April 22, 2026 - April 26, 2026: The Republican Party price dropped steadily from 30.5c to 17c. This was likely driven by market reactions to a potential primary challenge facing the incumbent or negative local polling trends, leading to a significant downgrade in expected win probability.
April 10, 2026 - April 11, 2026: The Democratic Party price plunged from 72c to 57c, while the Republican Party price surged from 30c to 44c. This sharp correction was likely driven by new critical polling data or the incumbent releasing better-than-expected fundraising reports, forcing the market to dial back its prior overconfidence in a Democratic flip.
March 5, 2026 - March 9, 2026: The Democratic Party price rose from 65c to 70.5c, signaling increased market confidence in a seat flip likely driven by negative sentiment against the incumbent, though the move did not breach the 10c alert threshold.
February 9, 2026 - February 11, 2026: The Democratic Party price drifted down from 64c to 58.5c, and the Republican Party price fell from 36.5c to 31.5c. While neither move exceeded the 10c threshold, the simultaneous decline pushed the total implied probability below 100%, indicating a liquidity gap at that time.
