Zerodha, the Bengaluru-based discount brokerage founded by brothers Nithin and Nikhil Kamath, has solidified its position as India’s most profitable startup, crossing a revenue of $1.1 billion (₹9,372 crore) in FY24 with a staggering profit of ₹5,496 crore. This milestone, driven by a 37% revenue surge and an 89% profit jump from FY23, underscores Zerodha’s dominance in India’s financial services landscape. However, co-founder Nithin Kamath warns of looming regulatory challenges that could dent revenues by 30–50%. This article explores Zerodha’s financial triumph, the threats it faces, and the Kamath brothers’ strategic plans to navigate the future. Why does this matter? Zerodha’s success and proactive diversification offer a blueprint for startups aiming to balance profitability with resilience in a volatile market.
A Financial Powerhouse in FY24
In FY24, Zerodha reported a revenue of ₹9,372 crore, up 37% from ₹6,832 crore in FY23, and a net profit of ₹5,496 crore, a remarkable 89% increase from ₹2,908 crore, according to data from Tofler. With an operating margin of 57%, Zerodha outshines competitors like Groww, which reported a net loss of ₹805 crore in FY24 due to a one-time tax expense. The company’s lean operations, with just 1,200 employees (including a 35-member tech team), and a 24% reduction in employee costs to ₹474 crore, have driven its industry-leading profitability. “Our net worth is nearly 40% of the ₹5.66 lakh crore in customer funds we manage, making us one of the safest brokers,” Nithin Kamath noted in a September 2024 blog post.
Zerodha’s client base, with 7.5 million active users as of May 2024, accounts for 16% of BSE’s active clients. The platform’s flat-fee model—zero brokerage for equity investments and ₹20 per trade for options—has democratized investing, contributing to over ₹1 lakh crore in unrealized client profits in FY24. Despite this, Kamath cautions that a “perfect storm” of regulatory changes could disrupt this growth trajectory.
Regulatory Threats on the Horizon
The Securities and Exchange Board of India (SEBI) has introduced measures to enhance transparency and protect retail investors, particularly in the futures and options (F&O) segment, which drives a significant portion of Zerodha’s revenue. Key changes include a “true-to-label” circular effective October 1, 2024, requiring uniform exchange fees, which Kamath estimates will cause a 10% revenue dip. New F&O regulations, such as limiting exchanges to one weekly index expiry and increasing contract sizes, could lead to a 30–50% revenue drop. Additionally, a hike in Securities Transaction Tax (STT) from October 2024 is expected to impact futures trading significantly.
Other challenges include SEBI’s revised Basic Services Demat Account (BSDA) thresholds, allowing full annual maintenance charges only for holdings above ₹10 lakh, and the removal of account opening fees in response to competition from platforms like Groww and Angel One. Kamath also highlighted the end of Zerodha’s referral program, which previously drove 10% of new business, as a growth constraint. “The best days for the broking industry may be behind us,” Kamath warned, citing increased competition and market volatility risks.
Kamath Brothers’ Strategic Pivot
To counter these threats, the Kamath brothers are diversifying Zerodha’s revenue streams beyond F&O trading. Through their venture arm, Rainmatter, Zerodha has invested ₹680 crore in over 120 startups across fintech, climate, health, and sports, including a ₹250 crore stake in IPO-bound InCred in June 2025. The company is also launching Margin Trade Funding (MTF), Loan-Against-Securities via Zerodha Capital, and expanding its asset management company, Zerodha Fund House, which manages ₹3,000 crore in AUM with smallcase. A joint venture with Finshots, Ditto Insurance, further broadens its portfolio.
Zerodha’s Rainmatter Foundation, with a ₹1,000 crore commitment to climate and environmental causes, reflects the brothers’ focus on social impact. Nikhil Kamath’s WTF Fund, launched in 2023, supports young entrepreneurs under 22 in sectors like fashion and beauty, with non-dilutive grants of ₹20 lakh each. “We’re pivoting to reduce reliance on derivatives,” Nithin Kamath stated on X, emphasizing new products and investments to sustain growth. The brothers’ bootstrapped approach, owning nearly all of Zerodha’s shares, allows flexibility without external investor pressure, maintaining a valuation of $7.7 billion as per a December 2024 Hurun report.
Why Zerodha’s Success Matters
Zerodha’s FY24 performance cements its status as a trailblazer in India’s startup ecosystem, with a profit margin that dwarfs venture-backed competitors like Groww and Upstox, valued at $3 billion and $3.4 billion, respectively. Its lean team and frugal operations—highlighted by hiring only five tech employees in four years—offer a masterclass in efficiency. The company’s 16% BSE market share and ₹5.66 lakh crore in assets under custody underscore its scale, yet its decision to remain private reflects a commitment to customer-centric growth over market hype.
The Kamath brothers’ journey from college dropouts to billionaires, ranked eighth among India’s self-made entrepreneurs by Hurun, inspires aspiring founders. Their investments in startups like Nazara Technologies (₹100 crore in 2023) and Biopeak ($3.5 million in 2025) show a knack for spotting high-potential ventures. As India’s startup ecosystem grows, with 112 unicorns valued at $350 billion, Zerodha’s ability to navigate regulatory headwinds while diversifying could set a benchmark for sustainable scaling.
A Case Study in Resilience
Zerodha’s rise mirrors other bootstrapped successes like Zoho, which reported ₹2,836 crore in FY23 profits. Unlike VC-funded rivals facing valuation pressures, Zerodha’s independence allows it to prioritize long-term stability. The Kamath brothers’ diversification into fintech, real estate (via Nikhil’s Gruhas), and social impact ventures like Rainmatter Foundation positions them as visionary leaders. Nithin’s recovery from a January 2024 stroke, shared candidly on X, underscores their personal resilience, with lessons on balancing health and ambition resonating with entrepreneurs.
The regulatory challenges ahead test Zerodha’s agility, but its strong net worth and diversified portfolio provide a buffer. As Nithin noted, “You can’t control outcomes, only inputs,” a philosophy driving their pivot toward non-derivative revenue streams. For India’s startup ecosystem, Zerodha’s story is a testament to building a profitable, customer-first business in a competitive, regulated market.
