President Trump's September 2026 social media posts, including maps and AI videos suggesting New Mexico be renamed "New America," triggered the Polymarket on whether he would issue an executive order, memorandum, or proclamation directing federal agencies to adopt the change by set deadlines. State officials, including Democratic Gov. Michelle Lujan Grisham and members of the congressional delegation, immediately rejected the idea, noting the name is fixed in New Mexico's constitution and predates both the U.S. and modern Mexico. Unlike prior executive actions rebranding the Gulf of Mexico and Lake Ontario for federal use, renaming a state requires legislative approval, voter ratification, and likely congressional recognition—barriers that have kept implied probabilities low. No formal directive has followed the initial posts, and no state-level steps or legislative sessions appear poised to advance the proposal before key resolution dates.
