Market context
The 2026 United States midterm elections will determine control of Congress. This market resolves affirmatively only if Democrats simultaneously retain at least 218 House seats and secure 49 or more Senate seats. Currently, the order book implies a 76% probability of this outcome, reflecting expectations that Democrats will either hold or gain ground in both chambers.
Historically, the party holding the presidency faces significant headwinds in midterm elections. In 2022, with Republicans in opposition, Democrats defied this pattern and gained Senate seats whilst losing the House by a modest margin. The current 76% probability suggests traders anticipate a notably stronger Democratic performance in 2026 than occurred four years prior. This would require not merely holding House losses to manageable levels but potentially reversing them—a rare occurrence for any party in power during a midterm cycle.
Key variables shaping market pricing include economic conditions through 2026, particularly inflation and employment data, alongside approval ratings for the sitting administration. Congressional redistricting effects from the 2020 census will remain fixed. Traders should monitor special election results in 2024 and 2025 as leading indicators of midterm momentum, as well as any significant legislative achievements or failures that reshape the political landscape. The Federal Reserve's monetary policy trajectory and broader macroeconomic forecasts will likely drive material repricing as the election approaches.

How active is this market?
$42K in lifetime turnover and $16K 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.
Last 24 hours alone saw $232 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for 4 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.

- 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

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.
