The market on whether Shabana Mahmood will be the next Chancellor of the Exchequer of the UK in 2026 surged 37.7 percentage points in the past 24 hours, rising from 38.8% to 76.5%.
This significant repricing coincided with whale activity that moved in concert with the price change. Over the same period, 128 unique whales purchased $86K worth of YES contracts while selling $44K, resulting in a net whale inflow of $42K into the YES side.
The total 24-hour volume on Polymarket for this contract was $82K, close to the whale buy volume alone, indicating that larger traders drove much of the recent action. Since the market’s inception, it has seen $238K in lifetime volume across 439 unique traders, highlighting a relatively active interest in this political outcome.
The alignment between whale buying and the sharp rise in the YES price suggests that major traders collectively reassessed Mahmood’s chances, pushing the market to price in a substantially higher probability of her becoming Chancellor in 2026. This combined price and flow movement signals a strong consensus shift among large participants toward that outcome, reflecting updated information or sentiment within the prediction market.
