Market context
Wisconsin's 1st congressional district will elect a representative to the U.S. House in the 2026 midterm elections on 4 November. The current order book on Polymarket implies a 67% probability that the winning candidate will be affiliated with the Democratic Party, with Republican affiliation priced at the corresponding inverse. This probability reflects market participants' assessments of candidate viability, historical voting patterns, and demographic composition across the district's counties, which span from the Milwaukee suburbs through rural areas to the Wisconsin-Illinois border.
WI-01 has shifted considerably in recent cycles. The district voted for Donald Trump by 3 percentage points in 2020, yet elected Democrat Gwen Moore to the House in 2022 with 54% of the vote. Moore's personal brand and constituent service record have proven durable in a district where ticket-splitting remains evident. The 67% Democratic probability reflects this recent performance but acknowledges the district's competitive nature—neither party can assume retention without credible candidate recruitment and resource commitment.
Key variables for traders include candidate announcements from both parties, expected to intensify through 2025 and into early 2026. Moore has not yet formally declared her 2026 intentions, though she has held the seat since 2005. National political conditions, particularly economic sentiment and presidential approval ratings heading into the midterm cycle, will influence resource allocation to this district. Local Wisconsin media and the state Republican Party's candidate recruitment efforts will provide early signals about competitive intensity.

How this market resolves
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.
How to trade this market step by step
The mechanics for trading "WI-01 House Election Winner" are the same as any other PolyGram 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.
- Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
- Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
- Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.
- Size your position. If you stake 100 USDC at 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.
- Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.
- Wait for resolution. When the event resolves on-chain via the UMA optimistic oracle, the winning side settles to 100¢ automatically and USDC hits your balance within seconds. Withdrawable to any wallet you control.
How active is this market?
$929 in lifetime turnover and $3K of resting liquidity puts this market in the below the median by volume for elections contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $106 in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
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.
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.
