KalshiAndrew Garbarino's Long Island Seat Is Still a Republican Hold, but the Market Has Grown Less Sure in October
The New York 2nd District race in 2026 is Republican Andrew Garbarino, who has held the seat since 2021, against Democrat Patrick Halpin, and the market treats it as a Republican hold with more doubt attached than the district's record explains. Garbarino won his last two elections by more than 50,000 votes each, and all four forecasters Ballotpedia tracks rate the seat Solid, Safe or Likely Republican. What the price is saying is that the hold is the base case, but that the venues have spent October marking the Democratic side up while the ballot and the ratings stood still. Voters in parts of Nassau and Suffolk counties on Long Island settle it on November 3, 2026, both venues pay on the winner's party, and the live board above carries the current figure.
Who is on the NY-02 ballot in 2026
The field is fixed. The State Board of Elections' amended certification for the general election, dated September 17, 2026, lists Andrew R. Garbarino on the Republican and Conservative lines and Patrick Halpin on the Democratic and Working Families lines for Representative in Congress, District 2, and describes the district as part of Nassau and part of Suffolk. Each nominee carries two lines: Garbarino the Conservative line he has held in every race since 2020, by Ballotpedia's results, and Halpin the Working Families line.
Garbarino is the incumbent. The Clerk of the House's member list, published October 1, 2026, gives the 2nd District to Andrew R. Garbarino, a Republican from Bayport, elected on November 5, 2024 and sworn in on January 3, 2025, and Wikidata dates his House service in the seat to January 3, 2021. Halpin reached the ballot without a contest: Ballotpedia shows the Democratic primary canceled, with Josh Taveras, Jess Murphy, Garrett Petersen and Edwin Osorio listed as withdrawn or disqualified, and the Republican primary canceled with Garbarino unopposed.
What the NY-02 price is saying
The case for the favorite is the record, and it is long. Ballotpedia's certified results show Garbarino first winning the seat on November 3, 2020 by 23,133 votes over Jackie Gordon, then beating Gordon again on November 8, 2022 by 151,178 votes to 97,774, and beating Rob Lubin on November 5, 2024 by 202,597 to 136,371. Cook's Partisan Voter Index, as reported by Ballotpedia, rates the district R+6, and Donald Trump carried it 56.4% to 42.5% over Kamala Harris on November 5, 2024, by Ballotpedia's figures from The Downballot. That makes the 2nd a seat where the Republican member runs ahead of a presidential margin that was already wide.
The money says the same thing. Federal Election Commission figures compiled by Ballotpedia show Garbarino with $3.99M in receipts and $3.32M in cash on hand as of September 30, 2026, against $577K raised and $46K on hand for Halpin on the same date. Ballotpedia lists no public poll. Its ratings table for the October 20, 2026 update has the Cook Political Report and Inside Elections at Solid Republican, Sabato's Crystal Ball at Safe Republican and Decision Desk HQ at Likely Republican, unchanged since its July 21, 2026 update.
Against that record the price is less certain than the forecasters. Polymarket had the Republican contract at 87% on September 1, 2026 and at 86% on October 5, 2026. On October 23, 2026 Polymarket had Republicans at 80%, with Kalshi at 82%, and both venues had the Democratic contract at 20%, up from 13% on Polymarket on October 5. The market treats a seven-point move in under three weeks as worth keeping, which means it is pricing something the ratings, the money and the ballot do not show. One in five is a long way from what a Solid rating describes.
The trading sits on the cheaper side, too. As of October 23, 2026, Kalshi counted about 25,642 contracts on the Democratic outcome against about 11,361 on the Republican, and Polymarket about $12.5K on Halpin against about $8.7K on Garbarino. Those totals cover each contract's whole life, not October alone, and volume is not a forecast, but they show the Democratic side has never lacked buyers.
The case against the NY-02 read
The strongest case against the read is that the doubt is the mistake, not the record. Holders of that view would say a district Trump carried by about 14 points, an incumbent who has won three times and twice by more than 50,000 votes, a cash gap of more than seventy to one and four forecasters who have not moved since July add up to a seat that should trade well above where it does. On that view, the October move is a thinly traded contract overreacting, and a few large buyers on the Democratic side of both venues are enough to move it. A reader who holds it would point out that nothing in the district changed between October 5 and October 23, 2026, and that a price which moves without a cause tends to move back.
The record itself supports that view in a midterm. In 2022, the last election without a presidential race on the ballot, Garbarino won by 53,404 votes out of 249,032 cast, a wider share of the vote than his 2024 margin, so the smaller electorate of a midterm year has not been one that narrowed his margins.
What changes the NY-02 read
The read is wrong if Halpin wins on November 3, 2026, and the October doubt is vindicated if Garbarino's margin falls well short of the 66,226 votes he won by in 2024. Before then, these are the dated, observable things that would move it:
• Early voting, October 24 to November 1, 2026: the first ballots in the general election, and the first sign of whether turnout on Long Island resembles 2022's midterm or 2024's presidential year.
• Ratings: a move by Decision Desk HQ off Likely Republican, or by any of the other three off Solid or Safe, would give the market's doubt a public basis it does not have as of Ballotpedia's October 20, 2026 update.
• A public poll: Ballotpedia listed none as of October 23, 2026; any credible poll showing a single-digit race would explain the price, and one showing a 20-point race would undercut it.
• Late money: Halpin had $46K on hand at the end of September; outside spending on his behalf would be the clearest sign that the October move reflects more than trading.
• Election night, November 3, 2026: the Nassau and Suffolk returns, read against Garbarino's 2024 total of 202,597.
When the NY-02 market resolves
Kalshi and Polymarket settle the same question on different events. Kalshi's KXHOUSERACE-NY02-26 pair, listed on January 7, 2026, pays Yes on the Republican contract if the House member sworn in for NY-02 for the term beginning in 2027 is a member of the Republican Party, and on the Democratic contract on the same test; it is eligible for accelerated determination once a consensus of media organizations projects the winner, with an expected expiration of January 4, 2027 and a latest expiration of November 3, 2027. Polymarket's NY-02 House Election Winner market resolves on the party of the candidate who wins the seat at the November 3, 2026 election, reads party from the ballot-listed affiliation, and settles on a consensus of credible reporting. In a clean count both reach the same answer; in a contested one, Polymarket waits on reporting and Kalshi on the swearing-in.
