Kids Online Safety Act (KOSA)

KOSA is proposed federal legislation that would impose a 'duty of care' on covered online platforms to mitigate specified harms to minors and authorize the Federal Trade Commission to enforce it, which critics warn would push platforms like Reddit toward age verification and content restrictions. The Senate passed KOSA 91-3 on July 30, 2024, but it failed to reach a House floor vote before the 118th Congress ended, nullifying its progress. It was reintroduced in the 119th Congress in 2025 but has not been enacted. Section 230 of the Communications Decency Act is the broader legal backdrop against which KOSA's platform-duty provisions are debated. The bill remains one of the most-watched US proposals affecting general social platforms.
