Ann Wagner, the seven-term incumbent in Missouri’s 2nd Congressional District, holds a 98% implied probability in the August 4 Republican primary because challengers Ryan Sheridan, Brandon Wilkinson, Peter Pfeifer, Elizabeth Sparks-Holmes, and Matthew Grant have not generated measurable momentum or fundraising traction ahead of the vote. Her established position within the district’s Republican electorate, combined with the absence of notable endorsements or polling shifts for opponents, has kept trader consensus locked on the frontrunner. With the primary only days away, any realistic challenge would require an unexpected late surge in turnout or a significant unforced error by Wagner, neither of which current indicators suggest is likely. The market’s pricing reflects this structural advantage in a low-profile primary setting.
