsements that could complicate his own path. His 2024 primary dominance and subsequent influence over the Republican Party structure suggest he retains substantial leverage without formal endorsements.
Key catalysts include any formal announcement of Trump's own 2028 candidacy status, which could substantially alter his incentive structure around endorsing rivals. Primary campaign announcements from other candidates throughout 2025 and into 2026 may pressure Trump toward positioning himself relative to the field. Media coverage of Trump's private meetings with potential candidates and his public statements at rallies or on social media will provide early signals. The Republican National Convention schedule and any significant shifts in primary polling could accelerate timeline pressures on Trump to clarify his stance.
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.
The mechanics for trading "Will Trump endorse any candidate for President before 2027?" are the same as any other PolyGram political event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$26K in lifetime turnover and $11K of resting liquidity puts this market in the below the median by volume for politics contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

The market has been open for 5 months — the price has had time to stabilise as new information arrived.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
