Market context
Wisconsin's Democratic primary for governor takes place on 11 August 2026, with the margin between the top two finishers determining settlement. The market currently shows 0% implied probability, suggesting traders expect either a decisive outcome outside the specified bracket or genuine uncertainty about whether the primary will proceed as scheduled. Given that no major Democratic candidate has formally declared for the race as of late 2024, the absence of trading activity reflects the early stage of the cycle rather than confidence in any particular outcome.
Wisconsin Democratic gubernatorial primaries have historically produced competitive races when multiple candidates enter. The 2022 primary saw Tony Evers secure the nomination with roughly 67% of the vote against lesser-known challengers, a decisive margin. However, 2018 featured a more fragmented field with several credible candidates splitting votes more evenly. The current 0% reading suggests the market lacks sufficient information to price any specific margin bracket, a common pattern when candidate fields remain undefined and campaign infrastructure has not yet mobilised.
Traders should monitor candidate announcements throughout 2025 and early 2026, particularly whether incumbent governor Tony Evers faces a primary challenge or whether the race becomes an open seat contest. Recent reporting from Wisconsin political outlets indicates Evers has not yet confirmed his 2026 intentions. The timing of major endorsements, fundraising disclosures, and polling releases will shape expectations around competitive dynamics. Settlement depends on official results from the Wisconsin Elections Commission, with the window closing 12 August 2026.

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
