India’s retail media boom now runs on fulfilment, not discounts

India’s retail media machine loves its own mythology. Every festive cycle arrives with the same chest-thumping promises: bigger banners, smarter algorithms, deeper discounts. Yet when you strip away the performance dashboards and seasonal theatrics, the real engine behind the market’s growth is something far less romantic.

Retail media in India is projected to grow 21.9 percent in 2025, outpacing both paid search and social, and most of that money is quietly flowing to the platforms that can deliver the product fastest, and not necessarily cheapest. The fastest-growing ad channel in India is now shaped by something the industry doesn’t often say out loud: fulfilment speed.

The country’s largest platforms are effectively retail media companies with commerce attached. Amazon, Flipkart and Myntra together reported around ₹15,500 to ₹15,600 crore in FY25 advertising income, growing roughly 26 percent year on year. Amazon alone contributed ₹8,340 to ₹8,370 crore; Flipkart Internet added more than ₹6,317 crore; Myntra took the combined number to ₹7,232 crore.

These aren’t auxiliary revenue streams. These are the pipes directing India’s highest-intent budgets. With digital ad spending overtaking TV in 2025, retail media has become the country’s default closed-loop channel. In theory, brands are chasing “visibility”. In reality, they are chasing platforms that can guarantee delivery before the customer changes their mind.

Quick commerce has made this shift impossible to ignore. The sector hit US$5.38 billion in 2025, with ARPU in the US$137 range, user penetration nearing 2.7 percent and rising toward 4 percent by 2029. India already has about 26 million quick-commerce users, projected to reach 60.6 million by 2029 with ARPU pushing past US$161. That is enough scale for ad monetisation to be a serious business.

Blinkit, Zepto and Instamart don’t sell themselves as “content destinations”. They sell themselves as the fastest, densest fulfilment grids in urban India. Proximity has become an advertising product. The ad works because the delivery does.

Senior marketers have been the first to acknowledge this shift. Venugopal Nair, Chief Business Officer at Fixderma, says, “Rapid fulfillment is our competitive moat.” He explains that the dense SLA (Service-Level Agreement) coverage of quick commerce satisfies instant-gratification demand in a way traditional e-commerce simply cannot, allowing the brand to “drive conversion without diluting brand equity through deep discounting.”

But Nair adds an equally important constraint the platforms rarely admit. Fixderma has not aggressively shifted spend into quick commerce because, as he puts it, “The model’s inherent limitation—restricted inventory depth per pin code—leads to frequent stock-outs. Until fill rates stabilize, increasing media spend poses a risk of wasted impressions on out-of-stock SKUs.” In other words: speed works, but only if the shelf behind it can keep up.

Agencies corroborate this with hard numbers. Shradha Agarwal, Co-founder and Global CEO of Grapes Worldwide, says that across her client work, “same-day or next-day delivery typically amplify conversions by 20–35%, and during high-intent festive periods that jump can touch as high as 40%.” Price cuts, she points out, don’t show comparable lift unless matched with speed. Smaller drops of five to ten percent “do not create much of a difference unless they’re supported by quicker delivery.”

Consumers increasingly view fast delivery as a proxy for reliability, especially in beauty, electronics and gifting. Agarwal says brands are already shifting budgets toward platforms with stronger SLA coverage, and that placements advertising two-hour or same-day delivery “naturally command a premium” and get locked early.

She expects CPMs to rise, attribution windows to shrink and fulfilment to keep migrating from backend hygiene to something she calls “a visibility booster that brands are willing to invest in.”

If agencies are the early warning system, operations-side players are the ground truth. A Fynd spokesperson points to their Festive Report 2025, which has a single statistic that explains why India’s retail media market has turned into a fulfilment arms race. When orders reached customers within zero to three days, RTOs were at 23 percent. Once delivery went beyond three days, RTOs shot up to 77 percent. Speed doesn’t just influence conversion. It prevents attrition.

The spokesperson adds that store-led fulfilment jumped from 29 percent last year to 51 percent this season, marking the first time stores and warehouses contributed almost equally. Around 4 percent of orders were even hopped between stores and warehouses to salvage potential losses. These aren’t marketing optimisations. These are operational contortions driven by the need to maintain SLA-eligible inventory through the entire media cycle.

This also reconfirms the seasonal concentration of demand. Myntra owned 48 percent of festive orders and Flipkart held 41 percent, giving the two almost 89 percent of the season’s share. But the performance edge within this duopoly increasingly comes from delivery reliability. Amazon, for instance, brought returns down from 17 percent to 8 percent and lowered RTOs from 6 percent to 2 percent by tightening operational discipline.

That reduction in friction loops straight back into ad efficiency. Every percentage point of reduced returns is effectively money returned to the performance budget, not the warehouse. The spokesperson notes that platforms investing in speed and post-purchase reliability are gaining the competitive edge, and that brands are beginning to optimise not just for pricing and visibility but for “operational performance and delivery experience.”

Media-led agencies see the same behavioural pattern on the frontlines. Nitin Kumar Kosari, AVP eMarkets at LS Digital, says that SKUs with same-day or next-day delivery “tend to see a 10–20% higher conversion rate compared to standard 2-4 day SLAs,” and that the uplift “can rise to 20–30%” during festive peaks.

He has also seen lower product-page dwell time on fast-delivery SKUs, as shoppers decide faster when the delivery promise is credible. Kosari says brands have already begun shifting budgets toward Amazon Prime clusters, Flipkart Minutes zones, quick-commerce nodes and Myntra Now, with time-sensitive categories like health and wellness seeing 15 to 25 percent stronger ROAS on fast-delivery listings. CTR is consistently higher when the badge promises speed.

Even without explicit SLA-priced media products, shopper behaviour is creating a natural premium around velocity. Kosari adds that inventory planning cycles have shrunk to barely a week so brands can ensure SLA eligibility before campaigns go live.

Taken together, the numbers and voices point to the same conclusion. India’s retail media ecosystem has shifted from discount-driven spikes to fulfilment-driven outcomes. Visibility can still get attention. Price can still trigger interest. But speed is now the variable that determines whether intent survives long enough to convert.

Stores, warehouses, delivery hubs and inventory density have become the country’s real media infrastructure. Platforms are not just selling audiences. They are selling promise-delivery alignment.

This shift also broadens the field beyond the predictable Amazon-Flipkart rivalry. Quick commerce has emerged as an alternative organising principle for performance marketing. Blinkit, Zepto and Instamart have built fulfilment grids that double as high-intent media surfaces. The ability to deliver within minutes is no longer a grocery gimmick. It is an advertising edge. And brands, quietly but steadily, are following the speed.

Retail media will keep expanding in India as platforms consolidate delivery capacity and as brands recalculate the performance value of reliability. The platforms that can guarantee speed will keep absorbing more festive and year-round budgets. The ones that cannot will fall back on louder marketing and heavier discounting. Fulfilment, not pricing, has become the differentiator. And in the end, the ad is only as strong as the delivery truck behind it.
