Blinkit vs Zepto vs Instamart for Brands 2026: Reach, Margins, Ads

Blinkit, Zepto and Swiggy Instamart run the same model: they buy your stock on purchase orders at a margin below MRP, hold it in dark stores, and sell you visibility on top. None of them publishes a rate card, so a brand comparing the three is comparing negotiated margins, reported operational charges, ad economics and store footprints, not price lists. As of September 2026 this guide puts the three side by side using the figures collected in our Blinkit, Zepto and Instamart fee guides, marks what is official and what is agency observation, and ends with which platform a brand should pitch first.

Every margin and charge below is a range from third-party or brand-side sources unless marked official. Your vendor agreement is the only binding document.

Blinkit vs Zepto vs Instamart at a glance

Which takes the smallest margin?

By the reported ranges, Blinkit and Zepto sit close together in the mid-teens on MRP for packaged FMCG, and Instamart a few points higher; brands consistently describe Instamart as the most expensive of the three on margin, though not always on ads. The official signal from Swiggy points the same way: Instamart's blended take rate rose from 12.2% in Q1 FY24 to over 15%, with management targeting 20% to 22%, and Swiggy says advertising is the main driver. That take rate is platform-wide, not your rate, but it tells you the pressure is shifting from margin to ad spend.

The spread is Rs 7 a unit on a Rs 100 pack, and every one of those inputs is negotiable. Strip Instamart's inwarding and packaging lines, which many PO brands negotiate away, and its contribution rises to Rs 23, level with Zepto. The lesson from all three guides is the same: margin first, ad efficiency second, operational charges third, and a brand with under 50% gross margin on MRP has very little room on any of them. Our quick commerce margin calculator runs your own numbers.

Which has the most reach?

Swiggy is the only one of the three that puts a figure where a brand can read it: 1,171 dark stores across 131 cities at the end of June 2026. Eternal reports Blinkit's store count in its quarterly results, and press coverage through 2026 has put Blinkit ahead on store count and order volume in the big metros, but the seller portal itself publishes nothing. Zepto's brand portal publishes no store count; its DRHP describes the business but not a per-city footprint.

Reach cuts two ways on quick commerce. More stores means more shelves, and a wider footprint like Instamart's 131 cities means a national brand is servicing many small purchase orders in cities where its own distribution may be thin. The fill rate target on all three is 95% or better, judged on the blended number, so a brand that fills 98% in Bengaluru and 80% in Lucknow is an 89% brand. A smaller footprint with full shelves earns the next PO; a bigger one with gaps does not.

How do the ad economics compare?

Ads are not optional on any of the three; a ten-minute app shows very few products and most sales come from the first rows of search. Zepto is the only platform with an official number: Rs 1,635.7 crore of ad revenue in FY26 from 2,468 brand partners, up 151% in a year, which averages about Rs 66 lakh a brand, skewed by large FMCG houses. The Redseer research in the same filing puts quick commerce return on ad spend at 5x to 8x, the closest thing to an independent benchmark.

The formats and price points reported by agencies differ in shape. Blinkit's Product Booster takes 80% to 90% of most budgets at Rs 2 to Rs 15 a click, with Rs 25,000 to Rs 50,000 a month for beginners. Zepto's search ads run Rs 3 to Rs 20 a click, homepage banners on a CPM basis with about Rs 1 lakh minimum, "Swap and Save" placements that intercept a competitor's add-to-cart, and Rs 50,000 a month suggested for performance campaigns. Instamart sells quarterly brand packs of Rs 8 lakh to Rs 10 lakh with a three-month commitment alongside auction placements, and can run one campaign across food delivery and Instamart. The budget rule of thumb on all three is 8% to 15% of platform sales; note that Zepto's dashboards report sales on MRP, which flatters ad returns, so model on MRP throughout.

Which is easiest to get onto?

None is open. All three route you to a Category Manager who acts as a buyer, and all three want the same things: proof of sell-through elsewhere, a short hero range of 5 to 10 SKUs, impulse-friendly price points, product-forward images and margin headroom. The documents are identical, GSTIN, PAN, bank, FSSAI for food, trademark or authorisation, GS1 barcodes, and an APOB for each state where the platform's warehouse holds your stock; APOB is the one that blocks purchase orders if missed.

Reported timelines differ. Blinkit's 2 to 4 weeks with clean documents is the shortest; Instamart's 15 to 25 business days is similar; Zepto's 3 to 6 weeks for a single city, with verification alone reported at 30 to 45 days, is the longest. Instamart's launch package starts in Bengaluru with about 50 units per SKU, which suits a brand with a southern base. Our onboarding guide covers the steps and the rejection reasons.

Verdict by brand type

Most brands we manage are on all three within a year, but rarely start on all three. The first agreement sets the anchor for every renewal on that platform and, because category teams talk to the same brands, for the other two as well. Win one shelf with a full fill rate and velocity data, then use that data to negotiate the next.

FAQ

Which is cheapest for brands: Blinkit, Zepto or Instamart? By reported ranges, Blinkit and Zepto sit in the mid-teens on MRP for packaged FMCG and Instamart a few points higher. On the Rs 100 worked example the contribution spread is Rs 7 a unit, and every input is negotiable.

Do any of them publish a commission rate? No. All three negotiate a margin on MRP per brand and category. Zepto's DRHP and Swiggy's quarterly reports publish platform-level figures, not brand rates.

Which has the most dark stores? Swiggy publishes 1,171 Instamart stores in 131 cities as of June 2026. Eternal reports Blinkit's count in its results; Zepto publishes none on its brand portal.

How much should I budget for ads? Agency guidance on all three is 8% to 15% of platform sales, with Rs 25,000 to Rs 50,000 a month as a starting point. Zepto's own filing shows ads averaging about Rs 66 lakh a brand a year, skewed by large houses.

Is there a deposit? Reported but not published: about Rs 25,000 on Blinkit (per SKU per cluster on SOR) and Zepto (refundable, some brands), and a Rs 30,000 plus GST per SKU launch package on Instamart. All are largely returned as ad credit.

Should I launch on all three at once? Usually not. Fill rate is judged per platform and the first agreement anchors renewals; win one shelf, then use the velocity data to negotiate the next.

Getting the first quick commerce shelf right

Blinkit, Zepto and Instamart differ by a few points of margin and a lot of operational detail, and none of it is written down where you can read it before the negotiation. If you want a team that prepares the pitch, negotiates margin with velocity data, runs NPI, PO servicing and ads, and reconciles every settlement against goods receipt notes, see our quick commerce account management service. We cover all three platforms, and the audit through our quick commerce service page starts with whether your gross margin can carry the model at all.
