The probability that Shabana Mahmood will be the next Chancellor of the Exchequer of the UK in 2026 surged by 54.4 percentage points over the past 24 hours, rising from 33.1% to 87.5% on Polymarket. This dramatic repricing reflects significant market optimism about Mahmood’s chances within a short timeframe.
Whale activity accompanied this price move, with net inflows of $39K into YES contracts. Whale buy volume was $77K, while sell volume totaled $38K, indicating a clear tilt toward accumulating YES positions. A total of 127 unique whales participated in trading during this period, reinforcing the alignment between large traders and the price action.
Polymarket recorded $73K in 24-hour volume for this contract, contributing to a lifetime market volume of $226K and a total of 424 unique traders engaging with the market since inception. The parallel movement of whale flow and price suggests that major participants are supporting the surge in odds rather than resisting it.
This combination of a sharp price increase and whale buying pressure signals a notable shift in market sentiment toward Mahmood’s likelihood of becoming Chancellor.
