"Shares of eBay rose 12% after Meta announced the integration of eBay listings on Facebook Marketplace, beginning in Germany, France, and the United States. The integration allows eBay sellers to reach a larger audience while transactions will remain on eBay, preserving platform integrity. Meta's action follows a fine of 797 million euros from the European Commission for unfair competition practices related to Marketplace. Meta continues to appeal the European Commission's ruling, claiming no harm to competitors exists, citing the success of other platforms like eBay."
