Resolution criteria
This market resolves YES if Iran successfully strikes the Diego Garcia base with a ballistic missile before June 1st, 2026. A successful strike means the missile reaches and impacts the base or its immediate vicinity, causing damage. Missiles that fail to hit the base or are intercepted before impact resolve NO. Resolution will be determined by official statements from U.S. or U.K. military authorities, major news outlets citing military sources, or confirmed damage assessments.
Background
The conflict began on February 28 with U.S. and Israeli airstrikes against Iranian targets. On March 21, 2026, Iran launched two ballistic missiles at Diego Garcia, the joint U.S.-U.K. military base in the Indian Ocean. Both missiles failed to hit the airbase—one missile failed in flight and a U.S. warship reportedly fired an SM-3 interceptor at the second.
Diego Garcia, located in the British Indian Ocean Territory, is a key strategic hub for U.S. forces, hosting long-range bombers, nuclear submarines and guided-missile destroyers. Diego Garcia is approximately 4,000 kilometers from Iran.
Considerations
The March 21 attack marked Iran's first operational use of intermediate-range ballistic missiles and a significant attempt to reach far beyond the Middle East and threaten U.S. interests. Iranian Foreign Minister Abbas Araghchi had previously indicated his country's military had limited its ballistic missile range to 2,000 kilometers, making the successful launch to Diego Garcia a demonstration of previously undisclosed capability. The base's remote location and advanced air defenses present significant obstacles to a successful strike, though Iran has now demonstrated the range to attempt one.
