The market on whether Shabana Mahmood will become the next Chancellor of the Exchequer of the UK in 2026 saw a dramatic repricing over the past 24 hours, with the YES contract soaring 51.7 percentage points from 8.0% to 59.8%.
This sharp increase was confirmed by whale activity, which aligned with the price move. Whale investors bought $62K worth of YES contracts while selling $32K, resulting in a net flow of $30K into the YES side. This substantial whale net buying supports the sudden shift in market sentiment.
Market volume in the last 24 hours was $47K, slightly lower than the whale buy volume alone, indicating that whale trades dominated recent activity. Across the lifetime of the market, total volume stands at $171K, with 356 unique traders participating to date. In the past day, 123 unique whales traded this contract, highlighting significant interest from large investors.
The confluence of a 51.7pp price jump and strong whale net inflows signals a robust reassessment of Mahmood’s chances in the prediction market. The alignment of whale buying with the price surge suggests conviction behind the move rather than a speculative spike, reflecting shifting expectations about the UK’s political future as priced by Polymarket participants.
