A group of U.S. states is seeking up to $1.4 trillion in penalties from Meta ahead of an August youth-safety trial. Multiple outlets report that the figure is outlined in court filings submitted in response to the states’ allegations that Meta designed Facebook and Instagram to be addictive for young users and misled the public about the risks to minors’ mental health.

California, Colorado, Kentucky and New Jersey are leading the case. The proceedings are scheduled to be heard in Oakland, California before U.S. District Judge Yvonne Gonzalez Rogers. One report says the states’ filings are largely kept under wraps, but a June hearing provided some details.

Meta, in a Monday court filing, says the penalty amount is unsupported by evidence and argues the calculation has no basis in fact or law. Meta also denies that it misled consumers, including by disputing the premise that “social media addiction” is an established psychiatric condition.

Separately, reporting indicates that additional states have brought related claims that are set to be heard at a different time, including a separate trial in February, depending on the claims’ scope under state laws.
