Opened · Settles

Resolution criteria on PolyGram: The 2026 U.S. general elections for Congress are scheduled to be held on November 3, 2026.

Market context

The 2026 midterm elections will determine which Republican House members seek reelection to their seats. This market resolves based on the total count of GOP representatives who announce retirement, decline to run for their current seat, or pursue different elected offices instead. The settlement window closes on 31 August 2026, allowing roughly three months after the November election for final tallies and any disputed cases to be resolved.

Historical precedent suggests Republican retirements vary significantly by cycle. In 2022, approximately 26 Republican House members did not seek reelection, whilst in 2018 the figure was around 24. Retirements typically correlate with seat competitiveness, scandal exposure, and broader party dynamics. The current 1% implied probability on Polymarket's order book reflects market consensus that retirements will fall well below any meaningful threshold—suggesting traders expect either very few departures or that the market is pricing in substantial uncertainty about what constitutes the baseline expectation for a typical cycle.

Traders should monitor official announcements from Republican members throughout 2025 and early 2026, as the filing deadline for the general election typically falls in summer 2026. Leadership changes, redistricting outcomes, and primary challenges often trigger retirement decisions. Recent reporting from Roll Call and The Hill has tracked early retirement signals, though most members delay formal announcements until late in the cycle. The resolution hinges on precise counting methodology and whether borderline cases—such as members who lose primaries—fall within the market's definition of "not seeking reelection."

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 "How many Republican House members not running in 2026?" 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.

  1. Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
  2. Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
  3. 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.
  4. 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.
  5. 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.
  6. 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?

$56K in lifetime turnover and $30K of resting liquidity puts this market in the below the median by volume for politics contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.

Last 24 hours alone saw $183 in turnover, consistent with the market's lifetime daily-average pace.

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.
