Traders on Polymarket are unanimous in their view that Prime Minister Keir Starmer will not call a general election before the summer of 2026, assigning a 0% probability to the event. The contract, which has attracted $64,000 in volume, reflects a market consensus that the next election will occur after the specified deadline, likely in line with the statutory requirement for a vote by January 2029. No other prediction platforms—Kalshi or Manifold—currently offer contracts on this question, limiting cross-platform comparison. The absence of any positive probability suggests that traders see no plausible scenario—such as a sudden political crisis or a strategic early election—that would trigger an earlier vote. Without recent news headlines to explain the market's stance, the 0% figure appears to stem from baseline expectations of electoral timing under current law and political conditions.
