Instagram is testing an app that opens straight into Reels. The square grid spent fifteen years as your storefront. This is the clearest signal yet that the storefront is closing.
In early October, Instagram began testing an option that opens the app directly on the Reels tab — not the home feed, not following, Reels. The company is also expanding a Reels-first Facebook feed test in India. Read those two experiments together and the direction is obvious: vertical video is not a feature of the apps any more. It is becoming the apps.
The number that decides everything
Instagram’s own guidance this month noted that Reels consumption now makes up more than 50% of users’ time in the app. That single statistic explains the last five years of product decisions — Reels tab, Reels-first feeds, Reels in search, Reels boost options for livestreams, the new Reels creation guide — and it explains this one. When half your engagement sits in one format, the app’s default view is wherever the money is.
For marketers, the debate “should we do video?” ended around 2023. The live question is now organizational: can your brand produce vertical video at the cadence a Reels-first feed demands?
What a Reels-first feed changes for you
1. Your grid becomes an archive, not a storefront. For a decade, the profile grid was the first thing a new visitor saw — the proof-of-life page you designed like a shop window. In a Reels-first world, new visitors arrive on video. The grid still matters for verification and depth, but first impressions now belong to your three most recent Reels. Curate those the way you used to curate the top six tiles.
2. The hook moves from second three to frame zero. Feed-first browsing means users scroll past you in under a second. Reels-first means the thumbnail and the opening line carry the entire acquisition cost. Write the first sentence of every Reel like a headline; design the cover frame like a magazine cover. Both are cheap to fix in post and expensive to get wrong at upload.
3. Static posts are not dead — they are repositioned. Photo posts still out-perform for community, announcements and product detail with existing followers. They simply no longer carry discovery. Treat statics as retention content and Reels as acquisition content, and measure them on different axes. A brand that judges a product photo by reach will always be disappointed; a brand that judges a Reel by comment sentiment will always be confused.
4. Your production pipeline is the strategy. The brands winning Reels in 2026 are not the ones with the biggest budgets; they are the ones with a repeatable system: a weekly ideation ritual, a batch-shoot day, an editing template, and one person who owns the format. A Reels-first feed punishes brands that treat video as an occasional campaign. If you can only publish video when marketing leadership approves a concept film, you are already off the primary surface of the app.
What to do before the test rolls out to you
- Audit your last 20 Reels. Watch them with the sound off, the way most first-time viewers will. If frame zero is confusing, reshoot the opener — the topic usually survives, the packaging doesn’t.
- Set a floor, not a ceiling. Decide the minimum weekly Reels cadence you can sustain forever — three is a common, honest number — and protect it before you chase spikes.
- Repurpose ruthlessly. One idea shoots as a Reel, screenshots as a carousel, quote-posts to Threads, and clips to TikTok and Shorts. Distribution multiplies what a single shoot produces; that is how small teams keep up with a video-first platform without a video crew.
- Keep the grid tidy anyway. The profile is still where a curious viewer goes to decide if you are real. The grid is now your about page, not your homepage. Design it like one.
The honest caveat
Instagram has tested the Reels-first open before, in quieter form, and rolled some of it back. This test is broader, and the 50% figure behind it is not going down — but tests are not promises. The strategic bet is still safe: vertical video is where the attention is, whether or not the app opens on that tab. Build the system, keep the grid tidy, and let the algorithm shuffle the furniture.
