The probability that the Houthis will successfully target shipping by July 31, 2026, dropped sharply by 34.5 percentage points over the last 24 hours, falling from 61.5% to 27.0% on Polymarket. This steep decline in the YES contract price contrasts with whale activity, as large traders collectively placed a net $9K into YES votes during the same period.
Whale buy volume reached $15K while sell volume stood at $6K, with 39 unique whales participating. Overall, Polymarket recorded $36K in 24-hour volume for this market, contributing to a lifetime volume of $102K across 72 unique traders.
The divergence between the downward price move and rising whale bets signals a disconnect between large trader flow and market pricing. While the crowd appears less confident in a successful attack, whales have increased their exposure to YES contracts, indicating differentiated views or strategic positioning.
This split between whale flow and price action adds complexity to interpreting market sentiment and highlights potential volatility in how this geopolitical event is priced. The market’s sharp repricing amid opposing whale behavior suggests uncertainty remains high regarding the likelihood of the Houthis successfully targeting shipping by the specified date.
