Polymarket traders have priced the likelihood of a UK general election being called by June 30, 2026, at exactly 0%, based on $63,000 in volume. This indicates a near-universal expectation that Prime Minister Keir Starmer's Labour government will not trigger an early election before that date, despite the next statutory deadline being January 2029. The market's stark consensus reflects a lack of political pressure or parliamentary maneuvering that would force an early vote, though no specific news headlines have emerged to explain the odds. With no data from Kalshi or Manifold, Polymarket provides the sole window into trader sentiment, and its zero-percent probability suggests a firm belief in the current electoral timeline.
