Incumbent Democrat Greg Landsman holds a commanding lead in trader assessments for Ohio's 1st congressional district due to his established name recognition, substantial fundraising edge exceeding $4.6 million raised with $3.6 million cash on hand, and the seat's underlying Democratic tilt even after 2025 redistricting. Republican challenger Eric Conroy, a former CIA officer who secured his party's nomination in the May 5 primary, trails amid more limited resources and a single recent poll showing a narrow Landsman advantage. Policy contrasts center on tax relief proposals and education funding as early in-person voting began October 6 ahead of the November 3 general election. Forecasters rate the contest Lean or Likely Democratic, consistent with the market's implied probabilities reflecting Landsman's structural position in this Southwest Ohio district.
