Starting September 2026, matching usernames between Threads and Instagram are no longer required to run ads. It sounds like a settings change. It is actually a divorce filing.
Meta announced that advertisers no longer need a matching Instagram username — or in some rollouts, an Instagram account at all — to run Threads campaigns. The requirement that Threads advertising inherited at launch was always scaffolding: to buy ads on Threads, you essentially had to be Instagram wearing a hat. That scaffolding is now coming down, and it tells you more about where Meta is taking Threads than any feature announcement this year.
What exactly changed
The mechanics first. From September, the username-matching requirement between Threads and Instagram profiles was dropped in the ads setup. Advertisers can set up Threads campaigns without the account-linking gymnastics that made early Threads ad buys awkward: the mismatched-handle workaround, the “we own @brand but not @brand_th” email chains, the campaigns that quietly failed review because the two identities did not line up.
For small businesses, this is the most consequential Threads change since the platform opened its ad product: fewer accounts to manage, fewer rejections to chase, and a plausible path to running a Threads-only campaign for a Threads-only audience.
Why the requirement existed in the first place
Threads launched in July 2023 bolted to Instagram identity — the signup flow was literally “continue as [your IG handle]”. The ad system inherited that coupling because it was convenient: Meta could reuse Instagram’s advertiser infrastructure, billing identities and review systems without building anything new. The coupling also served a strategic purpose. It kept advertisers treating Threads as an Instagram extension, which kept budget flowing to Threads before the audience was large enough to defend its own line item.
Why it is disappearing now
Three forces are behind the split, and they compound:
- Threads has grown up as a product. Live chats with reactions and hand-raising, quote posts with visual treatments, performance awards for posts, and Meta AI appearing in replies (@meta.ai tagging) have made Threads a distinct behaviour, not a Twitter-shaped side project. Advertisers increasingly want to buy that behaviour on its own terms.
- Identity decoupling is already happening. Creators and brands have long complained that Threads inherits Instagram’s persona. You cannot be a text-first account on Threads while your Instagram is a photo portfolio. Every month, more accounts build Threads audiences that do not map to their Instagram graph — and every one of those accounts is friction in the ad system.
- Meta’s own words give it away. Meta frames the change as recognition that “Threads operates as its own distinct platform now.” Companies do not untether ad products from their parent identity unless they intend to sell the child product separately, price it separately, and report on it separately.
What marketers should do
If you are already on Threads, treat Q4 2026 as the cheap window. Ad products in the “now available to everyone” phase are historically under-priced relative to their performance — the same dynamic that made early Instagram Stories and early Reels placements a bargain. Threads’ conversation format rewards the kind of native, low-gloss creative that brands are still nervous about; be the brand that experiments while CPMs are soft.
If you are not on Threads, the username decoupling removes the last structural excuse. You can now build a Threads presence that is text-first, opinionated and native to the platform, without it being held hostage to an Instagram handle you bought in 2012.
The watch item for 2027: a separate Threads placement in the Meta Ads Manager buying flow, with its own auction dynamics and its own reporting. Once the ad product is fully independent, the strategic separation is complete — and Threads becomes a platform you decide to be on, not a checkbox under Instagram.
