Ninth Circuit Rejects Roblox's Arbitration Demand in Kids Safety Suit

The Ninth Circuit denied Roblox's motion to compel arbitration in a child safety class-action lawsuit.

On September 3, 2026, the Ninth Circuit Court of Appeals issued a significant decision rejecting Roblox Corporation's motion to compel arbitration in a class-action lawsuit filed by parents. The suit accuses Roblox of deceptive business practices, specifically alleging that the company misled parents about the safety of its platform for children. Among the concerns raised in the lawsuit are claims of inappropriate behavior by other users, including grooming attempts targeting minors.

The court’s ruling focused on Roblox’s conduct during litigation. It found that Roblox waived its right to enforce arbitration by engaging in nearly a year of litigation on the case's merits before attempting to invoke the arbitration clause, a move the court described as inconsistent and unfair. As the Ninth Circuit stated, "A party cannot ask the district court to dismiss a complaint on the merits, holding in reserve a claimed right to arbitrate that will be exercised only if it does not like the district court's decision."

This outcome signals increasing judicial scrutiny on arbitration clauses in consumer technology agreements, especially those involving parental and children’s rights claims. It limits the ability of companies like Roblox to unilaterally redirect disputes away from courts once significant litigation has occurred.

Roblox's stock price stood at $41.51 on the date of the ruling, reflecting a market capitalization of nearly $30 billion amid ongoing scrutiny of its business practices. While this case is focused specifically on safety and consumer protection, its implications extend broadly to how courts view arbitration clauses in tech agreements, potentially influencing future class-action lawsuits against online platforms.
