According to the latest Polymarket betting data, Prime Minister Keir Starmer's resignation is now expected to be announced on 14 Aug 2026, a 2-day delay from the previous forecast of 12 Aug 2026.
The shift in the implied resignation date comes as Polymarket traders adjust their bets on when Starmer will step down as Labour leader and PM. The ~86% exit probability by the new date of 14 Aug suggests growing market confidence in Starmer's continued tenure.
