Resolution criteria on PolyGram: This market will resolve according to the party of the candidate who wins the NJ-01 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 4, 2026. A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

New Jersey's 1st congressional district will elect a representative to the U.S. House in the 2026 midterm elections on 4 November. The current order book on Polymarket reflects a 93% probability that the seat will be won by a Democrat, with Republican chances priced at 7%. This implied probability has formed through trading activity on the platform and reflects market participants' assessment of the district's electoral leanings and candidate strength heading into the cycle.
NJ-01 has voted Democratic in recent cycles, providing historical context for the current pricing. The district backed Joe Biden by approximately 8 percentage points in 2020 and favoured Democrats in the 2022 midterms, when incumbent Donald Norcross retained the seat with 57% of the vote. Comparable Democratic-leaning districts in the Northeast have shown resilience in midterm environments, though the party holding the White House typically faces headwinds in such elections. The 93% probability reflects both the district's Democratic fundamentals and uncertainty inherent in a race still two years distant.
Traders should monitor candidate announcements and recruitment efforts from both parties, particularly whether Republicans field a competitive challenger. Changes to district boundaries through redistricting, though unlikely at this stage, could alter the electoral calculus. National political conditions—congressional approval ratings, economic sentiment, and turnout dynamics closer to November 2026—will prove material to how the current probability evolves. Early primary activity and fundraising reports in 2025 will offer concrete signals about candidate viability.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
