Each October, as tradition holds, the Supreme Court of the United States convenes to begin a new term. This year’s session — running from October through late June, with rulings occasionally trickling into early July — is one of the most consequential dockets the Court has assembled in recent years.

The justices have already accepted several nationally significant cases touching immigration, gun rights, presidential trade powers, gender policy in sports, agency authority, and political advocacy protections. And while the Court can add cases through the spring, the highest-impact matters are already set.

Below is a detailed look at the major cases the justices have agreed to hear — and what each one could mean for the country.

1. Birthright Citizenship and the 14th Amendment

Case Grant: December 2025

In a direct confrontation with longstanding immigration doctrine, the Court will review the legality of the administration’s order limiting birthright citizenship. For more than a century, the 14th Amendment has been interpreted to guarantee citizenship to children born on U.S. soil, regardless of their parents’ immigration status. Petitioners now argue that the executive branch cannot narrow that constitutional guarantee.

This ruling may redefine the nation’s immigration framework and stands to become one of the final — and most explosive — decisions released next June.

2. Gun Rights and Federal Drug-Use Prohibition

Case Grant: October 2025

The Court will test the scope of the Second Amendment once more, reviewing whether the federal ban on firearm possession by unlawful drug users fits within historical firearm regulations. The petitioner argues the statute fails the Court’s modern Bruen-standard test.A ruling here could clarify — or sharply narrow — who can be barred from firearm ownership under federal law.

3. Transgender Athletes, Title IX, and Women’s Sports

Case Grant: Summer–Fall 2025 (multiple petitions consolidated)

At issue is whether states and school districts may restrict transgender athletes from competing in women’s sports. Petitioners argue Title IX requires inclusion; respondents argue that competitive fairness allows sex-based distinctions.This decision will carry sweeping national implications for school athletics at both the K-12 and collegiate levels.

4. Trump Administration Tariff Authority Case

Case Grant: Fall 2025

Source: Reporting on Supreme Court acceptance of challenges to presidential tariff powers under Section 232 of the Trade Expansion Act.

The Court has agreed to examine whether Section 232 gives presidents too much unilateral authority to impose tariffs on national-security grounds. Critics argue the law violates the non-delegation doctrine by granting an open-ended power to the executive; supporters say the authority is both constitutional and essential to protecting American industries.However the justices rule, the decision will redefine presidential trade authority heading into the next decade.

5. Federal Regulatory Power & Agency Authority

Case Grants: Multiple across mid-2025

Source: Ongoing SCOTUSblog coverage of agency-authority and administrative-law petitions granted.

Continuing a years-long trend, the Court will revisit how far federal agencies may go when interpreting their statutory mandates.

Several cases question whether agencies may create broad rules without explicit direction from Congress.

The rulings could significantly reshape federal regulatory power and limit how agencies govern everything from environmental rules to workplace standards.

6. Free Speech, Nonprofits, and Political Disclosure Rules

Case Grant: 2025

Source: Litigation accepted involving compelled-disclosure requirements for nonprofit advocacy organizations.

At stake is whether the government may require nonprofit groups engaged in political advocacy to disclose membership or donor information. Petitioners argue such disclosure chills free association; states say transparency is essential to prevent political dark money.The decision may influence how advocacy groups operate leading up to the 2026 midterms.

When Will the Supreme Court Issue Decisions?

Arguments: October through April
Early Opinions: Begin appearing in November
Major Decisions: Typically arrive May–June
Final Opinions: Almost always by June 30, though the Court has occasionally stretched into early July

The justices may continue adding cases through late June, but the term’s defining disputes — especially those touching immigration, trade, and civil rights — are already on the docket.
