NY-08 Democratic Primary Winner

Market context

New York's 8th Congressional District will hold a Democratic primary in 2026 to select the party's nominee for the House seat. The district, which encompasses parts of Brooklyn and Queens, has been a reliable Democratic stronghold in recent cycles. The primary winner will almost certainly become the general election representative, given the district's partisan lean and historical voting patterns.

The 100% implied probability reflects the near-certainty that a Democratic primary will occur. Since 1992, every cycle in this district has produced a contested or uncontested Democratic primary; the only scenario triggering "Other" resolution would be an extraordinary procedural failure or the unexpected absence of a primary altogether. Comparable New York House districts have maintained consistent primary participation rates above 95%, and there is no structural reason to expect NY-08 to deviate. The settlement window extends to June 2026, aligning with New York's typical primary calendar, which the state legislature confirmed in 2022 would remain in June for the 2026 cycle.

Traders monitoring this market programmatically should track New York State Board of Elections filings and candidate registration deadlines, typically occurring 4–6 weeks before the primary vote. The New York Democratic Party's official results announcement will serve as the binding resolution source. Key dependencies include whether the incumbent seeks re-election and the size of the candidate field; a crowded primary could delay official certification by several days. Recent reporting from local Brooklyn and Queens outlets will signal candidate intentions by early 2026, providing early indicators of primary competitiveness.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
