Five-second answer

Claim we investigated

Federal law, the Women's Tennis Association, World Athletics, and the International Olympic Committee have all adopted policies to protect eligibility for the female category.

Mostly true. The WTA, World Athletics and IOC limit the female category; federal policy does too, but no statute requires it. Each body's own announcement, the text of Executive Order 14201, the Supreme Court's June 30, 2026 opinion and the congressional record together confirm the three sports policies and show that federal policy rests on executive action and a ruling that permits, rather than a law that mandates, sex-based eligibility.

One-minute summary

What the evidence establishes

  • Established. The International Olympic Committee limited every female category at the Olympic Games and other IOC events to biological females on March 26, 2026, using a one-time SRY gene screen, from the 2028 Games onward.
  • Established. World Athletics excluded transgender women who had gone through male puberty from female world-ranking events in 2023, and has required a once-in-a-lifetime SRY test for the female category since September 1, 2025.
  • Established. The Women's Tennis Association replaced its testosterone-based eligibility rule with a required one-time SRY gene screening in July 2026.
  • Established. Federal policy opposes male participation in women's sports under Executive Order 14201 (2025), and on June 30, 2026 the Supreme Court held that Title IX and the Constitution allow states to limit girls' teams to biological females.
  • Not shown. No act of Congress requires sex-based eligibility: the Protection of Women and Girls in Sports Act passed the House in 2025 but failed a Senate cloture vote, 51-45. 'Federal law' is accurate only as the executive branch's and the Court's reading of Title IX.
  • Established. The IOC president's quote is accurate apart from a dropped opening 'So,': Kirsty Coventry said it is 'absolutely clear that it would not be fair for biological males to compete in the female category.'
  • Context. The three sports-body policies govern elite competition and use a gene test; the IOC's does not apply to grassroots sport. I-638 would apply to Washington school sports and relies on a provider's signed statement.
Important context: Initiative IL26-638 is on Washington's November 3, 2026 ballot. It would bar students the measure defines as biologically male from female-only school sports and require a health care provider to verify each entrant's sex. The Yes argument in the state voters' pamphlet says the measure would align Washington with world sports policies and names four examples. This check rates that sentence and the IOC president's quote that follows it. It does not judge whether those policies, or the measure, are wise.

Federal law, the Women's Tennis Association, World Athletics, and the International Olympic Committee have all adopted policies to protect eligibility for the female category.

Review of the IOC's policy announcement, as reprinted verbatim by the Olympic Council of Asia International Olympic Committee, Olympic Council of Asia Switzerland 2026 On March 26, 2026 the IOC Executive Board approved a Policy on the Protection of the Female (Women's) Category in Olympic Sport. For all disciplines at the Olympic Games and other IOC events, individual and team, eligibility for any female category is limited to biological females, determined in the first instance by a one-time SRY gene screen. It applies from the 2028 Los Angeles Games, is not retroactive, and does not apply to grassroots or recreational sport.

Common questions

“In March 2026, the IOC president stated, "It is absolutely clear that it would not be fair for biological males to compete in the female category."”

Our rating: True

Accurate. In the IOC's March 26, 2026 announcement, President Kirsty Coventry said: 'At the Olympic Games, even the smallest margins can be the difference between victory and defeat. So, it is absolutely clear that it would not be fair for biological males to compete in the female category.' The pamphlet omits the opening 'So,' and the sentence before it, which does not change the meaning. She added that in some sports it would not be safe.

“Federal law requires schools to keep transgender girls out of girls' sports.”

Short answer: Not by statute

No act of Congress says so. The bill that would have written it into Title IX passed the House in January 2025 but failed a Senate cloture vote, 51-45, in March 2025. The Supreme Court held in June 2026 that states may limit girls' teams to biological females, not that they must. The requirement that does exist comes from the executive branch: Executive Order 14201 and the Education Department's reading of Title IX, which it enforces through investigations such as the one it opened into Washington's superintendent's office in 2025. That reading has not been tested to a final ruling against a state that allows transgender girls to compete.

“These are elite-sport rules, so I-638 would not 'align Washington with world sports policies'.”

Short answer: Partly

Partly right. The IOC says its policy does not apply to grassroots or recreational sport; World Athletics applies its rule to world-ranking competition; the WTA rule covers its professional tour. The methods also differ: the three bodies use a one-time SRY gene screen, while I-638 asks a provider to sign a statement based on anatomy, genetics or testosterone levels. But the federal executive order and the Supreme Court's ruling do concern school sports, and 27 states have similar school-sports laws. The rated sentence says only that these bodies adopted female-eligibility policies, which is accurate.

