Market context

The real-world event is the Democratic primary for New York’s 12th Congressional District seat, held on 23 June 2026, to select the nominee for the 2026 House midterm. Current crowd-implied probability for the unnamed contract in question sits at 1% YES, a stark divergence from Kalshi’s market, which assigns Micah Lasher a 64% chance of winning the nomination[1]. Analyst consensus from 270toWin and Ballotpedia confirms Lasher is the leading Democratic contender, while Jack Schlossberg is also on the ballot[2][3]. This 63-point gap between prediction-market implied odds and the unnamed contract’s 1% suggests either a mispriced outlier or a fundamentally different underlying assumption about nominee identity.

Historically, such extreme divergences in primary markets often precede late-entry candidates or internal party realignments, as seen in New York’s 2022 and 2024 congressional primaries where underdogs surged after initial polling. In NY-12, the primary occurs the same day as a candidate forum at Temple Emanu-El Streicker Center, where Democrats will select a nominee to replace Jewish Congressman Layla Law-Gisiko[7]. Traders should monitor post-forum announcements, FEC campaign finance filings for sudden funding spikes, and Emerson College’s latest district polling, which recently flagged a tight race in NY-10 and may reflect shifting dynamics in NY-12[9]. Any withdrawal or disqualification before November 3, 2026, 11:59 PM ET, would resolve this market to “Other”[1].

The catalysts for price movement include immediate post-primary media coverage, official Democrat source confirmations via democrats.org, and any replacement nominee declarations before election day. While the market resolves based on the initial nominee, any replacement before election day does not alter resolution[1]. With the settlement window ending 23 June 2026, the 1% probability appears disconnected from the 64% Lasher odds on Kalshi, highlighting a meaningful cross-platform odds divergence that traders must scrutinise before committing capital.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
