Does Adobe commerce cloud offer a Multi-vendor marketplace extension?

Adobe Commerce Cloud does not provide a marketplace extension. However, you can use Webkul's Magento 2 Multi Vendor Marketplace Extension with Adobe Commerce Cloud to get the feature. 

The Marketplace Multi-Vendor Module is compatible with Magento 2 Enterprise edition. It provides a marketplace feature where vendors can register their accounts, add their products, manage orders, etc. 

Additionally, there are many prebuilt Magento 2 Marketplace Add-ons available, using which you can achieve most of the trending feature out of the box.
