Resolution criteria on PolyGram: This market will resolve to "Yes" if, in the 2026 midterm elections, Republicans win a gubernatorial or US Senate election in any state that was won by Donald Trump in the the 2024 US presidential election but was not won by Donald Trump in the 2020 election. Otherwise, this market will resolve to "No". This market will resolve based on the results of all elections, including special elections, that are scheduled to occur in November 2026 as of October 31, 2026. If a required runoff for any such election could change the market’s outcome, the market will remain open until that runoff is conclusively called by this market’s resolution sources.

Current odds favour the YES side at 79%, making this a directional market with 154 days to resolution, giving the order book ample time to absorb new information, backed by $2K of resting liquidity.

Market outcomes
| Will Republicans win any Senate or Governor's Election in a Biden-Trump state? | 79% YES | 21% NO |
The 2026 midterms will test Republican performance in states that shifted toward Trump between 2020 and 2024. This market isolates a specific subset: states Trump lost in 2020 but won in 2024, where Republicans will contest Senate seats or gubernatorial races in November 2026. The crowd is pricing an 81% probability that Republicans capture at least one such seat, reflecting confidence in sustained Republican momentum in these swing-trending states.
Historical precedent suggests midterm dynamics often favour the party out of power. In 2022, Republicans gained Senate seats despite holding the presidency under Biden, though gains were modest by historical standards. States that shifted Republican between consecutive presidential cycles—Arizona, Georgia, North Carolina, Nevada—typically show stronger Republican performance in subsequent midterms. However, gubernatorial races in these states have produced mixed results; Arizona and Georgia elected Democratic governors in 2022 despite Trump's 2020 losses there, complicating straightforward extrapolation.
The settlement window closes 3 November 2026, capturing all November elections and any runoffs scheduled through that date. Key catalysts include candidate announcements in late 2025 and early 2026, which will clarify the competitive landscape in states like Arizona and Nevada where Senate seats are contested. Polymarket's order book currently reflects the 81% probability, though this will shift as primary results emerge and polling data accumulates through 2026. Traders should monitor state-level fundraising and demographic shifts, particularly in suburban areas where 2020-2024 Republican gains were concentrated.
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.

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. For "Will Republicans win any Senate or Governor's Election in a Biden-Trump state?", the considerations above apply directly — Trade size should reflect the binary nature of the payoff: even a 70% probability event resolves NO 30% of the time, so any single position can lose 100% of staked capital.
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.
