Polymarket 7%

4-bullet brief | narrative

Polymarket prices a 7% chance Russia invades another country in 2026, with trading volume up 7,639% day over day, signaling the Kursk strike is drawing significant fresh attention.
The IAEA's emergency call for restraint after the Kursk nuclear plant strike is the catalyst for the volume surge, though the 7% price itself remains a long shot.
The companion Polymarket contract on a US-Russia military clash by 2026 sits at 5%, consistent with elevated concern that has not yet crossed into consensus alarm.
Resolves via uma_oracle; the key settlement question is whether any armed cross-border action qualifies, making the definition of 'invasion' the critical edge case.
