The company confirmed the 100% acquisition of Fisdom was consummated on October 3, 2025, and operations were consolidated in the Q3 FY26 results. (2 met across 2 tracked commitments)
“Furthermore, Fisdom, which we recently acquired, at its existing run-rate would add 3 - 4% to Revenue from Operations.”
Management confirmed that consolidation of the wealth acquisition (Fisdom) began in October, reflecting in the Q3 FY26 results. (3 met across 3 tracked commitments)
“We think it is better to look at Adjusted EBITDA to determine the operating health of the company due to the one-off adjustments which will be normalised Q4 FY26 onwards.”
Diversification is progressing with commodities now contributing 4% to the top line and MTF contributing 6% to total revenue, supporting the shift away from derivative concentration. (3 in progress across 3 tracked commitments)
“So I think it is beyond 50, definitely it can come below 50. But that is like output number in the way to look at where if everything else goes or grows faster, this definitely can come off.”
The wealth business (Fisdom) is currently being integrated. Management reported Q3 revenue for this piece at INR 29 crores and expects growth to continue quarter-on-quarter as they scale offerings to affluent Groww customers. (1 in progress across 1 tracked commitment)
“And roughly 3% revenue is coming from that business. And obviously that business is growing well and over a period of time, the contribution will keep on increasing.”
The reported revenue for the wealth piece (Fisdom) was INR 29 crores for the quarter, which analysts noted is a decline from the previous run rate of approximately INR 40 crores per quarter. (1 missed, 1 met across 2 tracked commitments)
“For it to be profitable, we need to grow our AUM 5 - 6x and this is expected to be achieved over the next few years.”

How durable is the business?
The segment is undergoing a structural shift where the total number of active F&O users has decreased (from ~2 million to 1.47 million), but the revenue per user is rising because remaining traders are executing larger ticket sizes due to new regulations and increased lot sizes. (1 shifted)
“Because some of the -- we already had like more than almost 2 million customers who were active on F&O side. Today we have 1.47. Large part of that is actually existing customers.”
The company is shifting its focus toward 'Affluent Users' who require specialized wealth products, indicating an evolution from a pure discount broker to a wealth management platform. (1 shifted)
“emergence of Affluent Users... now constituting 34% of Total Customer Assets, compared to 31% in Q2 of the previous year. They need specialised wealth products such as AIF, PMS, and Advisory.”
The revenue share from derivatives is contracting as the company sees a structural shift toward cash and other products, partly due to regulatory churn and diversification efforts. (3 contracting, 1 expanding across 1 engine)
“Total Income mix, by Products (% Share) ... Equity Derivatives 55%”
While total transacting users grew, the active client base on the NSE has seen a contraction over the last year, reflecting broader industry trends, though market share improved. (1 contracting)
“Total Transacting Users 21.6 Mn +25% YoY”
The company earns 'Float' income, which is interest generated from customer cash balances held on the platform. — Float (8.6% revenue share)
“Total Income mix, by Products (% Share) ... Float 8%”

Where does growth come from?
User acquisition remains steady with a 25% year-on-year increase, though the quarterly growth rate of 6% suggests a stable rather than accelerating pace of expansion. (1 steady across 1 signal)
“While the Indian capital markets have expanded meaningfully over the past decade, penetration is still in the single digits. This has the potential to grow 3 - 4x over the next decade or so.”
User acquisition remains robust with a high organic component (80%), though management notes a shift toward higher quality, more active users rather than just headline demat counts. (1 steady, 2 accelerating across 3 signals)
“EBITDA... ₹9,704 Mn | 66.1%... ₹4,045 Mn | 50.6% [Q4 FY25]”
EBITDA margins are expanding as revenue growth significantly outpaces fixed costs, which are only expected to grow at 10-20% annually. (1 accelerating across 1 signal)
“sustained periods of market underperformance driven by continued selling by FIIs typically impacts investor sentiment. This, in turn, leads to moderation in new user acquisition”
A new growth trend has emerged with the launch of Commodity Derivatives. In its first full quarter, it already accounts for 3.5% of total income and has attracted 255k active users. (1 new trend across 1 signal)
“We introduced Commodity Derivatives in a phased manner in Q2 FY26 and saw a sharp adoption in Q3... In revenue terms, it was 3.5% of Total Income in Q3, whereas for Q2, it was less than 0.5%.”
Management maintains a long-term bullish outlook on market penetration, noting that only 5% of the adult population currently invests. They highlight a massive 'awareness-to-participation' gap as the primary growth engine. (1 steady, 1 accelerating across 2 signals)
“In India, presently there are 45 Mn investors (5% of the adult population)... the runway for growth remains significant.”

What could break the thesis?
The risk is easing. While NSE active clients fell YoY (11.9 Mn vs 12.3 Mn), market share actually increased to 26.3% from 25.6%, suggesting Groww is outperforming the industry decline. (1 easing)
“NSE Active Clients: 12.3 Mn (25.6%) in Q2 FY25 to 11.9 Mn (26.3%) in Q2 FY26.”
EASING. Management reported a reduction in headcount (down 100 employees QoQ) and noted that fixed costs are expected to grow only 10-20% while revenue is growing faster, leading to EBITDA margin expansion. (1 easing)
“Previous quarter, we had 1,450 approximate employees. This quarter, we had 1,350. So we've reduced it by 100... our variable cost is roughly like - 10%... Rest all is more on the fixed nature.”
CAC is intensifying significantly. The cost to acquire a customer in H1 FY26 was ₹1,374, compared to ₹796 in H1 FY25, driven by high-profile branding spends (Asia Cup, KBC). (1 intensifying)
“The CAC for H1 FY26 was ₹1,374 and is higher than the historical averages. If we look at the same period last year (H1 FY25)... it was ₹796.”
The risk is easing as the revenue mix from derivatives has dropped from previous levels and is expected to fall below 50% as the company diversifies into cash, commodities, and wealth management. (3 easing)
“So derivatives already has come off from earlier numbers, I think it will probably come off further as well... I think it is beyond 50, definitely it can come below 50.”
The risk is stable; while competitors offer aggressive rates (7.99%), Groww maintains a 14.95% yield and focuses on user experience rather than price wars. (2 stable, 2 intensifying)
“We have players offering it at 7.99 very aggressively... Our pricing is simple. It is 14.95%... pricing is least of the concern when looking at the selection of the platform.”