“SRY gene tests are not a reliable way to determine sex.”

Short answer: Disputed

Scientists disagree. World Athletics calls the SRY test a reliable proxy for biological sex, and the IOC and WTA have adopted it. Andrew Sinclair, whose team discovered the SRY gene, has written that the test shows only whether the gene is present, not whether it functions; World Athletics, for example, makes an exception for athletes with complete androgen insensitivity. The dispute concerns how to run the policies, not whether the policies exist, so it does not change this rating.

“The WTA had no such policy when the pamphlet argument was written.”

Short answer: It had one either way

The WTA announced its SRY screening on July 19, 2026, and the date the Yes committee submitted its argument is not public. Before then the WTA already had a female-category eligibility rule that let transgender women compete only after two years of lowered testosterone. Either rule is a policy setting eligibility for the female category, and the stricter one was in force when the pamphlet was published in September 2026.

Conclusion

Three of the four examples in the Yes argument are straightforward. The International Olympic Committee announced on March 26, 2026 that eligibility for any female category at the Olympic Games and other IOC events is limited to biological females, determined by a one-time SRY gene screen, starting with the 2028 Los Angeles Games. World Athletics excluded transgender women who had gone through male puberty from female world-ranking events in March 2023 and added a once-in-a-lifetime SRY test for the female category from September 1, 2025. The Women's Tennis Association replaced its testosterone-based rule with a one-time SRY screening in July 2026. Each of these is a policy adopted to protect eligibility for the female category, in the words the pamphlet uses. The federal example is accurate in substance but overstated in form. There is a federal policy: Executive Order 14201 (February 5, 2025) makes it the policy of the United States to oppose male participation in women's sports and directs the Department of Education to prioritize Title IX enforcement, and the Departments of Education and Justice opened an investigation of Washington's school superintendent's office in April 2025. On June 30, 2026, the Supreme Court held in West Virginia v. B.P.J. and Little v. Hecox that Title IX and the Equal Protection Clause allow states to limit girls' and women's teams to biological females. But Congress has not passed a statute requiring it: the Protection of Women and Girls in Sports Act passed the House in January 2025 and stalled in the Senate, where cloture failed 51-45 in March 2025. The Supreme Court ruling says states may draw the line, not that federal law forces every state to. A reader who takes 'federal law' to mean an act of Congress that requires sex-based eligibility would be misled; a reader who takes it to mean federal policy and the governing reading of Title IX would not. That is why the rating is Mostly true rather than True. The IOC quote is accurate. The IOC's announcement quotes President Kirsty Coventry saying 'So, it is absolutely clear that it would not be fair for biological males to compete in the female category.' The pamphlet drops the opening 'So,' which does not change the meaning, and dates it correctly to March 2026. Two limits matter for the pamphlet's broader point that the measure would 'align Washington with world sports policies'. First, the sports-body policies cover elite competition: the IOC says its policy does not apply to grassroots or recreational sport, World Athletics applies its test to world-ranking competition, and the WTA rule covers its professional tour. The federal executive order and the Supreme Court ruling do reach school sports. Second, the methods differ: the three sports bodies use a one-time SRY gene screen, while I-638 asks a student's own provider to sign a statement based on anatomy, genetics or testosterone. Both points qualify the alignment argument but do not make the rated sentence false. Confidence is High because every element rests on the bodies' own published decisions, the Court's opinion and the congressional record.

How we checked

  1. Defined the claim as the exact sentence in the Argument For IL26-638 in the 2026 Washington voters' pamphlet, checked part by part for each of the four named bodies, and checked the IOC quote that follows it separately.
  2. Read each sports body's own announcement: the IOC's March 26, 2026 policy announcement (via the Olympic Council of Asia's verbatim reprint), World Athletics' March 2023 and July 2025 press releases, and the WTA spokesperson's July 2026 statement to Reuters.
  3. For 'federal law', read the text of Executive Order 14201, the Department of Education's April 30, 2025 release on Washington, the Supreme Court's June 30, 2026 opinion in West Virginia v. B.P.J., and the Congress.gov records for H.R. 28 and S. 9.
  4. Checked each policy both as of the summer of 2026, when the pamphlet argument was written, and as of October 23, 2026.
  5. Rated each part, then set the overall rating by the weakest part that matters to the sentence's meaning, the word 'law'.
