About This Event
In 2026 If the House member sworn in for NY-4 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 are pricing a Democratic win in New York's 4th Congressional District at 87%. That is a high confidence bet, meaning traders see a Republican victory as a genuine surprise rather than a plausible outcome. The market is trading on Kalshi only, so there is no cross-platform spread to analyze.
NY-04 covers parts of Nassau County on Long Island, including communities like Garden City, Hempstead, and parts of the South Shore. This district has been a Democratic stronghold for decades. Former Representative Kathleen Rice held the seat from 2015 to 2024, winning by double digits in most cycles. The current representative, Democrat Laura Gillen, won a competitive race in 2024 against Republican Anthony D'Esposito by about 6 points.
Key Factors Driving the Odds
The 87% probability reflects three structural advantages. First, the district's partisan lean. NY-04 has a Cook PVI of D+5, meaning it votes about 5 points more Democratic than the national average. Second, Gillen is an incumbent with a strong local brand. She previously served as Hempstead town supervisor and has name recognition across the district. Third, the national environment favors Democrats in 2026. Midterm elections typically punish the president's party, and President Trump's approval ratings in New York remain below 40%.
The 2024 race was closer than historical norms. D'Esposito spent heavily and national Republicans targeted the seat. But Gillen still won by a clear margin. The market is pricing that 2024 was the ceiling for Republican performance in this district.
What Could Change These Odds
A Democratic loss would require a massive national shift. The most plausible scenario is a national Republican wave in 2026 driven by a strong economy or foreign policy successes. But that would need to overcome the district's partisan lean and Gillen's incumbency.
The primary season matters. If Gillen faces a serious primary challenge from the left, it could weaken her general election position. But no credible challenger has emerged.
The 2026 midterms are still two years away. A lot can change. But right now, the market is pricing a Democratic hold as the baseline expectation.

Overview
New York's 4th Congressional District (NY-04) covers most of Nassau County on Long Island, including the towns of Hempstead, North Hempstead, and Oyster Bay. The district has been a political battleground for decades, shifting between Democratic and Republican control depending on national and local trends. In 2026, voters in NY-04 will elect a representative for the term beginning in 2027, and the outcome will affect the balance of power in the U.S. House of Representatives. The current representative, Anthony D'Esposito, a Republican, was first elected in 2022, flipping the seat from Democratic control. He won reelection in 2024 by a narrow margin, reflecting the district's competitive nature. The 2026 race will be shaped by factors such as the national political climate, the performance of the incumbent, and local issues like taxes, infrastructure, and education.
Historical Context
NY-04 has a history of close elections. From 2014 to 2020, the seat was held by Democrat Kathleen Rice, a former Nassau County district attorney. Rice won by double digits in her first two terms, but her margins shrank to about 5 points in 2018 and 2 points in 2020, reflecting the district's rightward shift. Rice did not seek reelection in 2022, leaving an open seat. In the 2022 midterms, D'Esposito defeated Gillen 50.1% to 47.2%, a margin of about 6,000 votes. In 2024, D'Esposito won again, 49.8% to 48.5%, a margin of roughly 3,500 votes. The district's Partisan Voter Index (PVI) was rated D+5 after the 2020 redistricting cycle, but recent election results suggest it is now a toss-up. The 2026 race will be the third consecutive competitive election in the district.
Why It Matters
NY-04 is one of a handful of swing districts that will determine control of the U.S. House in 2027. With the House currently divided by a few seats, every competitive race matters. A win for Democrats would help them regain the majority, while a Republican hold would bolster their narrow advantage. Beyond the national implications, the race will test the staying power of suburban Republican gains in the Northeast. The outcome will also influence policy on issues like tax reform, infrastructure spending, and immigration, as the district's voters have mixed views on these topics. Local issues such as the condition of the Long Island Rail Road, school funding, and property taxes are also at stake.
Current Status
As of early 2025, the 2026 race is still taking shape. Anthony D'Esposito has not officially announced whether he will seek a third term, but local political observers expect he will. Laura Gillen has not declared her intentions either, but she is considered the likely Democratic nominee if she runs again. Both parties are already fundraising and building infrastructure. The national environment will be a major factor: if the 2026 midterms are a referendum on the incumbent president, that could benefit Democrats. However, local factors like the performance of the Nassau County government and state-level issues will also play a role.

How has redistricting affected NY-04?
