The probability that there will be no next Home Secretary of the UK in 2026 dropped sharply by 42.0 percentage points over the last 24 hours on Polymarket, falling from about 91.5% to 49.5% as of July 15. This plunge marks a dramatic reversal in market sentiment on this outcome.
Despite the steep decline in the YES price, whale activity did not mirror the sharp sell-off. Data shows net whale flow of $2K into YES contracts, with whale buy volume at $10K and sell volume at $8K across 60 unique whale traders. This divergence between whale behavior and the price move suggests that larger traders remained more confident in the YES outcome while the broader market sharply repriced it lower.
The 24-hour trading volume on this market totaled $10K, contributing to a lifetime volume of $32K and involving 136 unique traders. Notably, the Polymarket Breaking YES price at 49.5% contrasts with the Polydata on-chain mid-price of 87.5%, indicating a significant discrepancy between the real-time market price and on-chain data.
The split suggests uncertainty and conflicting sentiment about the likelihood of there being no next Home Secretary in 2026.
