On 30 June 2026, the U.S. Supreme Court decided West Virginia v. B.P.J., 609 U.S. ___ (No. 24-43). The Court held that states may restrict girls’ and women’s school sports to biological females — Title IX (biological-sex meaning) and Equal Protection (6–3 on the Equal Protection path per contemporaneous coverage).

Title IX school sports and World Athletics elite rules are converging on biological-sex categories — local club rules still need their own text.
Citizen impact: U.S. states that wrote female-category school sports statutes now have a Supreme Court holding on their side. Elite track and field athletes under World Athletics face SRY gene testing for the female World Rankings category (Eligibility Rule 3.5, effective 1 September 2025, including Tokyo 25 Championships framing). Club/masters local rules are not automatically identical — check the specific federation text.

World Athletics SRY rule

World Athletics’ press materials state athletes compete in the female World Rankings category only if biologically female, with SRY testing as the eligibility tool for that category.

Contested: ACLU and plaintiffs: equal athletic opportunity and discrimination claims. States and World Athletics: fairness and safety after male puberty. The Bow, New Hampshire “XX” wristbands case is a speech fight at a game — related, not an eligibility merits holding.

What we refuse

No claim that SCOTUS banned all trans people from any sport worldwide. No claim that B.P.J. decided prison or shelter law. No collapsing club rules into World Rankings regs without checking.

Bottom line

States may keep girls’ school sports female; World Athletics requires SRY tests for elite female category ranking. Read the opinion PDF and the federation rule — not viral summaries.
