Prediction markets show a 24.5% probability of a NATO-Russia military clash by December 31, 2026, after the Wall Street Journal reported that new U.S. intelligence assessments suggest Russian President Vladimir Putin may test NATO’s resolve with a limited attack on an alliance member. The reported scenarios included cyber operations, a ground incursion, or deployment of armed forces onto NATO territory within the next few years or potentially in the coming weeks. The report has increased attention on Russian military movements near NATO borders, statements from Putin, NATO officials and U.S. defense authorities, and any diplomatic or de-escalatory steps that could alter the outlook. A separate prediction market priced the probability of a direct U.S.-Russia military clash at 4% YES.
