4-bullet brief | narrative

The Polymarket prediction market puts only 1% on North Korea invading South Korea before 2027, despite the DMZ mine incident and Pyongyang's retaliation warning.
The denial-plus-warning posture from Pyongyang is a familiar escalation pattern; the market is treating it as signaling behavior rather than a genuine invasion precursor.
The companion Polymarket contract on Kim Jong Un no longer being Supreme Leader by December 31, 2026 sits at 4%, also a long shot, suggesting no regime instability is priced.
Resolves via Polymarket's uma_oracle; an actual cross-border military incursion would be required for resolution, not a skirmish or mine incident alone.
