The prediction market asking whether the Houthis will successfully target shipping by July 31, 2026, saw its YES contract price plunge 23.0 percentage points over the last 24 hours, falling from 50.0% to 27.0%. This move was accompanied by a notable divergence between whale activity and market pricing.
Despite the steep drop in the YES price, whales collectively bought $15K worth of YES contracts and sold only $6K, resulting in a net inflow of $9K into the YES side. This flow divergence, flagged in the data, indicates that large traders were increasing their exposure to YES even as the broader market pushed prices lower.
The 24-hour volume on Polymarket for this question reached $31K, contributing to a lifetime volume of $103K and involving 72 unique traders overall. Whale participation was significant, with 39 unique whales active in the last day.
This contrasting picture of price and whale flow suggests that while general market sentiment turned sharply against the likelihood of a successful Houthi shipping attack by the deadline, a substantial cohort of large traders maintained or increased their conviction in that outcome. The split between price and whale behavior highlights tension in the market’s assessment of this geopolitical risk, signaling an ongoing debate among informed participants about the event’s probability.
