The market opened with the Republican's chances priced at 5% and has since declined to a current low of 2%. The most significant technical aspect of this chart is the complete lack of trading activity, with a total volume of zero contracts traded across 213 data points. This absence of volume indicates that the price shown does not reflect active trader sentiment or conviction. Instead, the price changes are likely the result of automated market maker adjustments or changes by the market's creator rather than any genuine buying or selling pressure. The recent price drop to the market's all-time low of 2% appears correlated with the outcome of the June 2 primary elections. The selection of Justin Murphy as the Republican nominee to challenge incumbent Democrat Cory Booker did not inspire confidence in the market. Instead of a positive reaction, the price fell, suggesting that the market views this specific matchup as even less favorable for a Republican win than the generic prospect was initially. Overall, the chart reflects extremely pessimistic sentiment regarding a Republican victory. The combination of a sub-5% probability and zero trading interest suggests a strong consensus that this is a highly unlikely outcome, with no speculators willing to take a position even at long-shot odds. ## Contract Snapshot The provided page content, "New Jersey Senate winner? Odds & Predictions 2026", indicates a market concerning the winner of the 2026 New Jersey Senate race. However, this excerpt does not specify the exact triggers for a YES or NO resolution, nor does it detail any key dates, deadlines, or special settlement conditions for the contract. ## Market Discussion Discussions and debates regarding "New Jersey Senate winner" encompass both the concluded 2024 election and the ongoing lead-up to the 2026 election [[^]](https://ballotpedia.org/United_States_Senate_election_in_New_Jersey,_2024). In 2024, Democrat Andy Kim's victory over Republican Curtis Bashaw was largely framed around a narrative of political change and anti-corruption, following the resignation of Senator Bob Menendez, with New Jersey being a reliably Democratic state [[^]](https://www.newsday.com/news/nation/election-2024-new-jersey-senate-kim-bashaw-p60765). Looking ahead to the 2026 Senate race, while incumbent Democratic Senator Cory Booker is overwhelmingly favored to retain his seat in a "deep-blue" New Jersey, significant debate and prediction market activity are focused on the crowded Republican primary as candidates vie for a nomination that is widely considered an uphill battle against Booker [[^]](https://en.wikipedia.org/wiki/2024_United_States_Senate_election_in_New_Jersey). ## Market Data | Contract | Yes Bid | Yes Ask | Last Price | Volume | Open Interest | | --- | --- | --- | --- | --- | --- | | Cory Booker | 97.1% | 97.8% | 97% | $10,495 | $3,315 | | Justin Murphy | 1% | 3% | 2% | $24,378 | $9,924 | ## Why is the requested research information currently unavailable?

Conversely, a Republican takeover ("NO") could be driven by the emergence of strong, well-funded Republican challengers, an unfavorable national political environment impacting Democratic candidates, or significant candidate scandals and intra-party conflicts within the Democratic Party [[^]](https://ballotpedia.org/New_Jersey_State_Senate_elections,_2027). **Key dates to watch include the primary elections in June 2027, which will solidify nominees, and ongoing candidate filing deadlines in early to mid-2027.** Throughout the year, campaign fundraising reports will provide insights into financial strength, while debates in Fall 2027 could sway undecided voters [[^]](https://ballotpedia.org/New_Jersey_State_Senate_elections). Voter registration deadlines and early voting periods in October 2027 will offer initial indications of turnout. Additionally, the full impact of the 2022 redistricting maps on district competitiveness will be tested, potentially shifting outcomes in favor of either party [[^]](https://www.njsendems.org/27/Senators). ## Key Dates & Catalysts - **Expiration:** November 03, 2027 - **Closes:** November 03, 2027 ## Decision-Flipping Events - The outcome of the New Jersey State Senate elections on November 2, 2027, where all 40 seats are contested, hinges on several key factors. - For Democrats to maintain control ("YES"), robust candidate recruitment, strong fundraising, and effective "Get Out The Vote" campaigns are crucial, especially if supported by a favorable national political environment and the popularity of incumbent senators [^] . - Conversely, a Republican takeover ("NO") could be driven by the emergence of strong, well-funded Republican challengers, an unfavorable national political environment impacting Democratic candidates, or significant candidate scandals and intra-party conflicts within the Democratic Party [^] . - Key dates to watch include the primary elections in June 2027, which will solidify nominees, and ongoing candidate filing deadlines in early to mid-2027. ## Related Research Reports - [Which party will win the U.S. House?](/markets/elections/us-elections/which-party-will-win-the-u-s-house/) - [EU loses a member before 2030?](/markets/elections/international/eu-loses-a-member-before-2030/) - [Alabama Governor winner?](/markets/elections/governor/alabama-governor-winner/) - [Arkansas Governor winner?](/markets/elections/governor/arkansas-governor-winner/) ## Historical Resolutions No historical resolution data available for this series. ## Disclaimer This content is for informational and educational purposes only and does not constitute financial, investment, legal, or trading advice.
