New testimony increases pressure on UK’s Starmer over US envoy choice

New testimony about Keir Starmer’s envoy choice has increased pressure on the UK Prime Minister, with the market on Starmer being out by June 30, 2026, at 40.5% YES, unchanged from yesterday.

Market reaction

The Starmer out by June 30, 2026 market holds at 40.5% YES, while the December 31, 2026 date is at 70.5% YES, down from 66% yesterday. The largest move was a 2-point drop in the December market.

Why it matters

Volume at $27,552 in USDC over the past 24 hours. The June 30 market moves 5 points with just over $3,000, making it vulnerable to larger trades, while the December market requires over $13,000 for the same move. The biggest action in the past day was a 2-point spike early in the morning.

This testimony compounds previous controversies and increases Starmer’s political exposure. At 40.5¢, a YES share pays $1 if he’s out by June, a 2.77x return. That bet depends on Starmer either failing to survive until local elections or facing a leadership challenge before then.

What to watch

Any shifts in Labour party dynamics or cabinet resignations. Angela Rayner’s or Wes Streeting’s positioning matters most. Watch for official statements from Starmer’s office responding to the testimony.
