The market on whether Shabana Mahmood will be the next Chancellor of the Exchequer of the UK in 2026 saw a dramatic repricing over the last 24 hours, with the YES contract soaring 72.3 percentage points from 14.6% to 86.9% as of July 15.
This surge coincided with significant whale activity, where net flow into YES totaled $42K, supported by $82K in whale buy volume against $40K in whale sell volume. The alignment of whale flow with the price move confirms that large traders were active participants in the rally rather than opposing it.
Overall, the Polymarket 24-hour volume on this contract matched whale buy volume at $82K, contributing to a lifetime market volume of $206K and involving 385 unique traders in total. The presence of 137 unique whale wallets trading in the last day highlights broad engagement among high-value participants.
The combination of a 72.3 pp increase in the YES price and strong whale buying flow signals a rapid market consensus shift in favor of Mahmood’s chances. This coordinated price and flow dynamic indicates growing conviction among large traders alongside the broader market, marking a significant turning point in this political betting question.
