This is a highly niche and conditional political market. It speculates not just on an election winner, but on an election that is itself contingent on the outcome of another event (the Presidential election). For a global audience, a by-election in Galway West is extremely obscure.

April 27, 2026 - April 30, 2026, due to indiscriminate speculative capital inflows, multiple candidates (e.g., Seán Kyne, Míde Nic Fhionnlaoich, Niall Murphy) saw their prices abnormally surge by 10c to 23c, pushing the total implied probability sum well over 100% and reflecting extreme market irrationality. April 13, 2026 - April 15, 2026, Noel Thomas's price dropped from 70.5c to 56c as the market began to correct his overvaluation following a previous irrational surge. April 13, 2026 - April 15, 2026, Mark Lohan's price rose from 3.7c to 9.45c as the market re-evaluated his potential as a left-wing candidate to contest the vacant seat. April 14, 2026 - April 15, 2026, Helen Ogbu's price surged from 1c to 8.35c, likely due to favorable polling or electoral analysis prompting capital inflows. March 30, 2026 - March 31, 2026, Noel Thomas's price plunged from 51c to 38c as the market initiated a belated correction on his extreme overvaluation, increasing selling pressure. March 29, 2026 - March 30, 2026, Niall Murphy's price surged from 3.75c to 20.6c due to speculative retail capital flowing into low-priced options searching for unpriced dark horses. March 28, 2026 - March 30, 2026, Seán Kyne's price surged from 7c to 21.5c (and further to 25.5c) as the market corrected its massive historical undervaluation of the strong Fine Gael candidate. March 12, 2026 - March 15, 2026, Sheila Garrity's price rose from 11c to 16.3c as the market re-evaluated her potential to inherit Catherine Connolly's vote base. February 24, 2026 - February 26, 2026, Noel Thomas's price dropped from 52c to 41c, and Seán Kyne from 50c to 38c, serving as a correction from an earlier period of extreme overvaluation (aggregate sum > 400%).

There is a severe logical divergence in the market. Since this is a single-seat by-election with only one possible winner, the sum of all candidates' win probabilities must mathematically equal exactly 100% (or slightly less, accounting for fees/slippage). However, the current implied probability sum is approximately 230%, meaning market prices are completely detached from basic reality and mainstream electoral forecasting, driven primarily by blind speculative buying.
