Trump must act by May 1 to justify ongoing military operations against Iran, as required by the War Powers Resolution. This legal framework mandates congressional approval to continue military actions beyond 60 days. The countdown began on March 2, and without congressional backing, these operations will need to conclude by the deadline.
The current probability of a formal war declaration by the U.S. against Iran by the end of December 2026 sits at only 7%. Meanwhile, the market indicates an extremely low chance of this declaration occurring before May, with an estimated 0.5% chance as of April 30. Traders display skepticism about any immediate escalation in military actions, reflecting a significant 7-point jump in perception from April 30 to December 31. This indicates traders are leaving some possibility for actions in the latter part of the year without envisioning a dramatic shift before May.
The urgency surrounding this deadline compels Trump to secure congressional approval. If not achieved, military activities will have to halt. From an investment standpoint, purchasing a position in the potential declaration of war by December offers substantial returns, yet it hinges on the vital assumption that Trump can galvanize support within the next 252 days.
Investors should keep a close watch on movements in Congress, especially any announcements from Speaker Johnson or indications of public hearings regarding authorization. At present, the likelihood of diplomatic resolutions outweighs the military options, making this an interesting period for traders and investors alike.
