Starmer's Odds: Exactly Even Money
Keir Starmer is facing a critical moment. Polymarket is pricing a 48.5% chance the Prime Minister leaves office by June 30, 2026. The market is split nearly down the middle.
The odds
Starmer out by June 30, 2026: 46% YES. $1.1M volume on the active bracket. The December 2025 deadline resolved NO.
The trend this week is flat. No major movement in the past seven days.
What the polls say
Latest polling from YouGov shows Labour approval at 32%, down from 42% at the start of 2025. Starmer’s personal net favorability is minus 18.
The data suggests voter fatigue is real and accelerating.
What the market says
The market is pricing in genuine structural risk to his tenure. This isn’t tail-risk pricing. Coin-flip odds mean traders see a real 50-50 scenario.
Either Starmer can stabilize Labour’s numbers in the next three months, or the party will move to replace him. The market has priced both paths as equally likely.
The wildcard
Budget announcement next month. Local election performance in May. Any major Labour MP resignation.
These events could move the odds 10-15 points quickly.
Starmer is at even odds. The market sees his tenure as genuinely contested, not secure.
