US legal adviser claims Iran war justified by Tehran’s decades of aggression

The US State Department’s top lawyer claims the Iran conflict is justified as self-defense. The “US Declaration of War on Iran” market sits at 7% YES.

Reed Rubinstein’s statement could push odds for a formal US war declaration higher, particularly in the December 31, 2026 market, which trades at 7% YES. The April 30, 2026 market remains at 0.4% YES, showing skepticism about an imminent declaration. The 7-point spread over 245 days between the two contracts suggests traders expect a potential catalyst sometime between April and December.

The US-Iran Peace Deal market for April 30 sits at 9.5% YES, down from 10% yesterday and 61% a week ago. The May 31 and June 30 contracts are also falling, at 36% and 52% YES respectively.

Volume in the peace deal markets hit $854,588 in real dollars over the past 24 hours; the war declaration markets traded $392. Order book depth for the peace deal markets requires $27,667 to move 5 points, compared to just $2,981 for the war declaration market, making the latter far more susceptible to sharp moves.

Rubinstein’s statement frames US actions as a continuation of an existing conflict rather than a new war, which could sway Congressional opinion toward a formal declaration. Buying YES at 7¢ pays $1 if declared by December 31, a 14.3x return.

Watch for Congressional reactions and any formal request for a war declaration from President Trump. A shift in language from Secretary of War Pete Hegseth would also be significant.
