Will SCOTUS let USPS enforce ballot-mail rules?

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.
