Threads Ads Grow Up: Carousel, Catalog and App Ads Change the Creative Rules

Threads ads are no longer a text-only experiment. In August 2026 Meta is testing three new ad formats on the platform — carousel ads, Advantage+ catalog ads and Advantage+ app ads — and has opened Threads placements to advertisers who don't even have a Threads profile. Combined with the move from beta to general availability in most markets, this is the moment Threads stops being a curiosity and becomes a real full-funnel placement. The catch: the creative rules that made Threads cheap are exactly the ones most advertisers will abandon as soon as the new formats arrive.

What Meta actually changed on Threads in August 2026

The August 8 roundup from SocialBee, which tracks Meta's advertising updates week by week, lists three Threads-specific changes for the month:

• Meta is testing carousel ads on Threads.
• Meta is testing Advantage+ catalog ads and Advantage+ app ads on Threads.
• Meta now allows brands without a Threads profile to use their Instagram or Facebook ad account to run Threads ads.

AdAdvisor's August changelog adds the second signal: Threads ads have moved from beta to general availability in most markets, and the Meta Ads changelog compiled by AdMake AI confirms the global rollout completed during the current quarter. That matters more than it sounds — beta placements come with forgiving auction treatment and polite warning labels; general availability means the platform is now a line item advertisers are expected to manage like any other.

The formats themselves are not new to Meta — carousels and catalog ads have run on Instagram for years. What's new is that they are landing on a platform whose audience behaves differently, and that difference is the entire story.

Why the formats matter: Threads stops being a top-of-funnel-only channel

Until August, a Threads strategy meant image or video ads aimed at reach and engagement. That's a discovery play. The new formats change the funnel math:

The strategic read: Threads is becoming a channel where you can run the same campaign architecture you run on Instagram — but with a cheaper CPM and a more conversational audience. For ecommerce, the catalog ads opening is the most important item on the list. Dynamic retargeting on a placement that still costs 30-46% less than Feed is a Q4 arbitrage that very few advertisers have priced in yet.

The creative mismatch is still the dominant variable

Here is the part that will not change with the new formats, and it is worth being blunt: the benchmarks that make Threads attractive exist because most advertisers run the wrong creative there.

An AdRiseLab study of roughly 140 agency-managed accounts (May-June 2026) found Threads CPMs 30-40% below Instagram Feed across verticals, with CTRs 43-113% higher and CPCs roughly half — ecommerce CPCs averaged $0.36 on Threads vs $1.22 on Feed. AdAdvisor's changelog reports Threads CPMs around 46% below Facebook/Feed levels. Those numbers are real, and they are also a supply-demand artifact: at under 0.04% of total Meta ad spend, almost nobody is buying the placement.

The same study is explicit about what happens to advertisers who treat Threads as "Instagram #2": repurposed Instagram creative systematically underperforms, the algorithm down-weights it, and the cycle keeps demand artificially low. That's the self-reinforcing loop that keeps the arbitrage alive — and it is exactly the loop that breaks when advertisers start running threads-native creative at scale.

At Mintec, when we put a client on Threads we run the placement manually and isolated for the first two weeks, with creative adapted for the feed: a question or contrarian statement as the hook, copy doing the heavy lifting, and the visual as support rather than star. The pattern across verticals is consistent — conversational creative outperforms polished Instagram-style creative on Threads by a wide margin, which is why the CPM gap persists. As the new formats scale, the teams that adapted creative early will be the ones enjoying the cheap CPMs; everyone else will deliver the inventory to them at a discount.

The August decision framework: who should test what, now

General availability plus new formats plus Q4 planning is a rare combination — usually you get one of those at a time. Here is how we would prioritize, in order:

1. Ecommerce with a healthy catalog (Advantage+ catalog first). Enable Threads inside your existing Advantage+ catalog campaign, or open a manual Threads placement with catalog ads. Budget 10-15% of the catalog campaign's budget. The dynamic retargeting value on a 40%-cheaper CPM is the strongest risk-adjusted test available this month.
2. Service businesses and educators (carousel first). A three-to-five card carousel that walks through a customer journey — problem, comparison, proof, offer — with a text-first hook on card one. This is where Threads' conversational audience pays off.
3. Apps (Advantage+ app ads, small test). The install cost story on Threads is unproven at scale; test with a budget ceiling and judge on event quality, not just install price.
4. Everyone else: keep image/video, but adapt. The cross-account eligibility change means you can test Threads without building a profile first. Isolate the placement, adapt the creative, and let the auction tell you if the audience fits your offer.

Two things we would not do. We would not re-run Instagram creative as-is on Threads and judge the channel by the result. And we would not wait until October to "strategize" the test — general availability means demand is already rising, and the Q4 auction will normalize Threads CPMs faster than the previous arbitrage windows did on Stories or Reels.

The opinion underneath all of this

The Threads ad story in 2026 is a story about format timing, not about the platform's audience. The audience was always there — 400 million monthly actives and a text-first culture that rewards opinions. What changed in August is that the formats finally match what advertisers know how to run. That's an opportunity, but it's a fleeting one: the cheap CPMs are a subsidy for early testing, and the subsidy exists because creative quality on Threads is still low.

The brands that win the next two quarters on Threads will be the ones that treat the new formats as new creative problems, not as new placements for old assets. Text-first hooks, conversational copy, catalog quality that stands on its own — those are the rules that made Threads cheap, and they are the rules that will make it work once the window closes.

If you want the mechanics of measurement, our breakdown of Threads ad costs and the arbitrage window covers the numbers in detail, and the Threads API creative pipeline explains how to test creative at scale without burning the media team's week. For B2B teams deciding whether Threads fits their demand-generation model, the Threads lead-gen playbook is the reference. And before the catalog formats go live on your account, the Advantage+ creative automation notes are the right starting point for understanding how Meta will treat your assets there — the same logic that applies to the placement cost tradeoffs we covered for Instagram Reels vs Feed.
