Market context
The Democratic Party will formally nominate a Vice Presidential candidate during the 2028 election cycle. This market resolves to YES if a specific individual is nominated and accepts that nomination, with the settlement window closing on 10 August 2028, shortly after the Democratic National Convention typically concludes. The current order book on Polymarket implies an 8% probability, reflecting substantial uncertainty about the eventual nominee's identity and whether the nomination process proceeds as historically expected.
Historical precedent suggests Vice Presidential nominations are rarely contested at modern Democratic conventions. Since 1984, sitting or designated Vice Presidential candidates have faced no serious floor challenges, with nominees typically announced before or during the convention week. The 8% probability appears to price in scenarios where the nomination process experiences material disruption—such as the presumptive Presidential nominee withdrawing late in the cycle, creating genuine competition for the running mate slot, or procedural complications delaying formal acceptance. The 2024 cycle, where Vice President Kamala Harris selected Tim Walz with limited deliberation after becoming the presumptive nominee, exemplifies how quickly modern nominations can crystallise.
Traders should monitor announcements regarding the 2028 Democratic Presidential nominee, expected in summer 2028, as this directly determines who selects the Vice Presidential candidate. The Democratic National Convention scheduling, typically held in August, will establish the formal nomination date. Any unexpected developments affecting the presumptive Presidential nominee's viability—health concerns, political reversals, or primary dynamics—could introduce genuine uncertainty into what is ordinarily a procedurally straightforward nomination process.

How active is this market?
$13K in lifetime turnover and $337K of resting liquidity puts this market in the below the median by volume for global elections contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $120 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
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.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
- CLOB
- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
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.
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.
