Victor Marx leads Republican primary polling and fundraising for Colorado governor, having raised over $1.66 million in the first four months of 2026 and built early support through his ministry work and veteran background. Traders assign him the highest probability as the June 30 primary nears, reflecting his qualification via the state assembly process that favors ideologically aligned candidates. Barbara Kirkmeyer, who petitioned onto the ballot and emphasized practical governance experience in the May 14 debate with Scott Bottoms, trails as the main alternative. Bottoms and remaining contenders show limited momentum, with no major shifts reported in the past week that would alter current market pricing ahead of the vote.
