توقع: MI-13 Democratic Primary Winner

Platform comparison

Market context

The Democratic primary in Michigan’s 13th congressional district is a tight test of whether an incumbent can hold off a state-level challenger in a deep-blue Detroit seat. The market’s 18% implied probability for the current YES outcome is well below the trader pricing on major platforms, where Shri Thanedar has been shown as the favourite, with Donavan McKinney the main alternative.[2][1] That gap matters because recent polling has been narrower than the headline odds suggest: a Data for Progress survey for Justice Democrats put Thanedar only 4 points ahead, 46% to 42%, which is consistent with a race that can still move on turnout and late consolidation.[11]

The clearest historical frame is that MI-13 has already produced competitive Democratic primaries despite the district’s partisan lean, and Thanedar won the 2024 nomination with 54.9% in a multi-candidate field.[3][5] This year’s contest is materially different because the field has narrowed after disqualifications, making it more of a direct head-to-head between Thanedar and McKinney than the earlier crowded setup.[1] For traders, the main catalysts are candidate announcements, any late procedural changes to ballot access, and official primary-week scheduling, with the Democratic nominee set by the August 4 primary and the market only resolving to “Other” if no nominee is announced by November 3.[1][2]

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
