A case-by-case look at the Supreme Court’s October 2026 oral arguments

Key takeaways

The U.S. Supreme Court heard six cases in its October 2026 sitting, which opened the 2026-27 term on October 5, 2026:

  • Suncor Energy v. Boulder County (state-law climate lawsuits): justices appeared divided.
  • Salazar v. Paramount Global (online video privacy): justices appeared likely to side with the subscriber.
  • Anderson v. Intel (401(k) investment lawsuits): several justices favored Intel’s position.
  • Johnson v. United States Congress (veterans’ benefits challenges): justices saw flaws on both sides.
  • Department of the Air Force v. Prutehi Guåhan (environmental challenge over munitions detonation on Guam): justices worried about shutting the community group out of court.
  • Beaird v. United States (federal sentencing guidelines): little change expected.

Decisions are expected by the end of June 2027. November arguments begin November 2.

Overview

The Supreme Court opened its 2026-27 term on October 5, hearing six cases over two weeks and turning away hundreds of other petitions on day one. The stakes for the cases the Court did take up are significant: billions in potential climate liability, the rules for online tracking, and how Americans’ retirement savings are managed. No rulings yet, but oral arguments offer strong clues. Here’s what each case is about, how the justices sounded, and what could come next.

Suncor Energy v. Boulder County: Climate lawsuits

The case: Boulder sued Exxon Mobil and Suncor under Colorado law for damage from floods, wildfires and drought it blames on climate change. Colorado’s Supreme Court let the suit proceed.

The question: Does federal law block state-law climate suits, and can the Supreme Court even hear this case now?

At argument:

  • The Court seemed split. Chief Justice John Roberts worried about unlimited copycat suits. Boulder says it isn’t trying to regulate emissions, which federal law controls, only to recover the cost of climate damage. Roberts and Justice Kagan were skeptical, suggesting big damage awards would pressure companies to cut emissions anyway, making it regulation by another name.
  • Liberal justices questioned whether the Supreme Court has jurisdiction to step in yet, since the case is still at an early stage in Colorado courts. If not, the Court could dismiss it without ever deciding whether climate suits like Boulder’s are allowed, leaving that question for another day. Justice Samuel Alito is recused.

What it could mean: Dozens of similar suits hang on this case. A win for the companies could end them nationwide; a jurisdictional dismissal would leave the fight in state courts for now.

Salazar v. Paramount Global: Online video privacy

The case: A 247Sports newsletter subscriber says Paramount used Meta’s tracking pixel to send his Facebook ID and viewing history to Facebook without consent.

The question: Does the 1988 Video Privacy Protection Act, passed after Judge Robert Bork’s rental history leaked, cover subscribers to any product from a video provider, or only video customers?

At argument:

  • The justices appeared poised to side with Salazar.
  • Justice Brett Kavanaugh probed whether that would flood streaming businesses with lawsuits; others noted companies can simply get consent.

What it could mean: More class-action exposure for publishers and ad platforms that use tracking tools, though a ruling for Salazar wouldn’t by itself make Paramount liable.

Anderson v. Intel: 401(k) investments

The case: Intel employees say plan managers imprudently put retirement savings into hedge funds and private equity, raising fees and lowering returns.

The question: The workers say Intel’s investment picks underperformed. To avoid having their case thrown out early, is it enough to point to popular funds that did better? Or must they find a truly comparable fund, one with similar goals and risk, that beat Intel’s?

At argument:

  • Several justices backed the benchmark standard, and the workers’ lawyer faced skeptical questions.
  • The Trump administration previously supported Intel’s position

What it could mean: If Intel wins, employers will have an easier time getting these lawsuits thrown out before trial. Less legal risk could also lead more employers to offer private equity in 401(k)s, a goal the Trump administration is already pushing.

Johnson v. United States Congress: Veterans’ benefits

The case: Veteran Floyd Johnson’s disability rating was cut from 80% to 10% under a law capping benefits for veterans jailed more than 60 days. He calls the cap unconstitutional.

The question: Must constitutional challenges to veterans’ benefits laws go through the VA’s appeals system, or can regular federal courts hear them?

At argument: Several justices saw flaws on both sides and struggled with where to draw the line. Both Johnson and the Justice Department had asked the Court to resolve a split among appeals courts.

What it could mean: It decides which courthouse door veterans use, and the VA’s own appeals board can’t strike down an act of Congress.

Department of the Air Force v. Prutehi Guåhan: Bombs on a Guam beach

The case: The Air Force has detonated old munitions on a Guam beach since 1982. Prutehi Guåhan, a Guam community group, says the Air Force renewed its permit without required environmental review, above an aquifer serving over 80% of the island.

The question: Is a permit-renewal application a “final agency action” that can be challenged now?

At argument: Justice Clarence Thomas called the dispute odd, but justices across the spectrum worried a ruling for the Air Force could shut Prutehi Guåhan out of court entirely.

What it could mean: The Air Force warns the lower-court ruling reaches far beyond Guam. The decision will set when communities can challenge federal projects under environmental law.

Beaird v. United States: Sentencing rules

The case: Kendrick Beaird, a convicted felon, pleaded guilty to illegally possessing a gun in Texas and was sentenced to six years in federal prison. His gun had a 17-round magazine, and the Sentencing Commission’s official commentary counts anything over 15 rounds as a “large capacity” magazine, pushing his recommended sentence higher. Beaird says that definition goes beyond the guideline itself.

The question: The Commission writes official notes that define terms in its rules, like what counts as a “large capacity” magazine, and Congress never signs off on them. The Supreme Court said in 1993 that judges must follow these notes, but it has since cut back on that kind of rule. Do judges still have to follow them?

At argument: The Justice Department sided with Beaird, so the Court appointed an outside lawyer to defend the ruling. Observers expect little change.

What it could mean: Low on headlines, high on impact. Appeals courts are split on how much the commentary counts, and it shapes sentencing ranges nationwide.

Conclusion

The October cases are less flashy than last term’s blockbusters, which touched on major constitutional questions, but this docket is still significant. Early signals point to a Court wary of open-ended business liability but protective of access to the courthouse door. The justices return for November arguments on Nov. 2, and decisions in the October cases are due by the end of June 2027.
