This market will resolve according to the candidate who wins the nomination for the Democratic Party to contest the NH-01 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Democratic primary will take place on September 8, 2026. If no nominee is announced by November 3, 2026, 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official Democrat sources, including https://democrats.org/.
Prediction markets currently assign a 60% probability that Stefany Shaheen will win the Democratic primary for New Hampshire's 1st Congressional District. This price, found exclusively on Polymarket, indicates the market views her nomination as more likely than not, but with significant uncertainty remaining. The remaining 40% is split between other potential candidates and the "Other" option. It is critical to note that trading volume is extremely thin, with zero dollars in volume across the related markets, meaning these odds are highly preliminary and not backed by substantial money.
The primary factor is Stefany Shaheen's formidable political pedigree and early positioning. As the daughter of U.S. Senator Jeanne Shaheen, she carries immediate name recognition and established connections within New Hampshire's Democratic apparatus. This inherent advantage is often decisive in low-information primary elections. Secondly, the electoral calendar is a key driver. The primary is not until September 2026, over 230 days away. At this early stage, in the absence of a declared competitive field, markets naturally default to pricing the most recognizable potential candidate as the frontrunner. The lack of any declared high-profile challengers solidifies this initial assessment.
These odds are highly susceptible to change based on candidate declarations and local political developments. The most significant catalyst will be the official entry of other credible candidates into the race. A high-profile challenge from a sitting state legislator or a well-funded local activist could rapidly shift the probability away from Shaheen. Conversely, if she officially declares her candidacy and secures early endorsements from key state party figures and unions, her odds could solidify and increase. Monitoring for candidate filings and local New Hampshire political news through 2025 will be essential, as the current market reflects a default assumption rather than a contested race analysis.

This prediction market focuses on determining which candidate will secure the Democratic Party nomination for New Hampshire's 1st congressional district (NH-01) in the 2026 midterm elections. The primary election is scheduled for September 8, 2026, with the winner advancing to contest the general election for a seat in the U.S. House of Representatives. The market resolves based on official Democratic Party sources, including the Democratic National Committee's website. If no nominee is officially declared by November 3, 2026, the market resolves to 'Other.' This topic garners significant interest as NH-01 is a perennial swing district, often considered a bellwether for national political trends. Control of this seat can influence the balance of power in the House, making the primary a critical internal party battle that shapes the Democratic strategy for the 2026 election cycle. The race is closely watched by political analysts, party strategists, and investors seeking to gauge electoral momentum and candidate viability ahead of the national midterms.
New Hampshire's 1st congressional district has a long history as one of the nation's most competitive House seats, frequently switching party control. Since 2007, the district has changed partisan hands five times. Democrat Carol Shea-Porter held the seat from 2007-2011, 2013-2015, and 2017-2019, while Republican Frank Guinta held it from 2011-2013 and 2015-2017. The current incumbent, Democrat Chris Pappas, first won the seat in the 2018 Democratic wave election. He was re-elected in 2020 by a margin of 5.2 percentage points, in 2022 by 8.7 points, and in 2024 by 4.1 points, demonstrating the district's persistent volatility. The Democratic primary has historically been competitive, with Pappas himself emerging from a crowded field of eleven candidates in the 2018 primary, winning with 42% of the vote. This pattern suggests the 2026 primary could similarly attract multiple credible contenders, especially if Pappas retires. The district encompasses the eastern part of the state, including Manchester, the Seacoast region, and the Lakes Region, with demographics that include both urban centers and rural towns.
The outcome of the NH-01 Democratic primary has significant implications for the national political landscape. As a swing district, it is a key battleground in the Democratic Party's effort to maintain or expand its House majority. The nominee's ideological profile, whether moderate or progressive, will signal the party's strategic direction in competitive districts nationwide. A contentious primary could drain financial resources and create internal divisions, potentially weakening the eventual nominee for the general election. For New Hampshire voters, the primary determines who will represent the Democratic Party on critical issues like healthcare, climate policy, and economic development specific to the region. The race also serves as an early testing ground for campaign messages and voter mobilization tactics that may be deployed in other competitive 2026 races across the country.
As of late 2024, the field for the 2026 NH-01 Democratic primary remains undeclared. Incumbent Representative Chris Pappas has not publicly announced whether he will seek a fifth term. Political observers are watching for signals from potential candidates, including state legislators and local officials, who may enter the race if Pappas retires. The New Hampshire Democratic Party is in a standard pre-election cycle phase, focusing on building its voter file and fundraising apparatus for the 2026 cycle. No major endorsements or candidate committees have been formally established specifically for this primary race at this early stage.
The Democratic primary election for New Hampshire's 1st congressional district is scheduled for September 8, 2026. This is the date when registered Democrats and undeclared voters in New Hampshire will select their party's nominee for the general election.
The current U.S. Representative for New Hampshire's 1st congressional district is Democrat Chris Pappas. He was first elected in 2018 and has served since January 2019, winning re-election in 2020, 2022, and 2024.
Yes, New Hampshire allows voters registered as 'undeclared' (independent) to choose either the Democratic or Republican primary ballot on election day. This system makes independent voters a crucial demographic in determining primary outcomes.
New Hampshire primary elections operate on a plurality system, meaning the candidate with the most votes wins the nomination, even if they do not receive a majority. There is no runoff election for congressional primaries in New Hampshire.
The market resolves based on a consensus of official Democratic Party sources, primarily the Democratic National Committee website (democrats.org). The candidate officially certified as the nominee by the New Hampshire Democratic Party will be the resolution outcome.
