Defense Briefing

Seven months after the US-Israeli initial strikes on February 28, 2026, the Iran war is escalating again: Trump is reportedly facing a decision on a new wave of attacks, while sporadic fighting around the Strait of Hormuz continues. The Pentagon DCAS officially records 18 fallen US soldiers; Iranian drones continue to strike Western ships in the region. The blockade of the Hormuz Strait with $1.3 trillion daily trade volume remains the central economic risk for energy markets and global supply chains.

Polymarket rates the continuation of the Israel-Iran ceasefire through end of September at 92% probability – simultaneously, Israeli airspace is rated by the market as remaining closed at 98%, indicating sustained rocket threat. Israeli military operations against Yemen are expected with 48% probability through end of September, signaling expansion of the conflict to additional fronts. The combination of formal ceasefire and active combat readiness demonstrates the structural fragility of the situation across the entire Middle East.

With $6.1 million in trading volume, the Polymarket for the Hormuz blockade is one of the most liquid security policy markets currently – the 60% probability of a US-announced end by September 30 has fallen 16 percentage points over the last month. This signals growing market skepticism about a rapid diplomatic solution and will likely keep oil prices and shipping insurance under pressure. For European energy importers and NATO logistics, the Strait of Hormuz remains the most critical geopolitical chokepoint.

Polymarket sees a 64% probability that an EU state will officially hold Russia responsible for a new sabotage act by end of October – an increase of 5.5 percentage points today alone. The background involves suspicious Russian activities in August 2026 in Bulgaria, Estonia, Germany, Italy, Poland, and Slovakia as well as the arrest of a British national as a Russian sabotage agent in early September. This market for the first time concretely assesses the probability of a publicly attributed hybrid attack – a legally and diplomatically consequential step for the NATO alliance.

Europe's defense spending has risen from $303 billion (2020) to $638 billion (2026); 155-mm ammunition production has quintupled since 2022. According to analysis, most NATO Force Model gaps have been closed following the US troop reduction – yet significant deficits remain in long-range precision weapons, air defense, and strategic airlift. For the defense industry and investors, this means persistently high demand particularly in air defense, drone defense, and ammunition logistics segments.
