Iran’s Revolutionary Guard displayed a ballistic missile at a Tehran rally as US-Iran talks collapsed. The market for a US declaration of war on Iran by December 31, 2026, sits at 7.5% YES, down from 8% a week ago.
Market reaction
The missile display has implications for multiple markets. The US declaration of war by end of year is at 7.5%, while the April 30 market is at 0.5%. The market for Iran’s military action against Israel by April 30 is locked at 100%.
Why it matters
The US declaration of war market trades $314 in USDC daily, with $4,248 needed to move the odds 5 points. That makes the market stable but vulnerable to large orders. The Iranian military action markets priced at 100% YES indicate traders treat continued aggression as a given in the near term.
What to watch
A YES share on a US war declaration by December 31 pays $1 if it resolves, a potential 13.3x return at current prices. But a formal war declaration requires congressional support that doesn’t currently exist. Watch for statements from Pete Hegseth or congressional moves toward formal military authorization. Any increase in US military presence in the Persian Gulf could also shift these odds.
