The probability that Shabana Mahmood will be the next Chancellor of the Exchequer of the UK in 2026 jumped 30.4 percentage points in 24 hours to 87.8%, up from 57.4% a day earlier. This sharp repricing was accompanied by significant whale activity, with net inflows of $48K into YES contracts over the same period.
Whale buy volume reached $96K, nearly double the $47K in sell volume, indicating strong buying pressure among large traders. In total, 118 unique whales participated in the market during the 24-hour window, which saw $86K in Polymarket volume. The lifetime market volume stands at $256K, with 451 unique traders involved since inception.
The alignment of whale flow with the price move underscores a consensus shift rather than a divergence between large traders and market prices. This coordinated activity pushed the market odds sharply higher, signaling increased confidence in Mahmood’s chances as Chancellor.
The combined price surge and whale buying suggest growing conviction among significant market participants, reinforcing the market’s reassessment of Mahmood’s prospects for 2026.
