Iran-backed Houthi rebels in Yemen escalated attacks on Red Sea shipping last week, firing missiles at two vessels including the Greek-owned Eternity C on May 18 amid ongoing U.S. and allied airstrikes that have degraded Houthi capabilities but not halted operations. This follows Iran's April 13 seizure of the Israeli-linked MSC Aries in the Strait of Hormuz, a rare direct action signaling potential naval escalation tied to the Iran-Israel shadow war. No confirmed Iranian strikes on commercial shipping have occurred since 2019 tanker incidents, but threats persist amid U.S. carrier deployments and diplomatic pressure for de-escalation. Traders monitor Houthi strike success rates—historically low at under 5%—and upcoming U.S. policy shifts post-Israel aid approvals for probability shifts.

Attacks on military vessels will not be considered.
Only military actions by Iranian forces explicitly claimed by the Islamic Republic of Iran, or confirmed to have originated from Iranian territory will count toward the resolution of this market. Attacks by proxy forces (i.e. Hezbollah, Houthis, etc.) will not count toward the resolution of this market.
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.
Qualifying incidents include, but are not limited to, drone and missile strikes, aerial bombings, and kinetic actions carried out by Iranian 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 the date/time of a qualifying incident cannot be confirmed by a consensus of credible reporting by the end of the second calendar date after the specified date, it will resolve to "No" regardless of whether a strike is later confirmed to have taken place.
