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.

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%).

The market implied probabilities diverge severely from basic logic and political fundamentals. The aggregate probability of all candidates remains at 154%, violating the basic mathematical reality of a single-seat election (which must sum to 100%). Furthermore, the sudden surge of candidates like Niall Murphy to over 20% without broad political backing contradicts mainstream electoral consensus and polling logic. This indicates the market is currently distorted by speculative trading rather than reflecting genuine political fundamentals.
