The fine is the latest installment of a case that dates back to June 2021. In December 2022, the regulators had determined that Facebook Marketplace violated antitrust rules. Today, it’s issuing the penalty for that violation.

“Today we fine Meta €797.72 million for abusing its dominant positions in the markets for personal social network services and for online display advertising on social media platforms,” Margrethe Vestager, Executive Vice-President in charge of competition policy, said in a statement.
