About This Event
In 2026 If the House member sworn in for NH-1 for the term beginning in 2027 is a member X then the market resolves to Yes. Early close condition: This market will close following the swearing in of the Representative for the seat in question. This market will close following the swearing in of the Representative for the seat in question.
Current Market Outlook
Prediction markets price a Democrat win in New Hampshire's 1st Congressional District at 88%. That is a high-confidence bet, meaning traders see this race as deeply tilted toward the blue candidate. An 88% probability implies the market expects a Republican win would require a major surprise, not just a close race.
This district has been competitive for years. Republican Chris Pappas currently holds the seat and won by 3.4 points in 2024. But Pappas is not running for this term, and the open seat changes the math entirely.
Key Factors Driving the Odds
The dominant factor is the open seat dynamic. NH-01 has a Cook PVI of even, meaning it leans neither Democratic nor Republican. But open seats in swing districts tend to favor the party that holds the national mood advantage. The 2026 midterms look like a Democratic-friendly environment given the Republican White House and Senate.
Another factor: New Hampshire's state-level Democratic infrastructure is strong. The state has a Democratic governor, a split legislature, and a history of rejecting Republican overreach in presidential years. Local party organization matters more in midterms than national coattails.
The third factor is candidate recruitment. No serious Republican challenger has emerged yet. Democrats have a deep bench in the state, including state legislators and former Pappas staffers. A weak GOP field pushes the odds higher.
What Could Change These Odds
A strong Republican recruit could shift this market to 70-75%. If former Governor Chris Sununu decides to run for the seat, the race becomes a toss-up. Sununu won statewide multiple times and would bring name recognition and fundraising.
The national environment matters too. A major economic downturn or a foreign policy crisis that boosts the president's approval could drag down Democratic chances. But those are low-probability events priced into the 12% Republican win probability.
The primary calendar is the next concrete catalyst. New Hampshire's primary is in September 2026. By summer 2026, the field will be set, and the market will adjust based on polling. If polls show a generic Democrat leading by 5+ points, 88% might even be too low.

Overview
New Hampshire's 1st congressional district (NH-01) is one of the most competitive House seats in the United States, and the 2026 election will determine who represents the district for the term beginning in January 2027. The district covers most of eastern New Hampshire, including Manchester, Rochester, and the Seacoast region, along with the Lakes Region and parts of the White Mountains. It has a history of flipping between parties, making it a bellwether for national political trends. The current representative is Republican Chris Pappas, who has held the seat since 2019, but the district's partisan lean is nearly evenly split, with a Cook Partisan Voting Index of D+1. The 2026 race will be shaped by the national political environment, candidate recruitment, and local issues like the economy, housing affordability, and healthcare. The outcome could determine control of the House, as NH-01 is one of roughly two dozen toss-up seats nationwide. The market resolves to Yes if the member sworn in for NH-01 for the term beginning in 2027 matches the specified candidate. The market closes after the swearing-in ceremony in January 2027.
Historical Context
New Hampshire's 1st congressional district was created in 1847 and has undergone multiple redistrictings. Since the 1990s, it has been a competitive swing district. From 1996 to 2006, Republican John E. Sununu held the seat, then lost a Senate race. Democrat Carol Shea-Porter held the seat from 2007 to 2011 and again from 2013 to 2015, losing to Republican Frank Guinta in 2010 and 2014. Guinta held the seat from 2011 to 2013 and 2015 to 2017, then lost to Democrat Chris Pappas in 2018. The district has flipped party control six times in the last nine elections (2006, 2010, 2012, 2014, 2016, 2018). The 2022 redistricting made the district slightly more Democratic, shifting the Cook PVI from R+1 to D+1, by moving the more Republican towns of Bedford and Londonderry into the 2nd district. In the 2024 presidential race, the district voted for Donald Trump by 2 points, while Pappas won his race by 6 points, showing ticket-splitting. The 2026 election will be the first held under the current district lines without a presidential race on the ballot, which could shift turnout dynamics.
Why It Matters
Control of the U.S. House of Representatives often hinges on a handful of competitive seats, and NH-01 is one of the most closely watched. The outcome in 2026 could determine which party holds the majority, affecting the legislative agenda on issues like taxation, healthcare, and infrastructure. New Hampshire's small population means each congressional seat carries significant weight in the 435-member House. The district's demographics are also notable: it has a high proportion of independent voters, around 40% of the electorate, who often decide elections. The NH-01 race is a test of national political trends, such as the popularity of the incumbent president, economic conditions, and voter sentiment on social issues. Local issues like the opioid crisis, housing costs, and the state's energy policy also play a role. The race attracts significant national money: in 2024, outside groups spent over $15 million on the NH-01 race, making it one of the most expensive House races in the country. The outcome will signal whether New Hampshire remains a purple state or trends toward one party.
Current Status
As of early 2025, no candidates have formally declared for the 2026 NH-01 race. Incumbent Chris Pappas has not announced whether he will seek reelection or run for higher office, such as governor or Senate. Governor Kelly Ayotte is term-limited and may run for Senate in 2026, creating a potential cascade of candidates. On the Republican side, Russell Prescott and Karoline Leavitt are seen as likely candidates, but others like former state representative Steve Negron or businessman Matt Mowers may also run. The NRCC has listed NH-01 as a top target. The Democratic Congressional Campaign Committee (DCCC) has signaled it will defend the seat. The national political environment in 2026 will depend on the approval ratings of the president and Congress, economic conditions, and major events like Supreme Court decisions or international crises. Early polling and fundraising will provide clues, but the race is expected to be highly competitive.
