The federal cases that actually moved in 2026, what each one decided, and where to read the record yourself. Updated with the rulings that landed after the original list was published.
Federal courts are where the biggest legal battles unfold—billion-dollar antitrust fights, high-profile criminal prosecutions, and constitutional showdowns that shape American law.
But until recently, accessing these cases meant navigating PACER's clunky interface, paying per-page fees, and reading dense legal documents without any help understanding what they mean.
That's changing.

The list above was written before several of these cases moved. Here is where each one stands, with the coverage that goes deeper.
The Mangione prosecution is no longer a capital case. Judge Garnett dismissed two counts on January 30, 2026, and prosecutors declined to appeal. Trial is set for October 2026. See why the death penalty was dismissed.
The FTC's monopolization case against Amazon is set for trial in October 2026 before Judge Chun in Seattle. The separate Prime subscription case settled for $2.5 billion in September 2025, which is a different case entirely. See FTC v. Amazon.
The Google search case moved to the D.C. Circuit. Judge Mehta found liability in 2024, imposed conduct remedies rather than a Chrome divestiture in September 2025, and both sides appealed. See the search monopoly appeal.
The Combs prosecution ended in acquittals on racketeering and sex trafficking and convictions on Mann Act counts. The Second Circuit heard the sentencing appeal in April 2026. See the Sean Combs case.
Two cases that were not on the original list turned out to matter more than most that were. A Manhattan jury found Live Nation and Ticketmaster liable on every claim the plaintiff states tried, covered in the Live Nation litigation. And the Supreme Court overruled a 1935 precedent on removal protections in June 2026, covered in Trump v. Slaughter.
Do not. Watch the dockets instead.
