Bennett Unseated Kean by Nearly 16 Points, the Result the NJ-7 Market Had Priced as Likely Since Early October

Democrat Rebecca Bennett unseated Rep. Tom Kean Jr. in New Jersey's 7th Congressional District on November 3, 2026, winning by nearly 16 points in the unofficial count and taking back a seat Republicans had held since Kean won it in 2022. The Associated Press called the race for Bennett on election night, News 12 New Jersey and NJBIZ reported, and CBS News projected that Bennett had ousted Kean in a report updated at 11:59 p.m. that night.

As of 9:55 a.m. Eastern on November 5, 2026, the unofficial count that NBC News publishes from Associated Press data had Bennett, a former Navy helicopter pilot running for her first public office, at 186,879 votes, or 57.1%, and Kean at 135,392, or 41.4%, with an estimated 94.6% of the expected vote counted. The independent Seamus Patrick O'Toole had 5,023. The district cast 327,294 votes in that count, the most of any of New Jersey's 12 House districts, which fits a race both national parties treated as one of the most important in the state.

The NJ-7 market had priced this outcome for weeks. On November 2, 2026, Kalshi and Polymarket each had a Democratic win of the 7th District at 95%, with the Republican side at 5% on Kalshi and 6% on Polymarket. Both venues had the Democratic side at 91% on October 9 and 93% on October 19. By November 5, 2026, both quoted the Democratic side at 100% and the Republican side at 0%, and the board lists both outcomes as resolved. The result means the market's confidence in Bennett, which ran well ahead of the district's recent history, was the better reading of the race.

What the NJ-7 market priced, and why

The 7th District is not a seat that votes one way by habit. Kean took it from the Democratic incumbent, Tom Malinowski, in 2022, which CBS News noted was the second time the district had flipped since the 2018 election, and he held it in 2024. A market that put a Democratic challenger at 91% five weeks before the vote was making a strong claim about a swing seat, and the race's dated record shows what it was reading.

The first part was Kean's year. CBS News reported that the two-term congressman missed months of votes earlier in 2026 while he was being treated for depression, and that he did not disclose the diagnosis or his hospitalization until he returned to Washington in late June. The second was money. Bennett raised about 3.9 million dollars from July through September against less than 1 million for Kean, according to their third-quarter filings as CBS News summarized them, and nearly 8.2 million dollars over the whole campaign against Kean's nearly 5.9 million. The third was the national party's own triage: weeks before the election the Congressional Leadership Fund, the super PAC allied with House Speaker Mike Johnson, moved resources away from Kean's race to other contests, CBS News reported. The race was national in another way too: since August, both Johnson and House Minority Leader Hakeem Jeffries had campaigned in the district with their party's candidate, a sign of how much both sides thought the seat could matter to control of the House.

Each of those facts reached the board before November 3. The Democratic price climbed from 91% on October 9, 2026 to 93% on October 19 and 95% on November 2, on both venues each time, which means the market read each new piece of the record as confirming what it already believed rather than as a surprise. The Republican side's best price on November 2 was 5% on Kalshi, a price at which the market saw Kean keeping the seat about one time in twenty.

The margin against the price

A 95% price is a statement about who wins, not by how much, and that is the strongest reason not to read the result as the market having called the margin. Bennett would have made the November 2 price look right with a one-point win; the price did not say the race would be a rout, and no contract on this board paid more for a wide result than a narrow one. A reader who doubts the market's judgment can fairly point out that the board was at 91% when the race's most visible public indicators, the district's two Kean wins and its swing history, said less.

The margin still says something about the market's read. A 15.7-point lead in a district that flipped twice in four elections is not a coin-flip result that happened to land Democratic; it is consistent with a race whose fundamentals had shifted decisively, which is what a price in the 90s says. The volume shows how firmly that view was held. By November 5, 2026, Kalshi had traded 151,799 contracts on the Democratic side and 129,650 on the Republican side, and Polymarket's two sides had drawn $33.5K and $33.1K. The Republican contracts were cheap, which is why so many traded, and both venues had them at 0% on November 5.

The two venues also agreed with each other the whole way. On every date above, Kalshi and Polymarket had the Democratic side within a point of each other, which means the price was not one book's view but a shared one. Earlier coverage of the race on this site traced that agreement through the debate, the fundraising reports and the registration counts, from the September 28 analysis of the market against the polls to the October 23 story on Kean's spending.

What it means for New Jersey's delegation

Bennett's win is one of two Republican-held New Jersey seats Democrats took on November 3, 2026. In the 2nd District, Rep. Jeff Van Drew conceded to Zack Mullock on election night, though the AP had not called that race as of November 5. If Mullock's lead holds, the state's House delegation goes to 11 Democrats and one Republican, Rep. Chris Smith of the 4th District, the New Jersey Globe reported. Smith's own seat was never close on the board: Kalshi and Polymarket each had a Republican hold of the 4th District at 96% on November 2, 2026. The AP called the other ten districts for nine Democrats and for Smith, NJBIZ reported, so the 7th and, if the count holds, the 2nd are the only seats that changed hands.

What happens next

The count is not finished. The New Jersey Division of Elections says a mail-in ballot counts if it was postmarked by 8:00 p.m. on Election Day and reaches the county board of elections within six days, so ballots will keep arriving through November 9, 2026, and the totals above will move. The division had not posted official 2026 general-election results on the morning of November 5, and the totals become official only when the state certifies them.

The contract itself is written on whether the House member sworn in for the 7th District for the term beginning in 2027 is a Democrat. The swearing-in of the new Congress is the event that matches the contract's wording; the AP's call and the 51,487-vote lead are why both venues have treated the question as answered since election night. The next dated beat is November 9, 2026, the last day for mail-in ballots to arrive. The district's board, contract rules and full price history are on the New Jersey 7th District market page, and every New Jersey race board is on the elections hub.
