Starmer exit odds dip as surprise GDP growth offsets Streeting resignation
· flowframe Pulse
The "Out by 2026" contract on Polymarket is losing its conviction. While the Westminster bubble is screaming for a head on a spike, prediction markets are cooling off on the idea of a summer exit. It's a weirdly calm reaction to a day that began with a cabinet resignation and a full-blown party rebellion.
Health Secretary Wes Streeting finally pulled the trigger today, resigning at 1:00 PM to clear a path for a leadership challenge. He's the biggest name to jump ship since the May 7 local election drubbing. But the timing was eclipsed by the Office for National Statistics, which reported a surprise 0.6% jump in UK GDP. That growth gives Starmer a rare win to wave at the 92 rebels calling for his resignation, especially since 103 other MPs have already signed a pact to keep him in place.
Odds of a pre-2026 departure drifted from 49¢ to 40¢ as the economic data settled the nerves of the bulls. With $3.2M of volume behind the move, the market is now pricing roughly a 40% chance of a successful coup. That's a sharp repricing for a market that was recently a coin flip, suggesting traders think the 81-signature threshold for a formal challenge might be harder to reach than the headlines imply.
The next move depends on the math. Streeting is expected to make his formal pitch later this evening, and the focus is entirely on whether he can secure those 81 nominations. If he doesn't have the receipts by the time the evening news rolls around, Starmer's grip on the leader's office will look a lot tighter.
