In 2017, media reports had surfaced that the two players were in merger talks.
The Zomato spokesperson further said that the latest "speculation is absolutely untrue". Swiggy, however, refused to comment on the report.
Amazon is gearing up to launch its own online food delivery division to compete with food delivery apps in the Indian market.
The retail behemoth already has a robust existing workforce in the country that can be utilized along with hiring more delivery partners to beat the competition.
According to Prabhu Ram, Head-Industry Intelligence Group (IIG), CMR, the food delivery business is no longer a two-horse race and is increasingly witnessing cut-throat competition.
"With the entry of new players, including the likes of Amazon and Uber Eats, a potential merger of Zomato and Swiggy would make sense," Ram told IANS.
Zomato is currently delivering 1.3 million orders a day from 150,000 restaurants across India at more than 10 orders per restaurant per day.
The company's revenue for the first half of the financial year 2019-20 saw a massive three-fold jump -- from $63 million in the same period in 2018-2019 to $205 million. Zomato is currently present in 556 cities.
Swiggy has expanded its services to 500 cities in India, matching rival Zomato's reach in the country. Swiggy, which has added 60,000 new restaurants in the past six months, said in October it would expand to 600 cities by December 2019.
Since April 2019, Swiggy has increased the number of restaurant partners by almost 1.8 times to 1.4 lakh restaurants currently. In tier-3 and tier-4 cities specifically, Swiggy has onboarded over 15,000 restaurants in the last six months.
The market is piping hot as according to a recent study by business consultancy firm Market Research Future, the online food ordering market in India is likely to grow at over 16 per cent annually to touch $17.02 billion by 2023.
Uber Eats last week told IANS that it is not only going to stay put in the growing food tech industry in India but is also building strong linkages with restaurant partners for a seamless delivery experience for its customers.
In the next three years, the food tech industry in India is going to grow from $4 billion to $15 billion.
"This industry is perfect for Uber Eats. Right now, we are more focused on delivery with the restaurant partners. We are learning in the India market and making our mark in that space before we can add anything more to it," Kotecha told IANS.
The Zomato-Swiggy merger, if happens, will immediately come under the scrutiny of the Competition Commission of India (CCI).
"Combining the market reach and strength of the two players would enable them to take on intensified competition better. That said, it remains to be seen if such a potential merger would come under the regulatory scanner," added Ram.
