The market on whether John Healey will be the next Defence Secretary of the UK in 2026 fell sharply, with the YES price dropping 29.0 percentage points in 24 hours to 40.0%, down from 69.0% a day earlier. Despite the significant decline in implied probability, whale flow diverged from this price move, indicating a disconnect between large bettors and the broader market sentiment.
Polymarket recorded $6K in volume over the last 24 hours on this contract, reflecting moderate trading activity amid the price adjustment. The divergence between price and whale flow suggests that while the market repriced John Healey’s chances downward substantially, large bettors did not follow suit by reducing exposure to YES contracts accordingly.
The sharp 29.0pp drop signals a rapid reassessment of Healey’s prospects as Defence Secretary, but the whale flow divergence points to a more complex dynamic behind the move.
Overall, the combination of a steep price decline and whale flow divergence highlights the market’s recalibration of Healey’s likelihood against the backdrop of cautious or conflicting large-scale betting.
