Trader consensus prices "No" at 92.5% due to the absence of any official U.S. military mobilization or congressional authorization for invading Mexico, a sovereign neighbor with deep USMCA economic ties that deter such escalation. Recent Treasury sanctions on cartel-linked casinos near the border four days ago, alongside Mexico's extradition of over 90 cartel leaders and joint training of 35 U.S. special forces for 2026 World Cup security, underscore bilateral cooperation over confrontation. President Trump's early-2026 designation of cartels as foreign terrorist organizations prompted Pentagon contingency planning, but Mexico's firm rejection of U.S. troops and declining murder rates signal de-escalation. Only a major cross-border attack or policy reversal could shift odds, though constitutional war powers and diplomatic norms pose high barriers.
