And sure enough, at present, Reliance Industries is working on oil, telecom, retail, and green energy as its business. Not just that though, Jio is the top telecom player and Reliance Retail is the largest retail company in India. For now, just know that Reliance is still the giant of India’s business world, it still ranks in the top 100 global firms.
2. Tata Group
Tata is one of the founding companies incorporated by India’s oldest business families, they have been trustworthy and reputed ever since. Like, sadly, Sir Ratan Tata has passed away, but even in 2025, this conglomerate is still very much in business.

No doubt that with all their strength and growing customer base, HDFC is one of the most important financial companies in India.
4. ICICI Group
And then, well, ICICI Group has a market value of ₹8.71 trillion Bank in India. How and why? Well, for now, just know that ICICI Bank their largest company is the 2nd-largest private bank in India.

5. Bharti Airtel (Bharti Enterprises)
You just can’t deny the fact that Airtel is still one of India’s biggest telecom companies in 2025 and that fact right there is not going to change anytime soon, especially not with a HUGE market value of ₹9.81 trillion. Right? Sure, they’re the ones to successfully introduce 5G in big cities of the country and trying to roll it out in other parts as well, on top of that, they’re onto this new AI scene, which is working out pretty well for them as well. That’s it? Oh, nah, you see, Airtel Payments Bank is also growing fast, especially in rural areas where people need banking services.
6. Infosys
If you just keep an eye on the business scene of India, there is no way you don’t know anything about Infosys or haven’t heard of this name yet, it is just not possible. Why? Simple actually, it sure is one of the biggest tech aka IT companies in the country. How big? Oh, with a market cap of about ₹7.52 trillion, THAT big! Get it?

Well, you know it, but not a lot of people right here in India have any idea of that. Since they have so many products and so many brands, thier huge market cap seems pretty much understandable.
9. ITC Limited
ITC had to be one of the most successful and well-known companies in the country, and that’s just the very reason right there why they have a huge market value of about 5 trillion rupees as of 2025.
