Prime Minister Keir Starmer is facing an earlier resignation deadline, with Polymarket odds now indicating he may step down by 29 August 2026 rather than the previous estimate of 6 September 2026. This ~8-day shift in the implied exit date has been reflected in the ~86% probability on the relevant Polymarket contract.
The change in Polymarket odds suggests growing market uncertainty over Starmer's political future, though the PM has not indicated any plans to resign. The Polymarket contract is a real-money bet on whether Starmer will have announced his resignation by the given date.
