This market will resolve to YES if:
The Supreme Court issues a majority opinion that determines the 14th Amendment does not grant citizenship to children born in the United States to unauthorized immigrant parents
The market resolves to NO if any of these occur:
December 31, 2029 passes without such a ruling
The Court issues a majority opinion that determines the 14th Amendment does grant citizenship to such children
Additional points
"Unauthorized immigrant parent" refers to any non-U.S. citizen who was present in the United States without legal authorization at the time of their child's birth
The ruling must address the constitutional question under the 14th Amendment, not merely statutory matters
The determination must be in the Court's majority opinion, not in dicta or separate opinions
