Will the US officially declare war on Venezuela by...?

Resolution Criteria

This market will resolve to "Yes" if the United States formally declares war on Venezuela through an act of Congress between December 15 and December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No." To qualify, Congress must pass a formal declaration of war, consistent with its constitutional authority under Article I, Section 8. Authorizations for the use of military force (AUMFs), executive orders, presidential statements, or military actions do not qualify unless accompanied by a formal declaration of war enacted by Congress and signed into law. The resolution source will be a clear consensus of credible reporting.

A formal US declaration of war on Venezuela by the end of December 2025 is the heavily disfavoured outcome in this market, with trading volume concentrated almost entirely on 'No'. Resolution requires Congress to pass a constitutionally grounded declaration of war — not merely an authorisation for the use of military force — between 15 and 31 December 2025. The resolution deadline for the market itself is 30 June 2026.

Market structure

This is a binary market with two outcomes: 'Yes' (formal congressional declaration of war on Venezuela by 31 December 2025) and 'No'. Volume is overwhelmingly concentrated on 'No'. Resolution requires a formal act of Congress under Article I, Section 8 — executive orders, presidential statements, and AUMFs explicitly do not qualify. The source of truth is a clear consensus of credible news reporting. The market resolves no later than 30 June 2026.

Background

The United States has not formally declared war on any nation since 1942, when Congress declared war on Romania, Bulgaria, and Hungary during the Second World War. Since then, military engagements — including Korea, Vietnam, Iraq, and Afghanistan — have been conducted under authorisations for the use of military force rather than formal declarations. US-Venezuela relations have been strained for years, marked by sanctions, diplomatic expulsions, and Washington's recognition of opposition leadership. Tensions escalated further following disputes over Venezuelan territory and migration flows, prompting some hawkish commentary. However, no legislative proposal for a formal declaration of war against Venezuela has advanced through Congress.

Key factors

A formal declaration of war requires majority passage in both chambers of Congress, followed by presidential signature — a process with no modern precedent in the post-war era. The compressed window of 15–31 December 2025 further constrains any possible resolution to 'Yes', as Congress typically operates on a reduced schedule over the holiday period. The distinction between a formal declaration and an AUMF is legally and constitutionally significant; the resolution criteria explicitly excludes AUMFs, executive orders, and unilateral military action. Any diplomatic incident, military confrontation, or territorial dispute involving Venezuela could theoretically accelerate legislative debate, but translating that into a constitutionally compliant declaration within the specified window would require extraordinary and rapid consensus across both chambers. The current geopolitical climate, congressional appetite for formal war declarations, and the short timeframe all bear on whether the narrow 'Yes' path closes entirely.
