India's Cola War Has Become a Refrigerator Arms Race: Why Campa, Coke and PepsiCo Will Install One Million Chillers in 2026

India's cola war is no longer being fought on the shelf. It is being fought on the appliance underneath it.

Reliance's Campa Cola brand — relaunched in March 2023 from a 1970s Indian brand the conglomerate bought for around ₹22 crore — generated ₹47 billion (around $493 million) in gross sales in the year to March 2026, according to a Reliance Industries investor presentation released last month. That makes Campa the country's fourth-largest carbonated soft-drinks brand with double-digit market share in several states, and the first credible domestic challenger to the Coca-Cola-PepsiCo duopoly in three decades. Coca-Cola India posted ₹51.7 billion in revenue in the year to March 2025, according to filings collated by Tofler. The gap between the incumbent and the disruptor has narrowed to a single-digit growth quarter.

What is more striking is what the three players are doing with the cash. They are building refrigerators.

The chiller is the shelf in India

At PepsiCo's largest Indian bottler Varun Beverages, chairman Ravi Jaipuria told the April 27 earnings call that Reliance, Coca-Cola and Varun are collectively installing close to half a million visi-coolers a year across Indian retail outlets. Independent retailers are buying another 400,000 to 500,000 cooling units on their own account, adding up to roughly one million chilling units entering the Indian trade every year — most of them into stores that previously had no refrigeration capacity at all.

India's commercial refrigeration market, the bulk of it driven by beverage visi-coolers, was worth $2.8 billion in 2025 and is forecast to reach $3.9 billion by 2034, according to IMARC Group estimates. Mohit Sud, group president for Unitary Cooling Products at Blue Star Ltd., told Bloomberg the segment is "growing faster than Blue Star's annual growth." Voltas (a Tata Group company), Haier Appliances India and Western Refrigeration are the other principal beneficiaries.

In developed markets, the refrigerator is a kitchen appliance. In India, the refrigerator is distribution infrastructure — owned by a beverage brand and rented to a retailer in exchange for shelf exclusivity. The fight to install the next million chillers is a fight to lock retail outlets into a beverage relationship for the five-to-eight year operating life of the cooler.

How Campa rewired the price floor and forced a distribution war

For thirty years, Coca-Cola and PepsiCo controlled the Indian carbonated category through a single architectural trick: install branded chillers, supply them with branded SKUs, and prevent independent kirana stores from displaying any other soft drink at the cold point of purchase. The fridge was both shelf and exclusivity contract. Campa broke that lock by attacking the price point underneath it. The 200ml Campa bottle sells for ₹10 — about 12 US cents — roughly half the price of a 250ml Coke or Pepsi unit.

Cheap product alone would have produced a flash promotion, not a category event. What turned Campa into a structural problem for the incumbents was the simultaneous decision to invest in visi-cooler installations at scale alongside the price cut. Reliance is not just selling a cheaper SKU into existing fridges. It is rolling out its own fridges, into stores its retail arm already serves, on the same logistical network that distributes its grocery, telecom and consumer-electronics brands.

The Varun Beverages signal

The clearest proof that this is now treated as a structural arms race rather than a marketing programme came inside Varun Beverages' Q1 CY2026 results. Consolidated revenue reached ₹6,721 crore (+18.3% year-on-year), profit after tax rose 20.1%, sales volumes hit 363.4 million cases (+16.3%), India volume grew 14.4% and international volume grew 21.4%. Inside the release was a strategic move that received less attention: Varun has entered a joint venture with Everest International Holdings to manufacture visi-coolers in-house, rather than continuing to source them from third-party appliance OEMs.

PepsiCo's largest emerging-market bottler is buying its way upstream into the chiller supply chain. That decision only makes sense if the visi-cooler is treated as a cost-of-distribution input on the manufacturing income statement, not a discretionary marketing expense. It is the strongest tell to date that the incumbents now believe the contest will run for a decade.

What the refrigerator boom is really telling the rest of the industry

The implications travel well beyond Coca-Cola, PepsiCo and Reliance. First, the cost of holding share in fast-growing emerging beverage markets has structurally re-rated upwards. Incumbents that once spent on advertising will now spend on refrigeration capex, and the marketing-versus-capex line will quietly migrate on income statements. Second, the model is replicable in any beverage-led emerging market where neighbourhood retail dominates — Indonesia, Nigeria, Vietnam, parts of Mexico — and Reliance has effectively published the playbook.

Third, Indian appliance OEMs are now leveraged proxies on Indian carbonated soft drinks competition in a way no analyst model captures cleanly. Fourth, the next leg of competition will be data. Every visi-cooler installed in 2026 is, in principle, a connected asset that can be metered, geo-tagged and used to enforce SKU exclusivity in real time. The brand that controls the chiller will increasingly control the shelf data — and through that, the merchandising contract.

India's carbonated soft drinks market is forecast to grow from $11.7 billion in 2025 to $17.6 billion by 2034, per IMARC Group. The terminal share map will depend less on whether consumers prefer Campa, Pepsi or Coke than on whose chiller sits in the corner store. For the first time in three decades, the answer is not obvious. For Coca-Cola and PepsiCo, defending India will require capital allocation discipline they have not had to demonstrate domestically in a generation. For Reliance, the question is whether the visi-coolers were the cheapest part of the campaign, or the most expensive.
