Monitored by Woofun AI, three sophisticated investors have allocated a combined $25.6k on Polymarket to the proposition that UK Prime Minister Starmer will resign by June 30, 2026. These traders, exhibiting historical win rates between 80% and 82% in political markets, have pushed the average buying probability to 70.7%, while the current 'yes' odds rest at 64.5%.

Notably, wallet 0x8c57f67a committed $15.1k, a figure representing 37.7 times the median historical investment for similar stakes.

This surge in bearish sentiment regarding Starmer's tenure follows Andy Burnham's decisive victory in the Makerfield by-election on June 19, where he secured 55% of the vote. This result positions Burnham to challenge for the Labour leadership, intensifying internal party friction. Reports indicate that approximately 200 Labour MPs may back Burnham, with Cabinet loyalists reportedly demanding a resignation timeline from Starmer, who has affirmed his willingness to contest leadership while cautioning against internal discord.
