Meta Platforms Inc. is prying open its previously guarded Facebook Marketplace platform to a swathe of classified ads rivals, in a renewed attempt to comply with a landmark European Union antitrust order that was accompanied by a €798 million ($829 million) fine.

Following the EU Commission's antitrust fine in the millions, Meta will in future display competing ad providers on Facebook, but is still appealing.

Meta Platforms will allow rival classified ads service providers to post listings of their ads on Facebook Marketplace, the company said on Thursday, three months after it was hit with a 797-million euro ($828 million) EU antitrust fine for giving its own service an unfair advantage.

Meta Platforms is rolling out a new partnership program to appease European Union antitrust regulators that will let rival classified advertisement companies list ads on Facebook Marketplace in the EU.

Meta Platforms (META) will allow its competitors to list their ads on Facebook Marketplace, Reuters reported Thursday.
