This market concerns Russian nuclear submarine K-186 Omsk and the unexplained explosion reported near Volchanets/Vostok Bay, Primorsky Krai, on August 26, 2026.

Resolve YES if credible evidence establishes that K-186 Omsk was destroyed, sank, or suffered damage on or about August 26 that rendered it unable to continue normal operational service.

Resolve NO if credible independent evidence establishes that Omsk remained operational after August 26, including a clearly dated photograph/video, identifiable satellite imagery, independently corroborated port appearance, or other convincing evidence of normal post-incident operations.

A Russian Ministry of Defence or Pacific Fleet statement by itself will not be sufficient to resolve NO unless independently corroborated.

If neither outcome can be established by December 31, 2026, resolve N/A.
