Will Max Miller drop out of the OH-07 race by 2026?

Platform comparison

Market context

Max Miller is still an Ohio House candidate, and the market is asking whether he will formally withdraw or suspend his 2026 OH-07 campaign before the settlement deadline. He has publicly said he is staying in the race, but the contract is sensitive to any official announcement from him or his representatives, not to speculation alone.[2][4][8][14]

The 22% crowd-implied YES probability sits below the more aggressive short-term pricing seen elsewhere: Kalshi recently priced a Miller dropout market at 47% after he teased a live announcement, while another Kalshi contract on him leaving the House before the midterms was only 34%.[17] For framing, that suggests traders see a real but far from dominant chance of an exit; by contrast, the latest analyst-style read in public reporting has been mixed, with some coverage stressing he is under intense pressure and others noting he has repeatedly rejected calls to step aside.[6][8][12][15] The narrower market here is about a specific withdrawal announcement by the deadline, so the probability should not be read as a general measure of scandal risk.

The main catalysts are official statements, filing or ballot-related deadlines, and whether party leaders or Miller’s team signal any change in position. Reporting from 3–7 August said Ohio Republicans faced a deadline to replace him on the ballot, that the cut-off was 10 August for substitution, and that Miller was scheduled to make a live announcement after telling followers to expect one.[2][8][17] Coverage also noted the House Ethics Committee opened an investigation on 4 August, which may increase political pressure, while polling reported by The Hill showed Democrat Brian Poindexter ahead, making the electoral downside of staying in more visible.[6][15]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
