Analysis

11d ago

This market displays extreme asymmetry with a 1430.7% implied yield on the Yes side versus just 14.0% on the No side, suggesting either severe underpricing of conflict risk or heavy skew toward the consensus view that NATO members will not clash militarily. The 9¢ price reflects only a 9% probability despite 258 days remaining until expiry, yet the $26k open interest against just $5 in daily volume indicates illiquidity that could amplify price swings if new information emerges. The zero spread and neutral regime score (0.341) suggest the market is relatively stable, but the elevated Cliff Risk Index of 10 warns that resolution could be binary and abrupt, making this a speculative position rather than a liquid hedge.

Resolution rules

This market will resolve to "Yes" if there is a military encounter between the military forces of at least two NATO member states between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A "military encounter" is defined as any incident involving the use of force, such as missile strikes, artillery fire, exchange of gunfire, or other forms of direct military engagement between the military forces of at least two NATO member states. Non-violent actions, such as warning shots, artillery fire into uninhabited areas, or missile launches that land in territorial waters or pass through airspace, will not qualify for a "Yes" resolution. Intentional ship ramming that results in significant damage to (e.g., a hole in the hull) or the sinking of a military ship by another will count toward a "Yes" resolution, however minor damage (scrapes, dents) will not. Note: For the purposes of this market, coast guard services or equivalent forces will be considered part of a country’s military only if they are officially designated as military forces under that country’s law or command structure; purely civilian or law-enforcement maritime agencies will not be considered military forces. The resolution source for this market will be a consensus of credible reporting.
