Ohio markets to use your bonus on
Polymarket covers Ohio in more depth than most states:
- Ohio Senate winner: Brown or Husted.
- Margin of victory: trade on how close the race finishes.
- Mahoning County winner: a county-level market in the Youngstown area, with Brown priced at 82% there in late October.
- Senate combos: Ohio paired with races such as Iowa, Maine, Michigan and Texas.
- Ohio governor: Amy Acton (D) vs Vivek Ramaswamy (R).
How Polymarket's Ohio market resolves
The market resolves when the Associated Press, Fox News and NBC all call the race for the same candidate. If they don't agree, it waits for official certification. That matters if the race is close, because your payout could take longer than election night.
Ohio race background
Husted (R) was appointed to the seat in January 2025 after JD Vance became vice president, and has President Trump's endorsement. Brown (D) served three terms in Ohio's other Senate seat before losing in 2024. Brown leads in polling averages and fundraising, while outside spending has favored Husted.
