Bay shares experienced a significant boost, soaring 12% on Wednesday, following Meta’s announcement to expand Facebook Marketplace by allowing some eBay listings to appear on the platform. This strategic move aims to extend eBay’s reach and provide a seamless experience for buyers and sellers.

Meta is testing eBay listings on Facebook Marketplace in the US, Germany, and France. The company said in a post on Wednesday that it’s making the change to comply with last year’s antitrust order by the European Union, though it continues to appeal the decision.

Meta said on Wednesday it would launch a test in Germany, France and the United States that will enable buyers to browse listings from eBay on Facebook Marketplace and then complete their transactions on eBay.
