## About

If the U.S. Supreme Court rules that USPS may enforce both the Federal Ballot Mail Portal registration or enrollment requirements and the related outbound federal ballot-mail pre-acceptance verification requirements for elections on or before November 3, 2026 in any Supreme Court proceeding arising from State of California, et al. v. United States Postal Service, et al., D. Mass. No. 1:26-cv-13917-IT before Nov 3, 2026, then the market resolves to Yes.

The specified Case is any Supreme Court proceeding arising from State of California, et al. v. United States Postal Service, et al., D. Mass. No. 1:26-cv-13917-IT.

The ruling must:
Be issued in a written order, opinion, judgment, or decision by the U.S. Supreme Court in that proceeding
Address the matter described by the specified judgment

The following do NOT satisfy the Payout Criterion:
A procedural standing or ripeness order that does not itself permit enforcement
A grant or denial of certiorari without operative relief
A temporary administrative stay entered only for briefing or consideration
Oral, tentative, leaked, scheduling, show-cause, or non-substantive minute orders
Relief limited to envelope design, voluntary portal development, or another provision without both specified components

A stay or vacatur qualifies only if its operative text itself permits the portal and verification requirements to be enforced. The August 24 order in Trump v. California does NOT qualify. Per curiam opinions and summary orders count if they match the specified judgment.
