Starmer’s Labour Party projected to lose seats in May 7 UK elections

Keir Starmer’s Labour Party is projected to lose seats in the May 7 UK local and regional elections. The market on Starmer being ousted by December 31, 2026, has jumped to 72%.

The June 30, 2026 market sits at 46.5%, up from 41% yesterday. The 25-point spread between the June and December dates suggests investors expect the period between those months to matter most. Potential losses in the Welsh Senedd, where Labour faces Plaid Cymru and Reform UK, could be a trigger. These markets are thin: $998 moves the June market by 5 points.

Total trading volume across these markets is $29,563, showing active interest but not deep conviction. The largest price movement in the last 24 hours was a 3-point spike, a sign of sensitivity to incoming news. The December 2026 market is thicker, requiring $5,843 to shift five points.

Losing key seats could seriously weaken Starmer’s position within the party. At 46.5%, buying YES at 46¢ pays $1 if he’s out by June 30, a 2.17x return. The bet turns on Labour’s election performance and how the party reacts internally afterward.

Watch for the Labour NEC’s response after the election and any moves by Angela Rayner or Wes Streeting. Sharp poll shifts or leadership bids would move these markets fast.
