Maine Democratic Senate nominee on July 27?

Platform comparison

Market context

The real-world event is Graham Platner’s suspension of his Maine Senate campaign on 8 July 2026 after a sexual assault allegation, triggering the Maine Democratic Party’s two-week window to appoint a replacement nominee by the state-mandated 27 July deadline[1][2]. This market resolves on who the party’s apparent nominee is at 11:59 PM ET on that date, with Platner excluded unless he formally withdraws before the 13 July cutoff[1][4].

Historically, sudden nominee withdrawals in close Senate races—such as 2018’s Florida primary chaos or 2020’s New York vacancy—have seen parties convene conventions within days, often producing unexpected candidates who shift odds dramatically[1][6]. The current 1% YES probability reflects uncertainty over whether the convention will yield a consensus figure or a fractured outcome, with no established replacement procedure under Maine law[4][6].

Traders must monitor the Maine Democratic Party’s convention schedule, Charlie Dingman’s public statements as party chair, and any new endorsements from state committee members, as these will signal the likely nominee[1][4]. A recent CNN report confirms the party voted to hold a convention and that multiple Democrats have expressed interest, making the next 10 days critical for clarity[1][10]. Regulatory access remains straightforward: German GlüStV permits up to €1,500 without KYC, while US CFTC reach is limited to licensed platforms, meaning this market is accessible to non-KYC users under $1,500 thresholds without legal friction[1].

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
