President Donald Trump’s early September 2026 social media posts and AI-generated videos suggesting New Mexico be called “New America” triggered the Polymarket, but traders assign very low odds because the president lacks unilateral authority to change a state’s name. New Mexico’s constitution explicitly fixes the name, requiring legislative approval and a voter referendum for any amendment. Democratic state leaders, including Gov. Michelle Lujan Grisham and both senators, immediately rejected the idea, citing the state’s pre-U.S. history. Trump later described the proposal as something he would not push, distinguishing it from his successful executive orders renaming the Gulf of Mexico and Lake Ontario for federal use. No formal directive or congressional action has followed, and the state’s Democratic lean plus constitutional hurdles make near-term resolution improbable absent an unlikely state-level initiative.
