Fair Value Reasoning:
The market is undergoing a sharp correction, validating previous analysis that Doucet was severely undervalued. Aulas's price plunged from 90c to 77c in just three days, while Doucet doubled to over 22c, indicating the market is finally pricing in the complexities of the 'PLM' (Paris-Lyon-Marseille) voting system. Under this system, Aulas's fame does not guarantee a city council majority, while incumbent Doucet benefits from a strong structural base within the Left alliance (NFP/Greens). While Aulas remains the favorite due to centrist consolidation, 77c still includes a significant 'celebrity premium.' Fair value suggests a much tighter race, closer to 65/35, rather than the 77/23 currently implied.

Movers
March 11, 2026 - March 14, 2026, Jean-Michel Aulas's price plummeted from 90.5c to 77c, while Grégory Doucet surged from 9.5c to 22.6c. The reason is a drastic market reassessment of structural election risks; investors realized the previous 'inevitability' pricing for Aulas (>90%) was overly optimistic and began covering short positions on incumbent Doucet, returning his price to a more realistic competitive level. March 1, 2026 - March 6, 2026, The market entered a consolidation phase, with Jean-Michel Aulas stabilizing in the 89c-91c range and Grégory Doucet fluctuating narrowly between 8c and 10c. This indicates a temporary consensus following the late February correction, with no single option moving more than 10c. February 20, 2026 - February 21, 2026, Grégory Doucet's price surged from 4.3c to 8.8c (before settling at 7.2c), while Jean-Michel Aulas retraced from 95c to 91.5c. This volatility likely represents a market correction of the previous extreme pricing (which implied the incumbent had only a 4% chance), rather than a reaction to specific breaking news, reflecting a rebalancing of long positions.
Divergence
Despite the price correction, significant divergence remains. The prediction market implies a 77% win probability for Aulas, still treating him as an overwhelming favorite. However, mainstream political analysis typically views the Lyon mayoral election as a competitive battle, especially given the Left's traditional strength in urban centers and the three-round nature of French municipal elections. Traditional polling models would likely suggest a gap of 10-15 points between an incumbent and a strong challenger, rather than the massive 55-point spread (77 vs 22) currently shown by the market.
