The market on whether the Houthis will successfully target shipping by July 31, 2026, saw a dramatic pullback in its YES price, dropping 54.5 percentage points from 84.0% to 29.5% over the last 24 hours. This sharp decline contrasts with whale activity, which flowed $7K net into YES contracts, including $10K in buys against $4K in sells, involving 37 unique whales.
Polymarket’s 24-hour volume for this market reached $42K, contributing to a lifetime volume of $99K with 65 unique traders participating overall. The divergence between whale flow and price movement is notable: while the tape repriced the contract sharply lower, whales increased their exposure to YES, a rare disconnect flagged in the data.
This split suggests differing interpretations of the risk or timing of a successful Houthi targeting event among large traders versus the broader market. The market’s swift price drop signals growing skepticism or new information reducing the immediate likelihood, yet whale buying indicates some large players maintain conviction in the YES outcome.
The combined picture of falling prices amid rising whale demand highlights ongoing uncertainty and a contested narrative on this geopolitical event’s probability within Polymarket’s ecosystem.
