US strikes on Iran heighten odds of military escalation

The U.S. has intensified strikes on Iran, claiming to weaken its military, while Iran insists on acting in self-defense. The probability of U.S. forces entering Iran by April 30 is now 56% YES, slightly down from 58% a week ago.

The ongoing military campaign has impacted several prediction markets. For the US forces entering Iran by April 30, the odds sit at 56% YES, reflecting a stable expectation of increased military engagement. Meanwhile, the December 31 market shows a 65.5% YES, indicating a longer-term view that further escalations might unfold, despite a slight decrease from last week’s 70%.

In contrast, the US-Iran ceasefire by April 7 has plummeted to 8.5% YES, down from 28% a week ago, as continued hostilities reduce hopes for an immediate ceasefire. The term structure suggests traders anticipate potential diplomatic breakthroughs more likely by April 30 with odds at 38.5% YES.

Volume in these markets is substantial, with $2,160,813 in USDC traded in the “US forces enter Iran” market over the past 24 hours. The April 30 market alone trades $1,553,385/day, indicating strong interest and liquidity. However, moving the price by 5 percentage points requires $78,519, suggesting institutional participation.

The escalation signals a potential shift in the conflict’s trajectory rather than mere noise. The assassination of Iranian Supreme Leader Ali Khamenei has heightened regime instability risks, with the Iranian regime fall by June 30 sitting at 10.5% YES, down from 22% a week ago. At 10.5¢, a YES share pays $1 if the regime falls by June 30, offering a 9.5x return—a high-risk, high-reward play predicated on continued internal destabilization.

Watch for CENTCOM operational updates and any public appearances by Mojtaba Khamenei. Changes in military posture or diplomatic engagements will be key indicators for market movements.
