The prediction market Polymarket, the only platform with data on this event, shows a 1% probability that the next UK election will be called by June 30, 2026. With $62,000 in volume, traders are effectively pricing in a 99% chance that the election will be called after that date, likely in 2027 or later. This reflects the standard five-year electoral cycle, as the last general election was held in July 2024, meaning the next must occur by August 2029. No specific external trigger has been identified in today's news flow to shift expectations, and the low probability aligns with historical norms where early elections are rare without a parliamentary crisis or snap vote. The absence of data from Kalshi and Manifold limits cross-platform comparison, but Polymarket's volume suggests a liquid market with consistent sentiment.
