Will another country conduct military action against Iran by April 15, 2026?

Analysis

The 13.5% market price seems roughly accurate. While US-Israel strikes on Iran have escalated since February 28, drawing another country into direct military action within 13 days faces major barriers: 1. Most regional powers prefer letting US/Israel handle the military response rather than risk Iranian retaliation on their territory 2. 13 days is extremely short for the major policy decision required to launch strikes on Iran 3. Saudi Arabia, the most likely candidate, reportedly urges attacks but maintains "cautious neutrality" - suggesting preference for proxy involvement 4. The US is reportedly pursuing a "15-point de-escalation plan" which would discourage third-party escalation The 21% probability for April 30 (just 15 days later) vs 13.5% for April 15 suggests traders recognize this needs more time to develop. While escalation risk is real, direct military action by a third country requires overcoming significant diplomatic and strategic hesitations that typically take weeks/months to resolve.
