Meta has expanded Facebook’s affiliate program so creators can now choose from brand products and attach affiliate links directly within Reels through a self-serve flow. The feature is designed to make product promotion easier and to give creators a more direct path to commission-based monetization.  

From an arbitrage perspective, the interesting part is not the creator headline, but the inventory shift. As more creators get direct affiliate tooling inside short-form video, product placement becomes easier to scale natively on platform. That can increase competition for attention, but it also opens more partnership angles for teams that know how to source creators, package offers, and build creative that looks organic instead of ad-like.
