Nithin Kamath Net Worth

Nithin Kamath has an estimated net worth of $4.7 billion, according to Forbes Real-Time Billionaires, Nithin Kamath profile (figures as of October 20, 2026). That is up from $2.7 billion in 2023.

Nithin Kamath is an Indian entrepreneur best known as the founder and CEO of Zerodha. He started in the stock market at 17, first handling his father's trading account. From 1997 to 2004, he worked as a self-employed proprietary trader. During part of that stretch, from 2001 to 2004, he also worked nights at a call centre while trading during the day.

His biggest career move came in 2010, when he cofounded Zerodha with his brother Nikhil Kamath. The Bangalore-based firm introduced a discount broking model with a flat fee of ₹20 per trade instead of percentage-based charges. Zerodha grew into one of the largest brokerage firms in India, with more than seven million clients. Kamath also founded Rainmatter in 2015 and later co-founded True Beacon with Nikhil Kamath.

How Nithin Kamath makes money

Kamath's wealth is tied to financial services, mainly through Zerodha. Before launching the company, he spent years as a trader and later worked from 2004 to 2010 as a sub-broker for Kamath Associates, a franchise of Reliance Money. In 2010, he and Nikhil Kamath started Zerodha. Its discount broking model helped it stand out in India by charging a flat ₹20 per trade regardless of order size.

Zerodha became the main engine of his fortune as it expanded to more than seven million clients. Kamath also built other businesses around investing. In 2015, he started Rainmatter, a fund and incubator that backs fintech companies and ventures focused on financial inclusion. He also co-founded True Beacon, an investment management firm for ultra-high net worth investors that runs on a zero-fee model.

Forbes net worth timeline

Forbes estimated Kamath's net worth at $2.7 billion in 2023, then $4.8 billion in 2024. In 2025, Forbes put it at $3.9 billion, and in 2026 at $5 billion on the World's Billionaires List. Forbes' real-time billionaires tracker placed him at $4.7 billion as of October 20, 2026. Those swings line up with how closely his wealth is tied to Zerodha and the brokerage business.

One key business factor came in November 2024, when the stock exchange's regulator tightened rules for futures and options traders, who are Zerodha's main customers. Forbes notes that Zerodha's business took a hit after that change. Kamath's broader money story also includes newer ventures beyond broking, including Rainmatter and True Beacon, but Zerodha remains the central source behind the Forbes estimate.
