Arizona voters will decide Proposition 317 on November 3, 2026, a legislatively referred statute that declares drug cartels terrorist organizations and directs the state Department of Homeland Security to use all available authority against them, including human smuggling and trafficking linked to prior voter-approved measures such as Proposition 314. The Republican-led legislature placed the measure on the ballot in June 2026 with straightforward majority approval, and the secretary of state finalized official language in August. Arizona’s position along major trafficking corridors and recent enforcement emphasis have shaped trader assessments, producing an 86% implied probability for passage that reflects broad legislative backing and limited organized opposition to date. Scheduled events within the resolution window include standard campaign activity ahead of the general election.
