2026-05-12 to 2026-05-14, Ed Gallrein's price surged from 29.1c to a peak of 53.2c before retreating to roughly 35.3c, while Thomas Massie's price plunged from 70.5c to 43.5c before rebounding to 65.5c. The reason is a Quantus Insights poll released on May 13 showing Gallrein briefly overtaking Massie, driven by Donald Trump's aggressive endorsement and super PAC ad spending, though the market subsequently repriced the incumbent's fundamental baseline. 2026-03-12 to 2026-03-15, Thomas Massie's price rebounded from 59.5c to 67.5c (+8c), while Ed Gallrein dropped from 40.65c to 31.25c (-9.4c). The reason is a mean reversion; after the previous week's panic selling over Trump's endorsement, the market reassessed the structural advantages of the incumbent, leading to a price correction. 2026-03-05 to 2026-03-11, Thomas Massie's price dropped from 64c to 55c, with challenger Gallrein rising. As the primary approached, the market began repricing the impact of external funds and endorsements on Gallrein, compressing the incumbent's premium.

May 12, 2026 - May 13, 2026, Charles Booker's price crashed intraday from 86.5c to 60.5c, before rapidly rebounding to 84c the following day. This extreme volatility occurred without significant negative news, likely due to thin liquidity as expiration approaches, causing a large order to temporarily distort the order book. April 28, 2026 - April 29, 2026, all options experienced extreme volatility. Charles Booker plummeted to 48c, while Amy McGrath and all long-tail candidates spiked to around 50c. Prices rapidly reverted to normal on April 29. The reason is likely extreme liquidity depletion or a massive anomalous trade (fat-finger error), causing a temporary distortion in order books. March 14, 2026 - March 16, 2026, Charles Booker's price corrected from 84.5c to 77.5c, indicating profit-taking or sentiment correction after an over-bullish run, without significant negative news.

February 25, 2026 - February 28, 2026, long-tail candidates experienced high volatility without breaching the 10c threshold. Joel Willett rebounded from 3c to 10.8c, while Logan Forsythe crashed from 6.5c to 0.85c, indicating market confusion in pricing the 'Other' tier liquidity. February 9, 2026 - February 10, 2026, the long-tail candidates experienced a collective crash. Pamela Stevenson dropped from 20.5c to 10.5c, while Logan Forsythe and Joel Willett both fell from 20c to 11c, due to the Feb 5 poll showing negligible support for them, triggering a market correction.
