Barely five years old, the sector has already seen explosive growth. Blinkit, snapped up by Eternal Ltd. (then known as Zomato) for about $570 million just three years ago, is now worth at least $15 billion, according to some analysts. Zepto, valued at $6 billion, is eyeing a public listing next year. Swiggy Ltd., whose Instamart is another industry heavyweight, is valued at $12 billion, with its quick-commerce arm estimated to account for roughly 40% of that.
