Market context
The real-world event is the Democratic primary for New York’s 12th Congressional District, held on 23 June 2026, to select the nominee for the 2026 House midterm. Micah Lasher is the leading candidate, with Alex Bores, George Conway, Jack Schlossberg and others also contesting. The current crowd-implied probability of 1% YES suggests the market views Lasher’s nomination as highly unlikely, despite his prominence.
Historically, low-probability primary outcomes in tight urban districts often reflect late-stage field shifts or undisclosed internal party dynamics. In comparable 2024 New York primaries, candidates with under 5% implied odds occasionally surged after endorsement announcements or withdrawal of rivals. Programmatic traders should monitor conditional order books for sudden liquidity spikes, which often precede official shifts. A trader building a bot would weight real-time donation data and local endorsement feeds more heavily than static polling.
Key catalysts include the final candidate list confirmation, any withdrawal notices before 23 June, and early endorsement waves from Democratic leaders. The NYC Board of Elections released a tentative contest list on 7 May, but changes remain possible [3]. Recent polling shows Republicans entering the midterms with a 217–212 House majority, intensifying pressure on Democratic unity [5]. Traders should watch for updates from democrats.org and FEC campaign finance filings, as sudden fundraising surges often correlate with nomination momentum [6]. Conditional orders tied to these events can capture asymmetric value if the 1% probability misprices emerging dynamics.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket App UK, which mirrors the Polymarket order book directly.
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.
