This prediction market addresses whether the United States will ratify a new constitutional amendment during Donald Trump's potential second presidential term, which would run from January 20, 2025, to January 20, 2029. The U.S. Constitution has been amended only 27 times since its ratification in 1788, with the last amendment, the 27th, ratified in 1992 after a 202-year proposal process. Adding an amendment requires clearing the highest procedural bar in American government: a two-thirds vote in both the House and Senate, followed by ratification by three-fourths of state legislatures, or a constitutional convention called by two-thirds of state legislatures. The difficulty of this process makes any new amendment a historically significant event. Interest in this market stems from political discussions about potential amendments on topics like congressional term limits, balanced budget requirements, or electoral college reform, which have gained traction in some Republican circles. The market resolves to 'Yes' if any new amendment is added before the end of Trump's term, with an early close if the event occurs. The outcome hinges on whether political momentum can overcome the formidable structural barriers designed by the Founding Fathers to make constitutional change exceptionally difficult.

Historical Context

The U.S. Constitution's amendment process, outlined in Article V, was designed to be arduous to ensure stability. Of the approximately 12,000 amendments proposed in Congress since 1789, only 33 have garnered the two-thirds vote needed to be sent to the states for ratification. The 20th century saw periods of concentrated amendment activity: four amendments were ratified between 1961 and 1971, including the 25th (presidential succession) and 26th (voting age). The most recent amendment, the 27th, regarding congressional pay, was proposed in 1789 as part of the original Bill of Rights but wasn't ratified until 1992, demonstrating the lengthy timeline possible. The last amendment to originate and complete the entire process in the modern political era was the 26th Amendment in 1971, ratified in just 3 months and 8 days during the Vietnam War. The 'Convention of States' method, requiring applications from 34 states, has never been successfully used to propose an amendment, though it came close during the Progressive Era with calls for direct election of senators, which was eventually achieved through the congressional proposal method (17th Amendment). The high failure rate of amendments, even those with popular support like the Equal Rights Amendment (which failed to meet its ratification deadline), underscores the institutional inertia.
