Billionbrains Garage Ventures Q4 FY26 FY26: ₹2,083 Cr Profit, 87.9% Quarterly Revenue Growth, But Is Groww Becoming Too Expensive?

1. At a Glance

Groww has gone from being the app your cousin used to buy his first mutual fund to becoming one of the most powerful retail-finance platforms in India. In Q4 FY26, Billionbrains Garage Ventures reported quarterly revenue of ₹1,505 crore, up 87.9% YoY, while PAT jumped 122% YoY to ₹686 crore. Full-year FY26 revenue stood at ₹4,645 crore and PAT reached ₹2,083 crore.

That is not startup behaviour anymore. That is a full-blown profit machine.

But the stock market is not stupid. At a market cap of ₹1,23,056 crore and a P/E of 59, investors are already paying tomorrow’s price for today’s earnings.

And that is where the real drama begins.

Groww is still overwhelmingly dependent on broking activity. Around 55% of Q4 FY26 revenue came from equity derivatives alone, while another 16% came from stocks. So nearly three-fourths of revenue still depends on people trading, punting, hedging, panicking, or simply trying to become the next options millionaire from their bedroom.

When markets are volatile, Groww wins. When markets are euphoric, Groww wins harder. But when markets go silent and retail traders vanish like New Year gym members in February, Groww’s earnings can cool quickly.

Management knows this risk. That is why it is aggressively expanding into lending, MTF, wealth management, AMC, insurance, and credit products. The company is basically trying to become a financial supermarket before the broking party slows down.

The challenge is that most of these new businesses are still in “burn cash now, maybe profit later” mode.

Fisdom lost ₹102 million in Q4 FY26. Groww AMC lost ₹214 million in the quarter. The company says both businesses are strategic, but for now, they are more like expensive toddlers who eat a lot and do not contribute much to the household income.

So the big question is simple.

Is Groww becoming India’s next great financial-services platform?

Or is the market already pricing in perfection?

That is what makes this story interesting.

2. Introduction

Groww was born in 2017 with a simple idea: make investing easy enough that even people who hate finance can buy a mutual fund without calling their CA uncle.

That simplicity turned into scale.

By June 2025, Groww had 18.07 million total transacting users, 14.38 million active users, and 26.27% market share among NSE active clients. In fact, Groww is now India’s largest broker by active NSE clients.

What is more impressive is where those users come from.

About 81% of users are outside the top six cities, and the platform covers over 98% of India’s pin codes. That means the company is not just riding the Mumbai-Delhi-Bengaluru investor wave. It is getting growth from Tier 2, Tier 3, and rural India.

That is probably the biggest reason investors are willing to pay such a premium valuation.

Groww is not just a broker anymore. It is becoming the default finance app for young India.

Its median user age is only 31. That means many users are just entering their prime earning years. If Groww can keep them inside its ecosystem for the next 10-20 years, it can cross-sell mutual funds, loans, insurance, PMS products, wealth management, MTF, and maybe even tax filing.

That is the dream.

And management is already building toward it.

The company acquired Indiabulls AMC in 2023, bought Finwizard Technology to expand into wealth management, and signed a deal with State Street to invest ₹580 crore into Groww AMC for up to 23% dilution.

The State Street deal is important because it gives Groww more credibility in asset management. Management openly said the AMC business is a multi-decade opportunity and that State Street brings global capability, credibility, and operational expertise.

But here is the catch.

Every shiny new business needs capital.

That is why the company raised ₹6,632 crore through its IPO and continues to deploy money aggressively into lending, MTF, technology, brand building, and acquisitions.

So while Groww looks extremely profitable today, it is also spending like a company that still believes it is in startup mode.

That mix of profits plus aggression is exciting.

It is also dangerous.

3. Business Model – WTF Do They Even Do?

Groww’s core business is broking.

When people buy or sell stocks, futures, options, commodities, or use margin funding, Groww earns brokerage income.

This broking segment contributed roughly 83% of Q1 FY26 revenue.

Within this, equity derivatives are the biggest cash cow.

In Q4 FY26, 55% of revenue came from equity derivatives, 16% from stocks, 8% from commodities, 5% from MTF, 7% from treasury income, and the rest from LAS, personal loans, and other income.

In simple language, Groww makes money when people trade.

But Groww also wants to make money when people do not trade.

That is why it is expanding into:

• Mutual funds
• Asset management
• Wealth management
• Insurance distribution
• Personal loans
• Loans against securities
• Margin trading facilities
• PMS and AIF products

The logic is simple.

If you already have millions of users trusting your app, why stop at brokerage?

Sell them more things.

That is exactly what management said during the concall. They want to use affluent customers already on Groww and push them toward wealth products like PMS, AIFs, private market products, and insurance.

The company also highlighted that customer acquisition cost becomes “almost zero” when it cross-sells wealth products to existing users.

That is powerful.

But there is a risk here too.

When companies try to do too many things at once, execution becomes harder.

Groww is now simultaneously running broking, lending, wealth, AMC, insurance, commodities, MTF, and credit.

At some point, investors have to ask:

Is Groww building India’s next financial giant?

Or is it slowly turning into a fintech buffet where management keeps adding dishes before checking if customers even want dessert?

4. Financials Overview

Since the latest official heading is Quarterly Results, this is treated as quarterly reporting. Q4 FY26 EPS annualisation is not required because March quarter gives full-year EPS.

Metric	Latest Quarter Q4 FY26	Same Quarter Last Year Q4 FY25	Previous Quarter Q3 FY26
Revenue	₹1,505 Cr	₹801 Cr	₹1,216 Cr
EBITDA	₹938 Cr	₹388 Cr	₹720 Cr
PAT	₹686 Cr	₹309 Cr	₹547 Cr
EPS	₹1.09	₹1.69	₹0.89

Q4 was one of those quarters where almost every line item looked beautiful.

Revenue jumped, margins improved, PAT exploded, and operating leverage kicked in hard.
