At Shoptalk 2026 in Las Vegas last week, Meta announced that affiliate marketing is coming back to Instagram and Facebook. They’ve signed up Amazon, eBay, Temu, Shopee, and Mercado Libre as partners. Creators will be able to tag products in Reels and earn commissions on sales.

Instagram actually tried this back in 2022. They ran a beta for about a year where influencers could tag products and earn commissions, then quietly shut it down. So what changed? TikTok Shop grew into a real commerce channel. One candy brand reportedly did $1.4 million in a single quarter through TikTok’s affiliate program in 2023. That kind of number gets attention in Menlo Park.

What Meta Announced at Shoptalk

The big stuff:

  • Facebook Affiliate Partnerships are live now. Amazon, eBay, and Temu in the US. Shopee across eight markets in Asia and Brazil. Mercado Libre in Latin America. When creators tag a product in a Facebook Reel or photo post, it shows up as a clickable bubble. Tap it, buy it, creator gets a cut. Commission rates are set by the brand partners. Instagram is testing the same thing, but won’t roll it out until later this year.
  • AI-generated product details in ads. Click on an ad, and Meta will now pull up reviews, specs, and product info using generative AI. Helpful for buyers, but it doesn’t change the underlying commerce infrastructure.
  • A “Buy Now” button in Facebook ads. One tap to purchase. PayPal and Stripe handle checkout at launch, with Adyen and Shopify coming. 1-800-Flowers, Fanatics, and Quince are early adopters. Brands fulfill orders themselves.
  • Shops' ads going international. Meta is opening Shops advertising in Canada, Mexico, Taiwan, Japan, Korea, the UK, and Australia. Retail media networks (Walmart, Target, Amazon) can now pick specific products from their catalogs for campaigns instead of just running broad ads.
Where This Falls Short

None of this is bad. But it’s worth being honest about what Meta actually built here versus what TikTok Shop already has.

TikTok Shop is a commerce platform with content on top. It has native storefronts, fulfillment through FBT, a structured affiliate marketplace where brands set commission tiers and creators browse open collaborations, order management, and a full seller center. The whole purchase happens inside the app.

What Meta announced is affiliate links on videos. Creators tag products, buyers click out to a checkout page run by Stripe or PayPal, and that’s the transaction. There’s no storefront. No fulfillment layer. No affiliate marketplace. Product catalog management runs through Meta’s existing business tools, which were built for advertising, not commerce.

That gap matters when brands try to run these programs at scale. Managing 200 affiliates through TikTok Shop’s seller center is a different experience than doing it through Meta’s ad tools. The tooling just isn’t there yet.

What This Means If You’re a Brand

The fact that Meta is back in this space after walking away in 2022 says something real about the opportunity. When a company with Meta’s resources decides affiliate social commerce is worth another shot, brands still wondering whether to invest should probably stop wondering.

But TikTok Shop has been building for over two years now. The affiliate ecosystem, creator tools, fulfillment partnerships, and seller infrastructure. It’s live, and it’s scaling. Brands already on TikTok Shop will be in a better position to expand to Meta’s version when it matures. Going the other direction, starting on Meta and trying to catch up on TikTok later, is going to be harder.

The other thing worth paying attention to: with affiliate commerce now running on TikTok, Instagram, and Facebook, and Amazon directly partnered with Facebook, figuring out which platform is actually driving a sale gets complicated fast. A customer sees a product on TikTok, searches for it on Instagram, and buys it through a Facebook affiliate link. Who gets credit? That’s a real question brands are going to need to answer, and it’s the kind of thing cross-channel attribution tools like halo effect measurement exist to solve.

Bottom Line

Meta clearly thinks TikTok Shop got it right. They’re building their own version. But they’re doing it with a thinner feature set and a two-year infrastructure deficit. The playbook brands are building on TikTok Shop today, the affiliate networks, the creator relationships, the fulfillment strategies, all of that transfers if Meta’s platform matures. It doesn’t work as well in reverse.

If you’re not on TikTok Shop yet, this is another signal that it’s time. If you are, keep building. The rest of the industry is catching up to where you already are.
