Recent Houthi attacks on Saudi-linked oil tankers and commercial vessels in the Bab el-Mandeb Strait and Red Sea, including the Aug. 12 strike on the Tihamah cargo ship that produced fatalities, have driven elevated implied probabilities for successful targeting on recent dates. These actions stem from the July 20 blockade declaration against Saudi shipping amid the broader Iran-US conflict and Hormuz disruptions, prompting tanker traffic declines of over 40% in key weeks, sharp rerouting around the Cape of Good Hope that adds 10–14 days and substantial bunker costs, and higher war-risk insurance premiums now covering calls at Yanbu and Jeddah. Saudi crude exports via Red Sea pipelines face direct pressure, tightening global supply dynamics and supporting elevated energy benchmarks. Traders are monitoring multinational naval responses and any further escalation ahead of the Aug. 31 resolution.

Attacks on military vessels will not be considered.
Missile/drone strikes targeting a ship that are intercepted or otherwise do not directly impact the vessel will not be considered, regardless of damage through debris.
Seize control refers to Houthi forces forcefully boarding and taking control of a commercial ship.
Qualifying incidents include, but are not limited to, drone and missile strikes, aerial bombings, and kinetic actions carried out by Houthi operatives in person, such as seizing a ship by force.
The primary resolution source for this market will be a consensus of credible reporting.
If a kinetic incident occurs, but, on the specified date, 11:59 PM AST, material ambiguity remains as to whether the incident can be attributed to Houthi operatives, this market may remain open for an additional 3 calendar days, AST. If, at such time, attribution of the incident still cannot be confirmed, this market will resolve to “No”.
