Labour insiders are pushing back against demands for an inquiry into Prime Minister Keir Starmer’s appointment of Lord Mandelson amid vetting failures. The odds of Starmer resigning by December 31, 2026, sit at 68%, up from 66% a day ago.
The internal friction within Labour is moving markets that track Starmer’s political survival. The June 30, 2026 market shows a 39.5% chance of Starmer’s exit, down from 42% last week. The December 31, 2026 contract jumped 2 points in the past 24 hours.
The term structure shows a 29-point gap between the June 30 and December 31, 2026 contracts. Traders are pricing in a catalyst during the second half of the year, whether a leadership challenge or a no-confidence vote. There are 251 days until year-end.
In the past day, $29,563 in USDC traded across these markets. It takes only $998 to move the June 30 odds by 5 points, which makes that contract vulnerable to large trades. The largest recent move was a 3-point jump in the June 30 contract.
The Mandelson appointment scrutiny could compound pressure on Starmer’s leadership, particularly if Labour figures or donors withdraw support. A YES share for Starmer’s resignation by end of 2026 trades at 68¢, offering a potential 1.47x return if resolved.
Watch for developments from Labour’s National Executive Committee or any public moves by Angela Rayner or Wes Streeting, which could shift these odds.
