Opposition leaders are demanding Starmer’s resignation over the Mandelson scandal as he prepares to address MPs. “Starmer out by June 30, 2026” sits at 36.5% YES, down from 42% yesterday but up from 24% a week ago.
Trader attention has shifted to the June 30, 2026 market, with 73 days left until resolution. The 2-point drop yesterday follows a 12.5-point rise over the past week, a pattern consistent with a sharp repricing followed by partial correction. The December 31, 2026 market is at 65.5% YES. The 26-point spread between the June and December contracts suggests traders expect a meaningful development in that six-month window but aren’t confident it happens before summer.
Daily volume is $16,715 in USDC, and $3,486 is enough to move the June 30 odds by 5 percentage points. The largest recent move was yesterday’s 2-point drop. This is a moderately liquid market where a single large order can produce noticeable swings.
The odds reflect real skepticism about Starmer’s ability to survive the scandal. The sequence of events, from opposition calls to the upcoming MP address, points to a substantive leadership challenge rather than routine political noise. At 36¢, buying YES pays $1 if he resigns or is ousted by June 30, a 2.7x return. That bet requires believing the political pressure escalates substantially within 73 days.
Starmer’s address to MPs on April 20 is the next concrete catalyst. Watch for shifts in support from specific Labour figures or internal party polling that could move trader positioning.
