Market context

A formal declaration of war against Venezuela by the United States Congress remains an extraordinarily low-probability event, currently priced at 1% on Polymarket. The resolution criteria are strict: only a binding act of Congress, signed into law, qualifies. Authorisations for the use of military force, executive orders, or unilateral military action do not meet the threshold. The settlement window covers a narrow two-week period from 15 to 31 December 2025, meaning traders are pricing the likelihood of a constitutional war declaration occurring within that specific fortnight, not a broader conflict scenario.

Formal declarations of war have become rare in modern American politics. The last declaration Congress passed was against Iraq in 2003; prior to that, Vietnam in 1964. Venezuela has faced sustained US sanctions and diplomatic pressure for over a decade, yet no administration has sought a formal war declaration despite periodic military posturing and humanitarian crises. The 2002 coup attempt and subsequent political instability created flashpoints without triggering congressional action. Historical precedent suggests that even significant geopolitical friction with Latin American states does not automatically translate into formal declarations, which require explicit legislative will and public justification.

Near-term catalysts centre on Venezuelan political developments and US policy shifts. The disputed 2024 presidential election and ongoing humanitarian crisis could intensify rhetoric, but congressional appetite for formal war declarations remains structurally low across both parties. Traders should monitor statements from the incoming US administration in January 2025 and any escalation in cross-border incidents. The compressed December window means any declaration would require rapid legislative movement following a triggering event.

Methodology

We track Will the US officially declare war on Venezuela by 2025? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
