Resolution criteria on PolyGram: This market will resolve to "Yes" if the United States commences a military offensive intended to establish control over any portion of Mexican land territory by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". For the purposes of this market, land de facto controlled by Mexico or the United States, as of market creation, will be considered the sovereign territory of that country. The resolution source for this market will be a consensus of credible reporting.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Will the U.S. invade Mexico in 2026? | 7% YES | 94% NO |
A military invasion of Mexico by the United States would represent a fundamental rupture in post-World War II hemispheric relations and international law. The current 7% implied probability on Polymarket's order book reflects the market's assessment that such an event remains extraordinarily unlikely within the 2026 calendar year, though traders are pricing in non-negligible tail risk. Resolution requires a formal military offensive intended to establish territorial control, distinguishing this from cross-border operations, airstrikes, or unilateral security actions that fall short of invasion.
Historical precedent offers limited guidance for assessing this probability. The last significant U.S. military intervention in Mexico occurred in 1916 when General Pershing led a punitive expedition into Chihuahua, though this was framed as pursuit of Pancho Villa rather than territorial conquest. Since then, U.S.-Mexico relations have evolved through formal alliance structures, trade integration via NAFTA and USMCA, and institutional security cooperation. No major power has invaded another in the Western Hemisphere since 1983. The baseline expectation embedded in the 7% probability reflects the absence of structural conditions that historically precede major power conflicts: territorial disputes, resource competition, or existential security threats between the two nations.
Traders monitoring this market should track escalations in cross-border security rhetoric, particularly around drug trafficking operations or migration enforcement, as well as any significant deterioration in U.S.-Mexico diplomatic relations. Recent statements by U.S. officials regarding military options for addressing organised crime have generated market attention, though such rhetoric has not historically translated into invasion scenarios. The resolution window extends through end-2026, meaning geopolitical shifts over the next two years will determine whether this tail-risk probability adjusts materially.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Will the U.S. invade Mexico in 2026?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.

The market has been open for 4 months — the price has had time to stabilise as new information arrived.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
